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.
Related to amenities:
Dry sweeping, Cleaning, Swabbing, Watering, Pipe fitting
work, Trimming work, Carpentry work, Padlocking, Painting.
