All Departments in the electrified area which require traffic blocks, power blocks or ‘permit-to-work’ in the danger zone of traction equipment or who require overhead line staff and/or bonding staff to be present at site for scheduled maintenance works, shall give notice sufficiently in advance to the DEE/Tr.D which in any case shall not be later than 10 hours every Monday morning, in the prescribed form showing: 3.1.1 the nature of the work and the date and time on which it is to be performed. 3.1.2 by whom the work is to be carried out. 3.1.3 location of the work and the section of the lines to be blocked. 3.1.4 the trains between which the block is required and 3.1.5 whether the track will be available for diesel traffic. 3.2 The requirements of all departments for traffic block/power blocks and ‘permit-to-work’ shall be coordinated by the office of the DEE/Tr.D in consultation with the DOM and a consolidated statement forwarded to the DOM concerned, by 12 hours on every Wednesday for inclusion in the weekly programme of traffic and power blocks. 3.3. Works of an urgent nature shall be attended to by obtaining emergency blocks and ‘permit-to-work’ from the TPC. 3.4.A weekly programme of work involving traffic blocks, power blocks and ‘permit-to-work’ shall be prepared in the office of DOM and despatched to all concerned by Friday evening, for the week commencing on the following Monday. Note:- The procedure detailed in paras 4, 5 and 6 shall be followed for obtaining the power block and ‘permit-to-work’ in each case as prescribed, even though the work is included in the weekly programme. 4.1. When a power block has been sanctioned, the TPC shall issue to the SCOR a power block message (in the prescribed from) in duplicate either through a messenger or by telephone with exchange of PNs. The SCOR shall obtain confirmation from the Station Master that the section will be blocked for electric traffic. He shall then, either return one copy of the written message duly acknowledged indicating thereon the time from which the block will be given or send a phone message to the TPC giving the same information supported by a PN. The TPC shall thereafter arrange to isolate and make dead the portions of electrical equipment concerned at the time indicated by the SCOR and issue a ‘Permit-to- work’ thereon, as detailed in paras 5 and 6 below. 4.2. However, in case of an emergency, the TPC shall switch off the power first and then, advise the SCOR of the power block imposed and reasons for doing so. 4.3. When ‘Permit-to-work’ on the electrical equipment has been cancelled and the TPC has restored normal conditions, he shall cancel the power block message issued to the SCOR, either by giving a cancellation message in duplicate or by telephone with exchange of PNs. 5. Method of obtaining ‘permit-to-work’ in the danger zone of overhead equipment for work by authorised persons. 5.1. Except as detailed in SR.17.04.10, permit-to-work shall be obtained by authorised persons from the TPC, who shall carry out (through remote control) or order the switching operations necessary to isolate the portion of the equipment concerned. When the TPC receives confirmation that switching operations have been correctly carried out, he shall inform by telephone message with exchange of PNs, the authorised person stating clearly that the electrical equipment has been made dead. The information shall constitute a ‘permit- 307 to-work’. ‘Permit-to-work’ shall be issued in this manner only to authorised persons not lower in grade than a Linesman. 5.2. On receipt of ‘permit-to-work’ and before work is commenced; the electrical equipment specified shall be earthed as per rules in force. Each working party shall be protected by independent earths. 5.3. On completion of the work, the person who received the ‘permit-to-work’ shall ensure that all men and materials have been withdrawn from the electrical equipment and its vicinity. He shall then remove the earths and inform the TPC either by written memo or by a phone message supported by a PN that the work for which the permit-to-work was issued has been completed, men and materials have been withdrawn from the specified electrical equipment and the same maybe made live. Such procedure shall constitute cancellation of the ‘permit-to-work’. 6. For work by other than authorised persons- 6.1. If work is to be carried out on or adjacent to any part of the electrical equipment by other than authorised persons, such work shall not commence until the ‘person-in-work’ card issued to him by an authorised person. 6.2. The ‘Permit-to-work’ shall be obtained from the TPC by an authorised person who shall earth the electrical equipment specified in charge of the work holding an acknowledgement on the other copy. A duplicate of every ‘permit-to-work’ card shall be retained in the personal possession of the authorised person who issued it. 6.3. On completion of the work and when all men and materials have been withdrawn from the electrical equipment and its vicinity, the person-in-charge of the working shall cancel his ‘permit-to-work’ card and return it to the authorised person who issued it. The authorised person shall in turn cancel the ‘permit-to-work’ as detailed in S.R.17.04.5.3. above. 7. If telephone communication with the TPC is interrupted, when a ‘permit-to-work’ is to be cancelled, the authorised person to whom the ‘permit-to-work’ was issued shall arrange locally to restore normal (live) conditions, the positions of electrical traction or overhead equipment specified in the ‘permit-to-work’ and to cancel the ‘power block’ if possible. 8. Whenever work has to be carried out by more than one working party, the ‘permit-to- work’ shall be issued by the TPC only to one authorised person who alone shall be responsible under this rule, for all work on the portion of electrical equipment, specified in the ‘permit-to-work’. Any additional party or parties may work on the same portion of electrical equipment only with the permission of this authorised person who shall inform all parties of the total number of parties working on the same portion of electrical equipment. The authorised person shall cancel the ‘permit-to-work’ only when he is satisfied that all working parties have withdrawn all men and materials and removed the earths from the electrical equipment. In the event of telephone communication being interrupted, the responsible person shall proceed as provided for in para 7 above. 9. The number of each ‘permit-to-work’ issued, shall be entered in the log book of TPC, together with the particulars and time when the equipment is made dead for the work and re- energise after completion of the work, as per information received from the authorised person concerned 10. In case of work to be done inside the electric Loco sheds, the application for ‘permit-to- work’ shall be made to the TFO/ATFO/Chargeman (RS) who shall arrange for the issue of the ‘permit-to-work after getting the switch of the inspection bay or the feeders opened. No intimation to the TPC is necessary and the ‘permit-to-work’ shall be returned for cancellation by the person-in-charge of the work to the TFO/ATFO/Chargeman (RS) before the switches are closed. 11.1. Local arrangements may be made with the Station Master, Cabin Assistant Station Master, Yard Master and others responsible for the movement of traffic, for power blocks in such sidings which do not affect the movement of trains on main running lines, loop lines, and reception and departure lines in yards. The TPC shall, however, be kept informed as to 308 when the power block is taken and cancelled. The Station Master, Cabin Assistant Station Master, Yard Master and other persons shall also advise the SCOR of such blocks. 