Proceeding to Site of Accident: 1.1. On receipt of information of the occurrence of an accident, the SSE/JE/Signal shall proceed by the Quickest-available means to the scene of the accident, with staff and tools and portable control telephones and establish immediate communication with control. 1.2. He shall make a special note of the exact time of the accident, besides other important details. The SE/JE/Signal shall check his watch, if available with Guard's time, station time and control time, as the exact time of an accident is often an important clue in determining the cause of the accident. 2. Action at Site. If the Signal Supervisor is not the senior-most official present at the site of the accident he shall report to the senior-most official and render all possible assistance to him in taking action detailed in Paras 2.1 to 2.8 below. If however he is the senior-most official on the spot he shall himself initiate such action. 2.1. Check that the obstructed line including adjacent lines on a multiple line section is protected as per rules. 2.2. Arrange for medical aid to the injured taking the help of medical practitioners, if available. 2.3. After a rapid survey of the position, send brief particulars to the nearest SM to enable him to issue the all concerned message. 2.4. Record the statements of staff and take whatever steps may be necessary to record or preserve the evidence which subsequently may not be available. This shall be done by an officer or SSE/JE/Signal present at the site of the accident even if he is off duty. Evidence shall be collected and recorded with due care and attention and later submitted to the Enquiry committee. 2.5. Preserve all clues and record the character and relative position of markings to enable reconstruction of the scene of the accident. Where immediate repairs are necessary to pass trains, only such parts of the interlocking gear shall be disconnected as are necessary to carry out the repairs to the Track. 2.6. Scrutinise and initial jointly with the concerned officials noting time and date the Train Register Books or Train Message Books, Private Number Books, Caution Orders, S. & T./MR, S. & T./DN forms concerned and any other relevant records. Secure and seal immediately the records directly connected with the cause of the accident. 2.7. Devote special care and attention in the collection and recording of evidence as prescribed and in submitting the evidence with all details to the Enquiry Committee. Note: The object of recording all available data at site and presenting the evidence at the enquiry is to ascertain the cause of the accident with a view to prevent its recurrence and, where the cause is due to negligence, to fix responsibility. Chapter 3: Duties Of Signal Supervisors And Technical Staff Page 34 of 530  2.8. Report the position at site of the accident to the Control Office and to the Sr. DSTE by the quickest possible means. 3. Special action by SSE/JE/Signal - The SSE/JE(Signal) shall pay special attention to the following: 3.1.

Chipped length is the portion where tongue rail has worn out for a depth of more than 10mm over a continuous length of 10 mm. (b) Developed a knife edged tip — thickness of tip less than 2 mm over a length of more than 100mm anywhere up to a distance of 1000 mm from its toe. (c) Badly twisted, does not house properly and cause a gap of more than 5 mm at the toe. (d) Vertical wear which is measured at a point where tongue and stock rails are at the same level. Vertical wear allowed is 8mm for 60 kg. Lateral wear is 8 mm for 60 kg. (e) Burred stock rail to be replaced. (f) Tongue rails should bear evenly on all the slide chairs. (g) All sleepers should be packed properly. (h) When the tongue rail is in closed position, it must bear evenly against distance studs or blocks. (i) Wear on switches can be reduced by lubrication of the gauge face of the tongue rail. (j) On wooden sleeper layout assembly, the slide chairs should be fixed to the timbers by plate screws. Round spikes not to be used for this purpose. 4.2 Measurement And Reading – Track And Vehicle (i) Track Readings At Accident Site. Gauge should be checked at the following locations in case of points and crossings.  305 mm (1 foot) in advance of nose of tongue rail.  152 mm inside nose of tongue rail for straight and turn out.  At middle of tongue rail for straight & turnout.  At heel of tongue rail for straight & turnout. Note: Gauge should be correct at all locations except at toe. At toe, for PSC layouts up to 3 mm tight gauge is allowed. (ii) Gauge at Crossings  610 (2 feet) in advance of nose of crossing on straight & T/Out  152 mm behind the nose of crossing on straight & T/Out  76 mm behind the nose of crossing on straight & T/Out. The gauge should be correct. (iii) Check rail (Wing Rail) Clearance on Crossings:  BG 44 to 48 mm  MG 41 to 44 mm Ensure checkrail clearance should be between the values mentioned above. (iv) Measure vertical wear of stock and tongue rails. Maximum permissible vertical wear on wing rails or nose of crossings: 10 mm Chapter 3: Duties Of Signal Supervisors And Technical Staff Page 37 of 530  Rail Section BG MG S/Rail 60Kg 13 mm --- (wing rail also) 52 Kg 8 mm --- 90 R 5 mm 6 mm T/Rail 1 60 Kg. 8 mm --- 2 52 Kg/90R 5 mm --- (v) Measure Lateral Wear of stock and Tongue Rail S/Rail 8 mm/10 mm max for A, B/Other routes in straight line 6 mm/8 mm max for A, B/Other route in curve T/Rail 60Kg - 8 mm max ----- 52Kg/90R - 6 mm max ----- Measure both wears on T/rail at a point with 13 mm head width and at the point where T/Rail and S/Rail are at the same level (vi) Check for angular wear of Stock Rail (vii) Check for clipping of T/Rail within 100 mm (1 Metre ) from toe (viii)Check for knife-edge of T/Rail within 1 m from toe. If the thickness of the T/Rail in less than 2 mm continuous for 100 mm (10 Cms) anywhere within 1 meter from ATS then it is knife edged. (ix) Measure track readings (Gauge, Cross level, Versine etc) jointly. STN. STN. STN. STN. STN. STN. STN. STN. STN. STN. + 15 +3 +2 +1 '0' -1 -2 -3 - 15 - 30 POD POM DIRECTION OF 45 Mts. 45 Mts. TRAFFIC 90 Mts. Fig No : 4F2  Identify and mark Point of Drop (POD)/Point of Mount (POM) as Station ‘O’. In case both POD/POM are available then take whichever is first to come (moving in the direction of the train) as Station. ‘O’  Mark 15 Stations 3 m apart in rear of POM/POD up to 45 Metres. Station ahead are marked +1, +2 etc, and rear are marked –1, -2, etc. (Note: In case of any doubt of POM/POD, mark another 15 stations in rear from the suspected POD/POM at 3 Metres up to 90 Metres. i.e. total 30 stations in rear because clues for the cause of the accident are available mostly in rear portion.)  