Acknowledgement of Signals – (a) Each signal received shall be acknowledged by sending the authorized beats in acknowledgement. (b) No signal shall be acknowledged until it is clearly understood. (c) A signal shall not be deemed to be complete until it is acknowledged. (d) Should the station to which a signal is sent fails to reply, the signal shall be repeated at intervals of not less than 20 seconds until the reply is received. 5.11. Explanation and application of Bell Codes – (1) “Call Attention”- This signal shall be sent and acknowledged before sending any other signal. The only exception to this rule, is when “Obstruction Danger” signal (six beats) is being sent. In such cases the “Attention” signal shall not precede the “Obstruction Danger” signal and the Station Master receiving the “Obstruction Danger” signal shall immediately acknowledge it by an exact repetition. (2) “Is Line Clear” or “Line Clear inquiry” – This signal is sent when permission to withdraw a Token is required. It shall not be sent unless the “Train out of Section” signal has been received and acknowledged for the last preceding train. The beats describe the class of train for which Line Clear is required. (3) Train entering Section – (a) This signal is sent when a train enters the Block section and shall not be sent until the train has passed the last Stop Signal. Note: In cases, where, due to any reason, there is delay in conveying the “Train entering Section” signal by beats on block instruments or acknowledgement thereof, the time of the train entering the section should also be repeated on the block telephone and an entry made to this effect in the “Remarks” column of the Train Signal Register. (4) “Train out of Section” – (a) This signal is sent when the whole train has arrived complete and the conditions under which Line Clear may be given, have been complied with. (b) “Obstruction removed” – This signal is sent after the “Obstruction Danger” signal when the obstruction has been removed. 75 (5) “Cancel Last Signal” or “Signal given in Error” – This signal is sent when it is required to cancel the previous signal or when the previous signal has to be altered. When used to cancel a “Line Clear” signal (given or received) it shall be confirmed by the exchange of Private Numbers and a record of Private Numbers shall be made in the Train Signal Registers at both station with a brief statement of the reasons for cancellation. (6) “Obstruction Danger” – (a) This signal is sent when it is necessary in consequence of any obstruction or other cause for an approaching train (for which “Line Clear” has already been sent) to be stopped at the Block station in rear. The Station Master sending the “Obstruction Danger” signal shall immediately place all approach signals to the “ON” position. The station Master receiving the “Obstruction Danger” signal shall immediately place all signals to the “ON” position and take all possible measures to stop the train leaving his station. On no account shall the train be allowed to proceed until the “Obstruction Removed” signal has been received from the station which sent the “Obstruction Danger” signal and a new “Line Clear” has been obtained. (b) “Stop and examine Train” – (i) This signal is sent to the Block station in advance when anything unusual is observed on a train passing a station such as – I. Signals of alarm by a passenger II. Goods falling off an open wagon III. Vehicle on fire IV. Hot axle-box V. A carriage door opening outward VI. A goods wagon door open and not fastened or secured or VII. Any other dangerous condition likely to foul or obstruct the railway line or lines. (ii) Station Master and their staff shall observe the condition of vehicles on train passing their stations. In the event of any defect or irregularity, as referred to in subparagraph (I) above, being detected, immediate steps shall be taken to stop the train by showing danger signals. If the train cannot be stopped, the Station Master shall at once send “Stop and Examine Train” signal to the Station Master of the Block station in advance and advise him by telephone why the signal was sent under exchange of Private Numbers. (iii) The Station Master sending the signal shall if he considers it advisable stop a train coming in the opposite direction with a view to ascertaining whether any injury to a passenger or damage to the train has been caused by the train for which the signal was sent. (iv) The Station Master receiving the signal shall acknowledge it immediately and ascertain if the Station Master giving the message considers that the adjacent line or lines is/are likely to be fouled. In 76  case the fouling of adjacent line/lines is considered likely, the station Master receiving the message shall use all available means to stop the train in question and also any train proceeding by adjacent lines likely to be fouled. Till such time as the affected train which was likely to foul adjacent line or lines arrives complete at the station where the message was received, the Station Master, at either end of the block section shall not allow any train by such adjacent lines in either direction. When the affected train has been stopped it shall be carefully examined and dealt with as the occasion may require. (iv) If after examination of the train the reason for the signal is not apparent or there is a likelihood of a passenger having fallen down or some goods or materials having fouled or obstructed the railway lines, trains may be permitted to enter the section by the same or adjacent lines after advising the Loco Pilots of the circumstances and warning them through a Caution Order (Form T/409) to proceed cautiously to the next Block station and to keep a sharp look out for any possible obstruction. Issuing of Caution Order shall be discontinued only when it has been ascertained that the concerned block sections are free from obstructions. (v) If however, the Station Master sending the signal notices signals of alarm by a passenger in the passing train or goods falling off and open wagon or any other dangerous condition likely to have fouled or obstructed the railway line or lines of the