11.2. Local blocks shall be arranged on the forms prescribed for the purpose. 12.1. In order to prevent electric rolling stock from being admitted into a track or cross over of which the overhead equipment is made dead, or for which a ‘permit-to-work’ has been issued, the levers of signals and points in the signal cabins governing such movement of electric rolling stock shall be protected by means of ’power block collars’. If the points and signals are locally operated, the same should be locked and the keys be kept with the Station Master. 12.2. The SCOR on receipt of a power block message from the TPC shall repeat to all Station Masters concerned the said message indicating the time from which the block is to commence. Each Station Master shall record and acknowledge the message with a PN and the time of receipt and then block the electric traffic on the line or lines described from the time indicated and place ‘Power block collars’ on the appropriate levers. When lever frames or other equipment in signal cabin are controlled electrically from Station Master’s office, the Station Master shall place the ‘Power block collars/pins’ on the slides of electric slide instruments or on the keys of electric transmitters or interlocked key boxes. The Station Master shall also ensure that ‘power block collars’ are placed by Cabinmen/Levermen concerned on the relevant levers. 12.3. The ‘Power block collars’ shall not be removed until the Station Master receives message from the SCOR and acknowledges the message supported by a PN cancelling the power block. The SCOR shall not issue such a message unless he has received a written message or phone message supported by a PN from the TPC cancelling the power block. NOTE: In all cases mentioned under paras 3, 4, 11 and 12 the Station Master must record the information in the Station Master’s diary. 13. When electric locos are placed in sidings for washing, cleaning etc., the section switch for that particular siding shall be opened by the person-in-charge of washing and the keys retained by him. 14. In the event of any accidents occurring in which electric rolling stock is involved or where damage to overhead structures or equipment takes place, the railway servant who notices it shall take necessary precautions against danger of electric shock and shall inform the nearest Station Master, SCOR and TPC to take immediate action to cut off power supply, if necessary and restore the equipment as early as possible. The line shall not be re-opened for traffic until a responsible Official of electrical department inspects the site and certifies that the line is safe for the passage of trains. 15. The only authorised person to issue ‘permit-to-work’ is the TPC who will sign the prescribed form for DEE/Tr.D. The ‘authorised person’ may issue the certificate that the line is safe for passage of trains as required in para 7. 16. Responsibility for staff and equipment when at work shall always be under the charge of the senior member who shall be responsible for all work being carried out correctly in accordance with the rules prescribed and such other instructions as are specifically issued by the Railway Administration. In the case of illiterate staff working on or near electrical equipment, the circumstances of the work as affecting their safety and the safety of the electrical equipment shall be explained to them by the senior members. 16.1. When repair or adjustment to overhead equipment makes it necessary for a train to proceed cautiously, an authorised person shall be present at the site of work and shall be responsible for showing the signals prescribed in Rule 15.09 and subsidiary rules thereunder. 16.2. Before commencing work on overhead equipment or in cases of breakdown of overhead equipment, when it is necessary for a train to proceed cautiously, the TFO/OHE, responsible for such notification shall arrange for issue of Caution Orders (See S.R. 17.03.2.3). 309 16.3. No alteration or addition shall be made to any equipment which may infringe the standard dimensions, whether permanently or temporarily. If an infringement is unavoidable, sanction shall first be obtained from the DEE/Tr.D. 16.4. Care shall be taken to ensure that covers of tank wagons, funnel of steam cranes or such other items are not left in such a position as to foul the traction overhead equipment. 16.5.1. No steam or hand-crane shall be worked adjacent to such traction overhead equipment which is not dead and earthed. All movements of the crane jib shall be carefully controlled to avoid fouling the traction equipment. Wherever possible, the direct blast form the crane funnel to the overhead equipment and particularly to section insulators shall be avoided. 16.5.2. Except in an emergency, to work a crane adjacent to overhead equipment, 24 hours notice shall be given to the DEE/Tr.D in order to make arrangement for overhead equipment staff to standby. When possible the working of cranes shall be included in the weekly programme detailed in SR. In an emergency, the TPC shall be advised and he shall make arrangements for overhead equipment staff to standby. 16.5.3. Cranes shall not be worked adjacent to traction overhead equipment unless the overhead equipment staff is present. 16.6. Before any work is commenced on electric locomotives standing in the loco shed, stabling depots or on a station platform line, the staff shall take all precautionary measures to ensure safety. Delay or inconvenience to traffic should not interfere with the man taking reasonable precautions to protect himself. 16.7. Each man should provide for his own protection independent of every other man, except where one man is assisting another, in which case, the person in charge of the work is responsible for the proper protection of himself and his assistants. 16.8. For the protection of staff employed upon electric locos at loco sheds/stabling depots or on platform, warning boards shall be placed in a conspicuous position at the ends of the electric locos by the staff concerned before proceeding to carry out any work in or under the electric locos. These boards, painted with the legend ‘not to be moved’ in white on a red background, should on no account be removed, except by the staff, who placed them in position. 16.9. Every possible precaution shall be taken to protect the staff while at work, and as an extra precaution Loco Pilots are prohibited from entering any driving compartment while the ‘warning boards’ are in position. 16.10.Warning boards shall on no account be removed and power supplied until all precautions have been taken to ensure that all men are clear of danger. 16.11. The whole of the overhead contact system comprising of contact wire, catenary, droppers, register arms and pull-off wires shall always be considered live and men working over the electrified area shall take care to see that nothing comes in contact since danger of death results from coming in contact, directly or indirectly, with the overhead equipment. 17. Work on Electrical equipment: 17.1. Before commencing and for the whole time work is being performed on any part of the electrical equipment or adjacent thereto, that part of the electrical equipment shall be made dead and earthed save and except as in clauses 17.2 and 17.3 hereunder. Every working party shall be protected by independent earths. When it is necessary, minimum of two earths shall be employed, to the overhead equipment or transmission lines one on each side of the working party. 