Take the reading at every sleeper up to 3 stations (i.e. up to 9 Mts.) on both sides of POD/POM.  Measure the gauge, cross-level and versine jointly  The versine difference between the standard value and the recorded value at every point shall not be more than + 4 mm.  The difference between any two recorded values shall not be more than + 3 mm Chapter 3: Duties Of Signal Supervisors And Technical Staff Page 38 of 530   If the versine difference is not within the limits of + 4 mm between std value and any recorded value and/or within + 3 mm between any two reading then the track curvature is defective. Note: A crossover point is a track in curvature, but without any super elevation. Hence all the parameters need to be maintained correctly. 4.3 Track Twist: It is an important parameter having crucial impact on safety. The rate of change of cross-levels is called ‘twist’. Cross-level means difference of level of rails. Cross- levels are measured on left rail as seen in the direction of train involved in derailment. LEFT RIGHT A B Fig No: 4F3 Track Twist = Algebraic difference of Cross Level at A & B in Distance between A & B Example: Cross level at ‘A’ = +5 mm (Left rail is higher than right rail by 5 mm) Cross level at ‘B’ = -7 mm (Left rail is lower than right rail by 7 mm) If the distance between A & B is 3 meters, Then Track Twist = (+5) – (-7) = 12/3 = 4 mm / Mts. 3 4.4 Permitted Cross Level Difference (Twist): For a new track, cross level difference permitted is 1 in 720. A vehicle with defective spring gear travelling on a track with twist can cause derailment. In cases of improper loading, the chances are further increased. 4.5 Draw a Sketch of the Accident Site and note (a) Make the exact position where engine & vehicles came to rest. (b) Prepare a diagram of the Engine and all the vehicles with reference to track indicating the position of derailed vehicles etc. (c) Exact position where loose components of vehicles and track are found. (d) Whether Engg. staff were on work (e) POM/POD, damage to sleepers, rails and other track fastenings. (f) Position of wheels in relation to displaced rails in normal alignment. (g) Condition of track at least ½ a mile in rear. (h) The condition of signals, points, L/Bars, Levers/Knobs and their relevant indications, SM slides, position of Block Instrument etc. (i) Whether any S & T Staff working (j) Check the records, register, PN books etc. Seize the order books, if required. (k) In case of shunting operation whether proper locking & clamping of points done or not. Chapter 3: Duties Of Signal Supervisors And Technical Staff Page 39 of 530  4.6 CARRIAGE AND WAGON Related Items: (a) Variation in wheel diameter within the wheels of same axle shall not be more than 0.5 mm for both goods and coaching stocks.  Difference of wheel diameter between wheels of same axle - within 0.5 mm.  Difference of wheel diameter between wheels of two adjacent axles of the same trolley: Goods: within 13 mm Coaching: within 5 mm.  Difference of wheel diameter between wheels of different trolleys of a bogie: Goods: within 25 mm Coaching: within 13 mm. (Note: Due to difference in wheel diameter, there will be angular motion of the wheels. Wheel with lesser diameter may have tendency to mount over rails and derail whereas wheel with higher diameter will cause increased wear and tear) (a) Sharp Flange  Flange of the wheel sometimes wears to form a knife edge which becomes unsafe when radius of the flange at the tip is less than 5mm.  A wheel with sharp flange has biting action particularly while negotiating curves.  Sharp flange may split open a slightly gaping point.  While travelling in facing direction it may even mount the tongue rail.  Rejection limit for flange tip radius is less than 5 mm for BG/MG (c ) Thin Flange  Flange becomes thin by wear and tear of the tyre and flange and is considered unsafe when it becomes less than 16 mm.  This increases clearance between wheel flange and rail, which in turn increases the derailment proneness.  Oscillations increase due to greater play between wheel set and track resulting in greater instability of the vehicles  Rejection limit is 16 mm BG/MG measured at 13 mm from the flange tip.  It also damages tongue rails due to more play. (d) Flat Tyre /Skidded wheel  It may occur due to continuous brake binding, skidding, brake block tilting and jamming against the tyre.  Flat tyres cause passenger discomfort and may become unsafe.  Flat tyre causes greater hammering action on the rail and rail fractures may take place. (e) Deep Flange  Deep Flange may hit track fittings like fishplate joints, lock bars, point and distance blocks.  A deep flange tends to ride on fishplate and distance or check blocks and damage the track, particularly if there is vertical wear on railhead.  Rejection limit in depth of flange greater than 35 mm (BG), 32 mm (MG) measured at 63.5 for BG and 57 mm for MG away from back of wheel. (f) False Flange/Hollow Tyre.  Excessively worn-out tyre on tread is a hollow tyre. Hollow tyres develop a false flange. The false flange formed may force open the switches when the vehicle runs in the trailing direction on points and crossing.  False flange can be dangerous at the wings of crossing as it may ride over the wing rail, lifting the wheels and creating conditions favourable to derailment.  If the hollowness is more then it results in difference in wheel diameter and the wheel may ride over the rails.