section in rear also he shall after taking action as per sub-paragraph (ii) above, use all means available to stop trains, if any, proceeding in the opposite direction towards the Block station in rear by adjacent line and send immediately “Obstruction Danger” Signal to the Station Master of the Block station in rear to stop trains, if any, approaching in the same direction either by the same line or adjacent line. He shall then advise him by telephone why the signal was sent, under exchange of Private Numbers. Thereafter trains may be permitted to enter the section by the same or adjacent lines after advising the Loco Pilots of the circumstances and warning them through a Caution Order (Form T/409) in accordance with the procedure as mentioned in Sub-paragraph (v) above. (c) “Train passed without Tail Lamp or Tail Board” – This signal is sent to the station in advance should a train pass without a Tail-lamp on the last vehicle, which shall be burning by night and the “Train out of Section” signal shall not be sent to the block station in rear and the Token delivered by the train shall not be inserted in the instrument but shall be kept in the custody of the Station Mater until he has heard from the station in advance that the train has been stopped and found to be complete. If the station in advance reports that the train is incomplete, the Block section in rear shall be considered obstructed and the Station Master shall take immediate steps to clear the section. (d) “Train Divided” – This signal is sent if a train parts when leaving a station or if it passes a station in two or more parts. The Station Master receiving 77  the “Train Divided” signal shall take off signals to admit the first portion of the train into the station where it shall be brought to a stand. After ascertaining the number of vehicles that have arrived on the train the Station Master shall advise the station in rear. The “Train out of Section” signal shall not be sent until the Station Master has satisfied himself that no portion of the train has been left in the Block section. (e) “Vehicles running away” – This signal is sent if a vehicle or portion of a train has escaped and is running away or if a train enters the Block section without a Line Clear authority. (i) The Station Master receiving this signal shall keep all signals in the “ON” position but if there is a train in the same Block section running in front of and same direction as the runaway vehicles, the signals shall be taken off to allow the train into the station where it should be stopped. (ii) The facing points shall then be reversed to protect the train standing at the station and all possible measures taken to stop the runaway vehicles. (iii) If the signal is received too late to take the action mentioned above the Station Master shall repeat the signal to the next station towards which the runaway vehicles are proceeding. (7) “Testing Signal” – This signal is used by the Block Maintenance staff to ascertain whether the Block Instruments, etc. are in order and it shall be promptly repeated by Station Master. 5.12. Obtaining token – (a) In the case of a stopping train the “Is Line Clear” Signal shall not be sent until the “Train Entering Section” signal has been received. (b) In the case of a train booked to run through the “Is Line Clear” signal may be sent before the “Train Entering Section” signal is received but not earlier than five minutes before the train in question is booked to leave the station in rear. 5.13. Delivery of token – (a) The Station Master is responsible for seeing that the proper Token for the section into which a train is proceeding is given to the Loco Pilot. (b) When an incoming Token is received, the Station Master on duty shall examine it and satisfy himself that it is the correct Token for the particular Block section and shall enter the number of the Token in the Train Signalling Register before inserting it in the instrument. (c) Under no circumstances shall a Token be handed over to the Loco Pilot unless it has been obtained from the instrument in accordance with the rules laid down. 78  (d) The Station Master shall be responsible for seeing that every member of his staff through whose hands Tokens may have to pass, is acquainted with the distinguishing features of the Tokens of the adjoining sections. 5.14. Canceling Line Clear. – (a) If, after “Line Clear” has been received and a token/tablet has been extracted, it becomes necessary to cancel the “Line Clear”, the Token shall be replaced in the instrument and the Operating Handle returned to its normal position in accordance with the sequence of operations laid down for signalling trains. (b) Whenever a Token/tablet is returned to the instrument from which it was extracted, Private Numbers shall be exchanged and a record made in the Train Signal Registers at both stations with a brief remark as to the circumstances of the case. (c) If a Token/tablet has to be returned to the instrument from which it has been extracted owing to the return of the Train, as in the case of a Divisional Material Train the Station Master shall, after having returned the Token send the “Train out of Section” signal and then proceed to turn the Operating Handle to its normal position in accordance with the sequence of operations laid down for signaling trains. 5.15. Refusing Line Clear – When a Station Master is asked for a Private Numbers for a train but desires precedence to be given to a more important train to proceed from his station he shall state the fact and a record of the transaction shall be entered in the Train Signal Registers at both stations. 