17.2. Except in the case of indoor high voltage electrical equipment, authorised staff may work on electrical equipment which is live or dead and not earthed subject to adequate precautions taken for the safety of such staff, the authorisation and precautions shall be prescribed by the Railway Administration. 17.3. Work may be performed by authorised staff on indoor high voltage electric equipment which is not earthed but which is isolated from the main supply of electrical energy in such a manner that it is safe to work on. The Railway Administration shall prescribe adequate precautions to cover these conditions. 310 17.3.1. No work on live or any unearthed indoor or outdoor equipment above 400 volts is permitted. The only occasion when maintenance staff may work on unearthed equipment, after it has been isolated, is for the purpose of taking insulation tests. On completion of tests the equipment shall be earthed, before any work is started. 17.3.2. After the feeder is made dead, it shall first be discharged by throwing an earthed chain over the conductors. The feeder line is then connected to earth by means of stranded copper cable of adequate size securely connected to earth and the conductor. 17.3.3. Interruptors or isolator switches which have been opened for the purpose of isolating electrical equipment for maintenance shall have a danger notice displayed in a prominent position on the interruptor or operating handle of the switch or on the enclosure containing isolator switch and control apparatus as well as on the corresponding switches in remote control centre. 17.3.4. Before any work is undertaken on a section of overhead equipment which is normally live or any part of the structure adjacent thereto or supporting such equipment situated at a distance of less than 2 metres from the live parts, the overhead equipment shall be made dead and earthed. A minimum of two earths shall be provided one on either side of the working party. In case, the work is spread over several sub-sectors, additional earth shall be provided close to the feeding points of supply control posts involved. 17.3.5. No work shall be attempted on insulted overlap spans, or on section insulators unless the adjoining sections of overhead equipment on either side are made dead and earthed. In the case of a sectioning post, the isolator switch, the bridging or section interruptor, bridging overlap span shall be closed. 18. Works on roofs of rolling stock— No person shall climb on to the top of engines or on to the roof of carriages or wagons when those vehicles are located beneath the overhead equipment except when the overhead equipment is dead and earthed. 18.1. Work on pantographs and roof of rolling stock shall normally be carried out on special sidings where switches are provided for making such sidings dead and earthed. 18.2. Traction Engine Examiner or other authorised person in-charge shall be responsible for making dead the overhead equipment over the track of inspection lines in loco sheds and stabling sidings before permitting the work to be done on the roof of electric rolling stock. The overhead equipment over these tracks shall not be energised except by the authorised person in-charge, who shall be responsible for every precaution being taken to ensure that every thing is in order and all staff are cleared off the roofs and live parts, before energizing the equipment. 18.3..1. At stations and yards, an authorised person shall arrange to make dead and earth the overhead equipment and a ‘permit-to-work’ card shall be obtained by the staff concerned before the work on the roofs of rolling stock or engines is commenced. On completion of work, the card shall be returned to the authorised person for cancellation. The authorised person shall then satisfy himself that everything is in order and that all staff are cleared off the roofs and live parts before energising the equipment. 18.3.2. Prescribed working rules for isolating and making dead the sections of overhead equipment for watering carriages, shall be followed at watering stations. 18.4. The SWR issued to each station, loco shed etc., shall specify the switches the operation of which will make a section dead or live. 19. Register of Message:- All messages relating to operation of switches, issue of ‘permit-to-work’ and other important communications shall be recorded in a register by both the sender and the receiver together with the time when sent and the time when received. 19.1 All messages relating to operation of switches and issue of ‘permit-to-work’ shall be confirmed by PNs. 19.2 All messages together with the PNs issued and received shall be recorded in the books specially maintained for the purpose. 311 20. Emergency telephone circuit. 20.1. Functions- This circuit is provided to facilitate the train crew/ traction maintenance gangs to get in touch with the TPC with the least possible delay, specially during emergencies/accidents since due to replacement of aerial lines by underground cables, it will no longer be possible to hook a portable telephone on to the control line. This circuit will be operated by the TPC and is located in the remote control office. 20.2. Location- Emergency socket boxes are provided along the track at an interval of 900 metres generally. Portable emergency telephones are given to maintenance gangs and train crew. These telephones can be plugged into the emergency socket boxes to enable the man on the spot to communicate with the TPC. Sockets for emergency telephones are also provided near the OHE isolating switches, sub-sectioning and sectioning posts, grid stations and feeding posts. 17.05. Warning to staff and public.–– (1) All electrical equipment shall be regarded as being live at all times and consequently dangerous to human life, save and except in cases, where the electrical equipment has been specially made dead in accordance with special instructions. Caution notices shall be prominently fixed near all vulnerable places to warn staff and public to exercise due caution. (2) No person shall climb on the top of engines or tenders or on the roofs of carriages or wagons when those vehicles are located beneath overhead equipment except when the overhead equipment is dead and earthed in accordance with special instructions. SR.17.05.1. All railway servants other than those deputed to work on or near electrical equipment shall keep away therefrom. 2. Electric shock. 2.1.

