EXAMINATION OF TRAINS
Ref: IRCA Rule Book Part – IV (Ch. 3)
Rolling In Examination: There are certain types of defects in rolling stock which can only be detected during the motion of train. To detect such type of defects, rolling in examination is adopted. This examination is carried out on all pass through trains and terminating trains. To carry out Rolling in examination, C & W staff and supervisor will take position on both sides of platform / line in which train is being received.
During examination following defects are detected:
Unusual sound due to flat faces on tyre of wheel in any vehicle of train.
Whistling sound from bearing, if unattended that can lead to hot box.
Hanging part or loose fitting on the vehicle.
Any Spring broken. Brake binding on any vehicle. Any component of spring suspension like bracket loose/broken etc.
Any abnormal behavior of vehicle during run.
Rolling Out Examination:
The procedure of conducting Rolling out examination is similar to rolling in examination. Supervisor and staff will take position for conducting examination ahead of engine and ensure that the brakes of all vehicles are in released condition and any other defect that can be noticed like in Rolling in examination and could have leftover during the previous examination and can hamper the safety of the train.
Sr.DME/ DME in charge shall nominate the location for carrying out Rolling in/Rolling out examination after personal inspection of site.
While nominating the site following should be kept in view:
Site shall provide unobstructed view of under gear from both sides.
Speed of the train shall not be more than 30 Kmph. The track should not have any rail joints at the location, It should cover the entire length of train.
Should have adequate space for arrangement of shelter for staff.
It should be ensure that proper lighting arrangement is provided on both the sides of the track at nominated spots for examination of under gear parts during night. Focusing of lights shall be done by keeping a coach on the line and adjusting the angle of light to illuminate under gear and bogie.
Examination of originating trains:All trains must be examined by the mechanical train examining staff before dispatch to ensure that all coaches in the train are fit to run, without rejectable defects (for rejectable defects, please refer to IRCA Conference Rules, Part IV). Station Master (SM) shall handover part B & C of check memo (T431) to Senior Section Engineer (C&W) after placement of the formation in pit line for Examination, cleaning and watering. After carrying out all necessary examination and work, SSE (C&W) shall communicate fitness of the train to Station Master by giving part C of T431 duly getting acknowledgement in part B. The Station Master shall not dispatch the train unless the fitness certificate is received from SSE (C&W).
The level of the air pressure/vacuum on the train engine and the brake van gauges as well as the percentage of operative cylinders should be recorded on Brake Power Certificate and signed by Junior Engineer/C&W, Driver and the Guard of the train. Trains which have been attended on pit line should have 100% brake power and no train shall be allowed with an inoperative/defective Brake cylinder on any coach after pit attention. Trains which are attended on platform or where secondary examination has been dispensed with or en-route should have minimum 90% brake power.
En route/Terminating Examination of Passenger Trains:
Rolling in examination of the train has to be conducted for the terminating trains. After train comes to halt, it should be ensured that the train is protected from both the sides (with the stop board/red flag during day time and red lamp during night time) before commencing the examination of the train. It should be ensured that a suitable indication board is placed at conspicuous location visible to the driver indicating that C&W staff is at work. Temperature of the axle boxes should be checked & recorded preferably with the help of the Non contact infrared thermometer. Brakes of the coaches to be released manually and ensure complete release by physically moving the brake beam. Other under gear parts should be examined visually to ensure that the train is safe to run further. Repairs if required should be carried out on pass through trains by taking shortest required time to avoid detention to train to the extent possible. Lavatories of the coaches should be properly cleaned using High pressure water jet machine provided at nominated stations during halt of the train. Any complaint from passengers should be attended promptly to the satisfaction of the passenger. After attending to any required repairs only stop board/red flag should be removed. C&W control should be informed about any out of course work done. C&W control shall repeat the out of course work done to the Primary Maintenance (PM) depot after corrective action. At the train examination stations where locomotives are changed on through trains, the level of air pressure/vacuum created on the locomotive and brake van gauges should be recorded on the BPC. The inoperative/blanked cylinders, if any, should also be written in the certificate for their information. This certification should be an endorsement on the 58 original brake power certificate; no fresh brake power certificate needs to be issued.
Pit Examination of Passenger Trains:
Related to safety:
Protect the Examination line. Thorough examination and repair of under frame, Bogie, Brake gear, Draw & buffing gear. Test and repair of Vacuum / Air brake system for Brake power including test/repair of Passenger alarm system. Lubricate all moving and rubbing parts. Give preventive maintenance schedule attention for the coaches except IOH.