5.16. Authority to proceed – (a) No train shall enter a Block section from a station where Electrical Block ball/token/tablet Instruments are in use without a Token/tablet being in possession of the Loco Pilot, except in the case of failure of the token/tablet Instrument or in case of an engine or a train proceeding to assist a disabled train in which case the Loco Pilot shall be given a written authority. (b) The Loco Pilot shall satisfy himself that the Token/tablet handed to him applies to the section he is about to enter. He shall keep the Token/tablet in his possession until he reaches the end of the section when he shall make it over in the authorized manner except in the following circumstances – (i) When a train disabled and a portion of the train is left in the section in charge of the Guard, the Loco Pilot before proceeding shall hand over the Token/tablet to the Guard and obtain from him receipt for it. (ii) When a train parting occurs and a portion of the train is left in the section, the Loco Pilot shall not deliver the Token on arrival at the station but retain it in his possession until he has brought-in the rear portion of his train. (c) Whenever it may be necessary to give a Loco Pilot any special instructions respecting the road or any other circumstances demanding caution, the Token/tablet shall be supplemented by a Caution Order on Form T/409. 79 5.17. Wrong Token/Tablet delivered to Loco Pilot – When an incorrect Token/Tablet is delivered to a Loco Pilot he shall carefully note the number and then return it to the issuing Station Master who shall grant a receipt for it. The Loco Pilot shall report the case in writing at the end of the trip. 5.18. Exchange of Tokens by Non-stopping trains – (a) The outgoing Token shall be made over to the Loco Pilot by means of a loop at the Line Clear post.

At night a torch light shall be displayed at the Line Clear post and at the place where the incoming Token is to be dropped. (b) Should a Loco Pilot over carry a Token to a station beyond the section to which it applies he shall hand it over to the Station Master on duty on arrival of his train at that station and obtain a receipt for the same. 5.19. Exchange of tokens by stopping trains – (a) The Loco Pilot shall deliver the loop with Pouch and Token to the station group-D staff waiting to receive it on the platform or on that side of the line where he can remain with safety. At night the station group-D staff shall be provided with a lighted torch. If Loco Pilot finds that there is no station group-D staff waiting to receive the incoming Token he shall keep it in his possession until it is sent for. (b) the outgoing Token shall be handed over to the Loco Pilot by a group-D staff. (c) When a train is worked by more than one engine or two or more light engines are coupled together, the token shall be carried by the Loco Pilot of the leading engine. 5.20. Transferring Tokens – When a Station Master observes that Tokens are nearly exhausted at his station he shall advise the Block Signal Inspector of the section by message as follows – “Tokens short on the Up/Down side…..” The Block signal Inspector (supervisory) of the section shall at once arrange for the transfer of Tokens. (a) When removing tokens from an instrument the member of the Signalling staff who is authorized to carry out this duty shall show the Tokens removed to the Station Master and make the following entry in the Token Register which shall be signed by the Station Master on duty. No. of Tokens…………………………. For section …………………………. 80  Time removed …………………………. Position of Operating Handle …………………………. Date …………………………...………………………….........

On sections where Traffic Control is in operation the Controller shall also be advised. (ii) record the failure and time in the Train Signal Register. (b) The Station Master receiving advice that Token/Tablet working is suspended shall acknowledge the message by repeating it and make a record in his Train Signal Register. (c) When the failure has been rectified it shall be recorded in the Train Signal Register and the entry signed by the Station Master and the member of the Signalling staff who rectified the failure. 81 (d) Token/Tablet working shall not be resumed while there is a train in the Block Section. (e) Before resuming Token/Tablet working the Station Master at the stations where the instrument was defective shall intimate regarding resumption of normal working to the Station Master at the other end of the section and obtain his acknowledgement. (f) After Token working has been resumed the Station Master shall - (i) Intimate signal Inspector (Supervisory) Signal Inspector & the Signal & Interlocking Maintainer (Electrical) of the section (Omitting the person) who rectified the failure. Record the time Token working was resumed in his Train Signal Register. (g) The Station Master receiving advice that Token working has been resumed shall acknowledge the message by repeating it and make a record in his Train Signal Register. (h) If a lost Token is found after a failure message has been sent, but before the arrival of the Signalling staff and even if trains have been passed meanwhile on Paper Line Clears, the instruments shall be restored by the Station Master personally, who shall provided that the Block Section is clear, advise the Station Master at the other end of the section as follows :- “No……………..Token No……………….found. Propose to restore Token Instrument.” (i) The Station Master receiving the advice shall reply as follows – “No……………..Your No……………….Restore your instrument and let me restore mine. Both station Masters shall then proceed to place their instruments in the normal position carrying out the regular sequence of operations and the Station Master who reported the failure shall advise the Signalling staff as follows – Lost Token found. and send a copy of the message by train to the Divisional Railway Manager. (j) If a lost Token is found after the instruments have been restored by the Signalling staff it shall be put in paper cover and kept in the station safe until it can be put into the instrument by the Signalling Inspector to whom the following message shall be sent. “Token No……………………..found.” (k) If a lost token is found at a station to which it does not belong it shall be put into a stout cover and dispatched to the Divisional Railway Manager of the section to which it refers. 82 5.22 I. Failure of Electrical Block and Electrical Speaking Instruments – In the event of failure of the Token/Tablet instruments train shall be passed on Paper Line Clear which may be obtained – (a) by the direct telephone (b) through the Controller in the event of failure of telephone.