The instructions regarding the treatment of persons suffering from electric shock shall be exhibited at all supply control posts, overhead equipment maintenance depots, tower wagon sheds, loco sheds and signalling cabins. 2.3. In the event of electric shocks, the treatment laid down for respiration shall be carried out immediately. 2.4. The names and telephone numbers of the nearest railway and civil doctors and hospitals shall also be exhibited at all the places stated in para 2.1. 3. Fire – 3.1. In the event of fire on or adjacent to any electrical equipment, the affected part shall immediately be completely isolated from its source of supply of electrical energy. To extinguish the fire, the extinguishing arrangements made by the Railway Administration for this purpose shall be used. Adequate extinguishing arrangements shall be made by the Railway Administration. In the event of fire on or adjacent to electrical equipment being noticed by a railway servant who is not an authorized person, he shall take action in accordance with Rule 6.10. 3.2.1. In the event of a fire of any part of any traction electrical equipment, the affected part at first be completely isolated from distribution system, if this has not been done automatically. If arching continues due to feed from adjacent supply control posts, it shall be got interrupted either by remote or local operation of switches. The fire shall be extinguished 312 by means of fire extinguisher provided. The TPC shall be informed immediately of the nature of the fire and the extent to which it has affected supply. 3.2.2. If any unauthorised person notices a fire on or adjacent to traction electrical equipment, he shall make no attempt to extinguish the fire but shall report the occurrence to the TPC by means of emergency telephone or to the nearest Station Master immediately. In the event of a Gangmate noticing fire on or adjacent to traction electrical equipment, he shall in addition, inform any passing train or trolley. If there be more than one Gangmate, the occurrence shall be reported to the Station Master on either side. The Station Master on receipt of such information shall immediately inform the TPC. The TPC shall arrange for fire extinguisher in accordance with these rules. If necessary the Station Master should prevent the movement of trains towards the affected section. 3.3.1. In the event of fire on an electric engine, the Loco Pilot shall immediately switch off the circuit breaker and lower the pantograph. The train shall then be brought to a stop at once. 3.3.2. After cutting off electric supply to the affected circuits, the Loco Pilot shall take necessary action to put out the fire. 3.3.3. If fire cannot be extinguished by the above means, the Loco Pilot shall advise the TPC through the emergency telephone to arrange for the affected section of the overhead equipment to be made dead. 3.3.4.

Fire extinguishers of an approved type for use on electrical fires shall be provided on each electric engine and the Loco Pilot shall make himself familiar with the location and use of these extinguishers. During periodical inspection of a locomotive, the extinguisher shall be examined by the locomotive inspection staff. 3.4. Ordinary fire extinguishers or water from a hosepipe or bucket shall on no account be used to extinguish fires on live electrical equipment. If the services of the fire brigade are required, the brigade shall not be allowed to commence operations until all electrical equipment in the vicinity of the fire has been made dead. 3.5. Fire extinguishers, which have been used, shall be replaced or recharged with the least delay. 3.6. Sand-bins are provided at supply control posts, stations and signal cabins. The supervisory official in-charge shall ensure that the sand is kept dry and clear of rubbish and is not used for any other purpose. 4. Precaution to be taken by staff. 4.1.1. Measuring tapes of all kinds, tools and metal articles, (such as paint pots, oil cans, metal bars) shall not be used where they can be lifted or be dropped or be carried by the wind on to overhead equipment when such overhead equipment is live. 4.1.2. Where overhead equipment for two or more tracks is supported on one structure and work has to be done on the overhead equipment of one track while the overhead equipment of adjacent tracks are live, access to the overhead equipment to be worked shall be by ladders, trestles or similar means but not by the supporting structures. Staff shall not, in any circumstances, walk or climb across live overhead equipment by means of the supporting bridge to gain access to the overhead equipment to be worked on. 4.2.1 Railway staff when required to carry out working on service, buildings and structures in proximity to overhead equipments shall exercise special care to ensure that tools, measuring tapes, materials etc., are not placed in a position where they are likely to fall, or make contact with electrical equipments. 4.2.2. Wherever such work has to be carried out under conditions which involve risk to the workmen or other persons, arrangements shall be made for authorised overhead equipment staff not below the rank of ATFO to be present, who shall take such precautions as may be necessary for the safety of the persons concerned. 4.3.1. A working party shall not commence or carryout any work on or adjacent to overhead equipment involving danger to trains or traffic without the consent of the DEE/Tr.D, or the AEE/Tr. D. 313 4.3.2. No person shall disturb the overhead equipment or carryout bonding or other work in such a way as to obstruct the line necessitating the showing of danger signals. 4.3.2.1. Until such signals have been shown, and 4.3.2.2. If within the station limits, until he has also obtained the written permission of the Station Master and all necessary signals have been placed in the ‘on’ position. 4.3.3. When such work is to be undertaken, the traction official responsible for the work shall advise the Station Master/Station Masters concerned and arrange for showing the necessary danger signals. 4.3.4. When defects are noticed on overhead equipment which are likely to cause damage to pantograph or emergency repairs are being effected to overhead equipment and it is not possible to convey the information to the Station Master/Station Masters concerned to enable them to issue Caution Orders, the line or lines shall be protected in accordance with Rule 15.09 and SRs thereto. 4.4.1. Every member of the staff shall provide for his own protection independent of every other member, except when one is assisting the other in which case, the person in-charge of the work is responsible for the proper protection of himself and his assistants. 4.4.2. Delay or inconvenience to traffic shall not be accepted as an excuse for a man not taking reasonable precautions to protect himself. 4.5.1. No person other than overhead equipment staff climb or work on any permit-to-work card, work shall not be carried out nor shall anything be affixed to any structure without the written permission of the DEE/Tr.D. (See SR.17.04.1.). 4.5.2. Before the work is commenced on a structure supporting overhead equipment, the limits of the danger zone/zones shall be defined by means of a red disc by day and red lamp by night which shall be placed in a suitable position. 4.5.3. When work is to be carried out in the danger zone of structure after the overhead equipment is made dead, no staff other than the person authorised to test and earth the overhead equipment shall attempt to climb the structure, until he has personally received definite instructions to climb the structure from the persons in charge of the working party and no message or signal other than these instructions is permissible. 4.5.4. The instructions may be conveyed from the person in charge of the party to workmen by another person, and such a person shall be individually deputed as a messenger by the person in-charge of the party and shall be of a rank not inferior to Lineman. 4.5.5. All persons deputed in para 4.5.4. to convey instructions to workmen shall be made known to the workmen in advance and the workmen shall be advised that orders regarding the climbing of structures shall on no account be accepted from any person other than those deputed. 4.5.6. The person in charge or the person deputed under para 4.5.4 shall, before instructing his men to climb a structure, explain which section of overhead equipment is dead and which section is live and which parts of the structures are safe to work upon. The person in charge or the person deputed under para 4.5.4 shall satisfy himself that his explanation is clearly understood by all the workmen whom he has instructed to climb the structure. 4.5.7. It shall be the responsibility of every person conveying instructions to climb structures to see that the danger discs or lamps are correctly fixed before the work is commenced. 4.5.8. On the structures spanning multiple tracks, where work is being carried out adjacent to one or more sections of overhead equipment the person in-charge shall ensure, before any of the line or lines are made live on completion of work that all men and materials adjacent to the line or lines have been withdrawn from the danger zone, and if work is to continue on other parts of the structures, the danger discs or lamps have been shifted to indicate the changed danger zone. 4.5.9. The special attention of persons in charge of painting of structures is directed to this rule. 4.6. Instructions given in SR 17.05.5 shall be observed whenever excavation is carried out in the electrified area. 314 4.7. Notice shall be given to the electrical department before changing worn out rails to enable copper bonds to be removed and the rail joints properly rebounded after the completion of the work. Whenever any work is carried out on the permanent way, the track bonding Chargeman-in-charge shall personally inspect the track to assure himself that the continuity of the rail-return is maintained in good order. 4.8. Before any repair or alteration to the overhead equipment is commenced, the Chargeman shall arrange for power to be cut off from the equipment concerned after consulting the TPC. He shall then make sure that the line is dead by testing, following the procedure prescribed by competent authority. 4.9. The Chargeman shall then fix two earthing connections between the line and the structure one on each side of the section of the line where the actual work is being carried out and shall not remove it until the work on the line is completed and all workmen are clear of danger. 4.10. Only after a ‘permit-to-work’ has been received and overhead equipment has been correctly earthed portions of track structure for a distance of less than 2 metres from any live equipment may be scrapped, cleaned or painted. Other portions of the structures of overhead equipment may be cleaned and painted while the overhead lines are live, unless special conditions at site render it unsafe or inadvisable, in which case the work shall only be done after making the equipment dead and earthed. 5.1. When excavations are being made adjacent to tracks and cable routes in an electrified area, adequate precautions shall be taken for the safety of the staff and to avoid damage to underground cables and rail bonds. 5.2. Markers are placed wherever possible, along the cable alignment and diagrams are available indicating generally the position of buried cables. Excavation shall not be undertaken in the vicinity of cable routes until the exact position of the cables has been ascertained and representative of the department concerned is present. This is applicable to cables of P&T department also. 5.3. If circumstances make it imperative that the work has to be undertaken without sufficient notice, the AEE/Tr. D and ASTE concerned shall be informed by a message for arranging staff to be present. 5.4. No staff shall be allowed to work on any portion of a signal post or its fittings falling within a distance of 2 metres from 25 KV live conductor or a metal part electrically connected to this conductor unless such portion is protected with an iron screen. If due to any reason, the protective iron screening is not provided, the railway staff shall not undertake any work on those portions of the signal or its fittings falling within 2 metre zone from a 25 KV live part unless the power has been switched off and a ‘permit to work’ has been obtained. To draw the attention of the signal staff in such cases, a caution board 9” X 8” indicating “Caution” in Hindi, English and the regional language in white letters with red background shall be provided on the signal post at a height of 10 ft. above the rail level. The Inspectors of the Signal department and Station Masters shall explain these instructions to the staff working under them and ensure that they are correctly understood. 5.5. Induced voltages may appear in signalling and telecom circuits, where the parallelism in lengths of track is important. It may be noted that even when there is no induced voltage in circuit at the time of starting the work, precautionary measures listed below shall be taken, as induced voltage may appear at any time on account of sudden short circuit in the traction overhead equipment. It is also to be noted that in some circuits with earth connection, contact with which may normally be without danger, in case of break of the circuit an induced voltage may appear between two parts created by the break. Consequently each time staff have to work on S &T circuits along with 25 KVAC electrified line, they must take the following precautionary measures. 5.5.1. They should as a general rule wear rubber gloves and use tools with insulated handles. 315 5.5.2. When the work to be done is meticulous and rubber gloves cannot be used, special precautions should be taken by splitting the circuit into the section or earthing them. In special cases both steps should be taken simultaneously. 5.6.1. All overhead line staff, when on patrol, shall watch the pantographs of passing electric rolling stock and if any defects are noticed, they shall report to the TPC through the emergency telephone circuit or any other telephone, if emergency telephone circuit is not available, giving full particulars including the number of the electric rolling stock, the location of the defect and the time when defect was noticed. 5.6.2. The TPC shall communicate reports on a defective pantograph to the TLC who shall arrange to have the electric rolling stock stopped as soon as possible, for examination of the defective pantograph. 5.7. TFO/OHE shall be responsible for the proper and efficient maintenance of all breakdown equipment, wiring trains, tower wagons, breakdown Lorries, etc., so that they are always in a state of good repair. He shall ensure that they are equipped with full quantities of stores and spare parts as per approved inventory. All tools, tackles, straining, screw clamps, ropes and ladders shall be maintained in good condition and ready for use at all times. 5.8. The staff concerned shall ensure that the equipment not in immediate use is always ready for service, except such equipments as may be under repair or overhaul. 17.06. Alterations to track.–– Before any alteration to alignment or level of electrified tracks is commenced, due notice shall be given to those responsible for the overhead equipment so that the overhead equipment may be adjusted to conform to the new conditions. SR.17.06.1.1. Before any slewing alteration to super-elevation or level of tracks from the permissible parameters is done, notice shall be given to the DEE/Tr.D to enable him to arrange for adjustment of over head equipment to conform to the new conditions if necessary. Such work shall be included in the weekly programme detailed in SR.17.04.8. 1.2 It shall be ensured that the level of rail under foot-over bridges, road-over bridges, tunnels and other over line structures does not exceed the level marked under such structures. 