(a) All failures of Electrical Block and Electrical speaking Instruments or any electrical signalling apparatus shall be reported to the following persons by message – Divisional Railway Manager Assistant Signal and Tele-communication Engineer SSE (S&T) (Supervisory) or SSE/JE (S&T) of the section Transportation Inspector (Movement) (b) The Station Master shall record details of all failures in the Block Failure Register maintained at his station. (c) When a failure has been rectified, the Signal Inspector or his authorized representative shall certify to that effect in the column provided in the Block Failure Register. 5.23. (i) Should the direct telephone communication also fail all messages for passing trains shall be transmitted through Control telephone. (ii) The Station Master asking line clear from the Station Master at the other end of the block section, will indicate the times of arrival at or departure from his station of the last two trains. Similarly the Station Master, who is granting “Line Clear”, will give to the Station Master asking permission the times of arrival at or departure from his station of the last two preceding trains. (iii) Thereafter line clear shall be asked and given under exchange of Private Numbers. (iv) Section Controller should ensure that the Station Master at either end shall, before asking and granting “Line Clear” repeat the arrival and departure timings of the last two preceding trains. He should also check correctness of the particulars to ensure that correct stations are contacted and record on his control chart the Private Numbers exchanged between the stations concerned. The Station Masters concerned shall however be entirely responsible for safety of trains. Note : On A.C. electrified sections due to poor audibility of direct speech between two stations on control telephone system the “Line Clear” messages shall not be conveyed direct between the stations but will instead be exchanged 83  through the Controller on duty. A record of Private Numbers shall be kept by the stations and the Controller. 5.24. Train Signal Register – (a) The exact time at which all signals are sent or received and also Private Numbers when used shall be entered immediately after being acknowledged in the Train Signal Register by the Station Master on duty. (b) The entries shall be in ink and no eraser shall be made in any circumstances. If an incorrect entry is made, a line shall be drawn lightly through it and the correction made above it and initialed so that the original entry may be clearly seen. (c) The Train Signal Register is on no account to be taken out of the Block Cabin. It shall be examined and signed daily by the Station Master. The only exception to this rule is when an accident has occurred under which circumstances the register may be removed for safe custody by the Station Master or by an Inspector after a new register has been brought into use. (d) The number of every Token extracted from and inserted into the instrument shall be entered in the Train Signal Register. (e) The Train Signal Register shall also be scrutinized by the Transportation Inspector (Movement), who shall place his initials against such portions of the register as he has examined. 5.25. Station Masters changing duty – (a) The Station Master who makes any entry for a train shall continue on duty until the entries affecting that train are completed. By this it shall be understood that the man who gives permission for the train to enter the Block Section shall remain on duty till the train has arrived and the “Train Out of Section” signal has been given and acknowledged. The man who receives permission for the train to enter the Block Section shall remain on duty till the “Train Out of Section” signal has been received and acknowledged. (b) In the case of train working in the Block Section and in exceptional circumstances like accidents, engine failures, OHE failures etc. where abnormal delay of the train is apprehended, Sub-rule (a) need not be observed, but the fact shall be recorded in the remarks column of the Train Signal Register by the Station Master going off duty, who shall be responsible for seeing that the entry is initialed by the Station Master coming on duty. (c) A line shall be drawn across the Train Signal Register whenever Station Master changes duty and the Station Master going off duty shall sign his name legibly and enter the time above the line.