2.1 All minor alterations to overhead equipment whether permanent or otherwise shall be reported to the TPC immediately by telephone and to the DEE/Tr.D or the AEE/Tr.D in writing. 2.2. Major alterations affecting the existing disposition of any section of overhead equipment shall not be made unless sanctioned by the DEE/Tr.D. 3.1. When working on overhead equipment, all staff shall ensure that the wires are not deflected, which may foul pantographs of electric rolling stock passing on other lines by steady arm tubes of any other part of the overhead equipment. 3.2. When the overhead equipment is slewed either temporarily or permanently, the persons in-charge shall ensure that section insulators, jumpers and other fittings do not foul the pantographs of electric rolling stock passing on the other lines or any other parts of the overhead equipment. 4.1. Whenever any work on track, which is likely to affect rail bonds, ‘track circuit bond’ is undertaken by permanent way staff, adequate notice shall be given to the TFO/OHE and Signal Inspector where track circuits are involved to enable him to arrange bonding staff for removal and replacement of bonds. 4.2. Bonding staff when working with a PWI shall work under his instructions and PWI shall be responsible for the safety of the track and the staff working under him. 316 17.07. Tripping of circuit breakers of locomotives and electrical multiple units at neutral sections.–– Unless otherwise allowed by special instructions, the Loco Pilot of the locomotive or electrical multiple unit shall coast through the neutral section, duly switching off power. Necessary indication boards to this effect shall be provided to guide the Loco Pilot to switch off and switch on power. S.R.17.07.1. Warning Boards for neutral sections. Warning Boards as per figures 1 & 2 shown in the end of this SR, shall be fixed on the OHE masts in rear of neutral sections at a distance of 500 metres and 250 metres respectively. Similarly the location at which the power has to be switched off and on shall be indicated by boards to be fixed on the OHE masts as per figures 3 & 4 respectively. No Loco Pilot shall pass the neutral section between the warning boards, as per figures 3 & 4, with power on. In order to negotiate the neutral section without stalling, the Loco Pilot shall approach it, at a speed not less than 30 KMPH. The Loco Pilot or the Assistant Loco Pilot as the case may be shall call out to each other, all the permanent/temporary display boards in the section, in the same manner as they call out the aspects of fixed signals and engineering indicators. 2. Warning Boards for Temporary Neutral Sections. Due to exigency of imposition of speed restrictions of less than 30 KMPH, within one Kilometre on either side of the neutral section, emergency feeding arrangement in case of sub-station failures etc., it may be necessary to provide a temporary neutral section, where the Loco Pilots would have to lower and raise pantographs during its negotiation. Warning Boards as per figures 1 & 2 shall be fixed on the OHE masts at a distance of 500 metres and 250 metres respectively, in rear of the temporary neutral section. Similarly, the location at which the pantographs would have to be lowered and raised shall be indicated by boards as per the figures 5 & 6. Such warning boards shall be provided only if temporary neutral section working is to be continued for a duration of more than 24 hours. All Loco Pilots shall be given Caution Order at station/notice station concerned duly indicating the locations at which the pantograph has to be lowered and raised. Loco Pilots of all trains shall approach the temporary neutral section at a speed of not less than 30 KMPH to negotiate it without stalling. 317 3. Programmed speed restrictions at Neutral Sections. Whenever speed restrictions of less than 30 KMPH on either side of the neutral section (for programmed works) is necessary, such speed restrictions shall not be imposed until the Sr.DEN/DEN concerned has made arrangements with the Sr.DEE/DEE(Tr.D) for temporary energisation of the neutral section. After the neutral section is provided with necessary warning boards, the Tr.D staff shall authorise the Station Master/SCOR to permit movement of electric train/EMU into the section, duly exchanging PNs and also after informing TPC that the neutral section has been jumpered and temporary section provided, duly specifying the location. No electric train/EMU shall be permitted to enter the section with speed restriction of less than 30 KMPH. Unless the Station Master/SCOR has received this authorisation from Tr.D staff, under such conditions, the Loco Pilots of all electric trains/EMUs shall be issued with Caution Orders at stations/notice stations concerned, permitting them to pass the neutral section with power on and also indicating to them the location of temporary neutral section, where the pantographs have to be lowered and raised. 4. Emergency speed restriction at neutral sections. Whenever emergency speed restrictions of less than 30 KMPH are required to be enforced within one KM on either side of the neutral section, the permanent way staff shall immediately arrange to protect the affected section on either side and take all steps to bring to halt any train in rear of neutral section. The PWI shall also inform the nearest Station Master regarding imposition of speed restriction. The Station Master shall inform the Station Master at the other end of the neutral section, the SCOR and TPC. The SCOR and Station Masters at either end of the neutral section shall not permit the entry of any electric train/EMU into the section until an advice has been received from the TPC. The TPC shall make immediate arrangements for energising the neutral section and provision of a temporary neutral section. After this has been completed, movement of electric trains/EMUs shall be permitted in accordance with S. R. 17.07.3. The Tr.D. official, who has jumpered the neutral section, shall issue a Caution Order to the Loco Pilot of the train, if any which might have been stopped in rear of the neutral section, advising him that he can pass the neutral section, with power on and also informing him, if necessary, the locations at which he has, to lower and raise pantograph at the temporary neutral section. 17.08. Tower wagon.— The rules for the movement and working of tower wagons shall be laid down by special instructions. S.R.17.08.1.1. In case of breakdown of overhead equipment, the SCOR, on request from the TPC, shall arrange for quick passage of the tower wagons /OHE wiring trains to the site of breakdown. The movement of tower wagons shall be governed by all the rules governing movement of trains. 1.2. Tower wagons shall not be worked on running lines unless a Driver or an official holding a competency certificate for this purpose is on the tower wagon and is in-charge of its movements. The certificate of competency shall be issued by DEE/Tr.D after a written, oral and practical test in the relevant rules. 1.3.1. Ladder trollies shall be considered as lorries and when placed on the line shall always be accompanied by atleast 4 selected men who can easily lift them off the track. 318 1.3.2. These trollies shall not be used for the carriage of electrical or other heavy materials. The running of ladder trollies shall be governed by Rules 15.18 to 15.27 and SRs thereunder. 1.3.3 These ladder trollies along with ladders will move on the track under protection as laid down in Rule 15.09 and SRs thereunder both outside and within station limits. 1.3.4. The working of ladder trollies will be supervised by a supervisor not below the rank of Electrical Chargeman specially authorised for the purpose. It shall be the responsibility of the supervisor concerned to ensure that Caution Orders and various other advices required as laid down in Rule 15.09 and SRs thereto, are issued to all the station staff concerned well in time. The supervisor will also ensure that these ladder trollies and ladders are removed from the track in time to avoid detention to trains. After the trollies are removed, they should also ensure that they are properly secured without any infringement of moving dimensions, before allowing a train to pass. 1.3.5. While issuing Caution Orders and advices, specific mention shall be made regarding the type of precautions, the exact kilometreage between which the work is in operation and the block section concerned, so that the Loco Pilots may keep a sharp lookout and be prepared to stop short of obstruction, if required. 1.3.6. At places where the trollies are lifted off the track and kept in trolley refuges, special care shall be taken to ensure that these trollies do not endanger safety of moving trains. 1.4. In the event of a minor defect occurring on the overhead wires which does not necessitate the immediate isolation of the section, Station Masters should stop all trains outside the affected section and issue a Caution Order to the Loco Pilot to proceed cautiously until he is clear of the section, or until it is safe for him to proceed at normal speed. Such occurrences should be immediately reported to the TPC who will arrange to inform the maintenance party and to proceed with the repairs as soon as possible. 1.5.1. Supervisory officials in-charge of maintenance of overhead equipment shall carefully plan their work in such a way that under normal circumstances, train service is not affected in any way, where the nature of the maintenance work is such that train movement is likely to be affected, the TFO/OHE shall give prior intimation to the DEE/Tr.D who will arrange for traffic working rules to be issued to facilitate the execution of the work. 1.5.2. Whenever any section of the overhead equipment is to be made dead for the purpose of maintenance work, the Chargeman in-charge of the section will give intimation to the TPC at the earliest possible time, specifying the section where shut-down is required. The TPC shall then intimate the Chargeman the time and permissible duration of the shut-down. The Chargeman is responsible for regulation of work so that permissible duration is not exceeded. If for any reason the period of shut-down is required to be extended, the TPC should be advised in good time. 1.5.3. Where written messages are not exchanged, shut-down will be effected by exchanging messages over the telephone, using the PN. The official in actual charge of the maintenance work shall in person exchange messages with TPC. No one below the rank of Linesman is authorised to exchange such messages. 1.5.4. Shut-down on any section of overhead equipment (except at location where Electric locos are stabled for examination), shall be effected only after the SCOR has been informed by the TPC and has agreed to shutdown except in case of emergency. When train movement has to be blocked over any crossover road or section of line for the purpose of effecting shut-down, the TPC shall advise the CHC, as to what train movements are to be blocked during the period of shut-down. The CHC shall advise the Station Masters of train movements as required. The Station Master shall block train movements as required and advise CHC by message. The CHC shall advise the TPC by message that the movements have been blocked. 1.5.5. After the train movements are blocked as required and after switching of power from the section, the TPC shall inform the Chargeman and other official in charge of the work by message that power has been switched off and work may be commenced. On completion of 319 the work, the official in-charge of the work shall advice the TPC by message that the work has been completed. The TPC shall then restore power on the section and inform the CHC by message that normal traffic may be resumed. 1.5.6. Operation of the overhead switch isolators at stations for the purpose of effecting shut- down shall be done on instructions from TPC by authorised person available for the purpose. 1.5.7. Before commencing work on the overhead equipment, the Chargeman shall test lines for supply with the method prescribed by competent authority and fix two earthing connections on the line, one on either side of the section of line where work is to be carried out; the earthing connections shall be of approved type and of adequate cross-sectional area. The earthing shall not be removed until all work has been completed and all men are clear of the line. 1.5.8. In case of break down of overhead equipment, the official in-charge of the repair work shall inform TPC as to what sections of line are to be made dead to facilitate the work. Care shall be taken when effecting shutdown to ensure that power is not cut off over those sections in which train services may be maintained without hindrance to the repair work. The procedure for cutting off power and for blocking train movements and for restoration of power shall be the same as in the case of shut-down for maintenance work. 1.5.9. On completion of the repair work, the official in-charge of the repairs shall advise whether normal traffic may be resumed or whether any speed restrictions are to be imposed. If a speed restriction is to be imposed, the official concerned shall advise in writing to the Station Master and shall also inform the TPC. The TPC shall clearly state so in his advice to the CHC, who will ensure that these instructions are conveyed to the Station Master concerned. When the speed restriction is to be removed or relaxed, supervisory official shall advise in writing to the Station Master and also inform the TPC who shall then convey the message to CHC. 1.5.10.1. When loads which exceed the prescribed standard moving dimensions are to pass through the electrified sections, the CHC shall give atleast 48 hours prior notice to the TFO/OHE & the TPC. 1.5.10.2. When shut-down is to be effected on any section or sections of the line for the passage of oversized consignments, the same procedure as laid down in para 1.5.4 shall be followed. The authorised person receiving the shut-down message from the TPC shall issue Permit-to-work to the Guard of the train with the oversized consignment, for each section of the line on which power has been shut-down. The Guard shall not allow the train to enter this section until the Permit-to-work is received by him. Before issuing the Permit-to-work, the authorised person will test the line but it is not necessary to earth the line. When the train has to pass through two or more feeding sections, each section shall be tested before the train enters the section. 1.5.10.3. An additional authorised person should be deputed to travel on the engine, to test the line for power supply at each feeding section. The Station Master at the starting point shall advise the Loco Pilot in writing to follow the instructions of the authorised person, to stop the train as and when required for the purpose of testing the line for power supply. 1.5.10.4. The Permit-to-work shall be returned by the Guard of the train duly signed, to the authorised person, when the train has passed out of the section concerned. The authorised person shall then issue a message to the TPC that the line is clear. 1.5.10.5. No work may be carried out in the vicinity that is within 2 metres of live overhead equipment, till a Permit-to-work has been obtained as laid down in SR.17.04. Atleast 48 hours prior notice shall be given to the TFO/OHE, who shall depute an authorised person to arrange for the shut-down. The authorised person shall effect the shut-down by following the procedure laid down in Para 1.5 and shall issue a Permit to work to the supervisory official in-charge of the work. Before issuing the Permit-to-work the authorised person shall test the line for supply and earth the lines. The Permit-to-work shall be retained by the supervisory official in-charge of the work and on completion of the work, he shall return the 320  ‘permit-to-work’ duly certified that the work has been completed and all men are clear of the live equipment. The authorised person shall then remove the earthings and issue a message to the TPC that power may be restored on the line. 1.5.10.6.1. Crow nests or other stray wires, in the vicinity of live overhead equipments, may be removed only after power has been switched off from the line. Such work may only be done, with the aid of insulated hooks of approved type, taking care not to make contact with the over-head wires or insulators. Under these circumstances, it is not necessary to test and earth the lines, after it is certified by the TPC. 1.5.10.6.2. When a nest or stray wire is to be removed, a person not below the rank of a Lineman, shall inform the TPC over the telephone that power is required to be switched off, clearly stating the location where the work has to be done. The TPC shall then switch off power from the section, after instructing the SCOR to stop train movements which are likely to result in making the line live and ensuring that these instructions have been conveyed to the Station Masters concerned and have been acknowledged by them under exchange of PNs. The TPC shall then inform the Lineman that the power has been switched off from the line. The Lineman shall arrange to remove the crow nest or stray wire as expeditiously as possible and when this has been done, inform the TPC without delay that the work has been completed and power may be restored on the line. 1.5.10.6.3. The TPC shall make detailed entries in the log sheet of all particulars relating to the shutdown. 1.5.10.7.1. Due to a break of overhead equipment or for any other reason, when it becomes necessary to stop train movements urgently over a section of line or over a cross-over road, the TPC shall inform the SCOR. 2. Tower wagon Drivers. A tower wagon Driver should undergo course of training and tests indicated below, before the certificate of competency is issued to him:- 2.1. A training in G&SR in the ZRTI/MLY or other approved establishment followed by a written and practical test conducted by the ZRTI/MLY. 2.2. A practical test by CTFO/OHE to see if the employee is fully conversant with the engine and running gear of the tower wagon, as well as the details of maintenance he is expected to carry out. 2.3.

A period of practical training for 2 months in the actual driving of the tower wagon under the supervison of a qualified tower wagon Driver at the end of which a driving test will be taken by DEE/Tr.D. 2.5. Prescribed medical examination. 3. Competency Certificate:- Tower wagon Driver will be given a competency certificate by DEE/Tr.D after written test on form TR-4. Form No.TR-4 CERTIFICATE OF COMPETENCY South Central Railway Electrical Department. Number ……………………………………….. (for tower wagon Drivers) Shri ……………………………………… is authorised to drive tower wagons in the section between …………………………. and ………………. duly observing all the safety rules and standing instructions. His written declaration *dated ……………….. that he is fully familiar with the signals in the above section has been noted while issuing this certificate. Date: DEE/Tr.D 321 This declaration must be countersigned by driving Inspector and personally scrutinized by the officer, before issue of the certificate. The driving Inspector before countersigning the declaration, shall orally examine the employee for his knowledge of the road. 4. Maintenance. Tower wagons perform a key role in the maintenance of OHE and for attending the breakdowns. The satisfactory upkeep of tower wagons is, therefore, of utmost importance. It will be the direct responsibility of ATFO/OHE to ensure that the tower wagon under his control is maintained satisfactorily and is always available for attending to OHE and for use in the event of breakdowns. Each tower wagon should carry necessary tools for maintenance of OHE and attending to breakdowns such as tackles, straining screws, clamps, ropes, a minimum of two ladders as well as adequate stock of insulators, contact and catenary wires and other OHE fittings. An approved list of tools and equipment to be carried in each tower wagon should be issued by DEE/Tr.D. It will be the responsibility of ATFO/OHE to ensure that tools and equipment as per the approved list are always available on the tower wagon. A monthly mechanical inspection of the bogie and running gear of each tower wagon shall be done by a nominated TXR of the mechanical department, headquartered close to the OHE depot, where the tower wagon is normally stabled. For each tower wagon on a zonal railway, the TXR responsible for monthly mechanical inspection will be nominated and a joint circular to this effect must be issued by CME and CEE. The ATFO/OHE in-charge of the tower wagon will advise the TXR concerned the date on which the tower wagon is required to be attended for monthly inspection and running repairs. Such advice shall be given 48 hours in advance. It will be the responsibility of the ATFO/OHE to ensure that this monthly advice is issued regularly and the tower wagon is offered for inspection and attended to every month. The TXR will arrange for examination of bogie, running gear, under frame, under gear fittings and axle boxes only, in accordance with IRCA rules Part III. He will also arrange for stenciling the date of monthly examination on the sole bar of the tower wagon. Depending on the intensity of usage of the tower wagon in each railway, the CEE and CME should jointly decide the interval at which the tower wagons are required to be given POH. Such POH will be done in the nominated C&W workshop of the zonal railway. The day to day maintenance of the diesel engines and driving gear of the tower wagons will be the responsibility of the ATFO/OHE concerned. The tower wagon drivers should carryout the daily maintenance. Specialized staff conversant with the maintenance and overhaul of diesel engines and driving gear should be available on each division for attending to the monthly and six monthly maintenance schedule of the diesel engines and driving gear. Depending on the work load, two or three divisions may be grouped together for the purpose of posting such specialized staff if it is convenient. Taking into account the total number of tower wagons and the need to relieve tower wagons for the purpose of POH etc., in each zonal railway, one or more spare tower wagons may be provided as necessary. 5. Rules for operating tower wagon. 5.1. No tower wagon may be operated by anyone unless he is authorised to do so after he has been examined for his knowledge of the rules prescribed. 5.2. Scope:- The following rules shall govern the wor
