Examination Departmental wagon stock. • All the departmental wagon stock which run with goods train like camping, mobile training car, OHE wiring trains etc shall allotted a C&W depot for primary maintenance, nominated by a mechanical officer. • The depot allotted to be painted on the end wall. • The stock to be examined by mechanical supervisor at nominated C&W depot • The brake power certificate shall valid for a specified period from the date of issue. • All the departmental wagons, material trains, ballast trains, PQRS Trains etc shall be examined as per IRCAPart iii.

EXAMINATION Ø Detailed Joint circular shall be issued by a committee consisting of CME, COM of the zonal railway or their nominated officers. Ø Track machines also be subjected to examine for wheels, under gear and structural safety. Ø BPC of the above to be issued by mechanical supervisor at periodical interval as decided by concerned zonal railways.

Ø If the rolling stock cannot be despatched to the nominated depot for primary maintenance, the same must be offered to the nearest train examination station for certification. Ø Apart from the periodical examination by nominated supervisor, the in charge/custodian of the rolling stock shall be carry out the rolling stock before starting the operation. Ø In case he notice /suspects any abnormality in the rolling stock he should arrange examination by C&W supervisor immediately. Ø The station master shall not give permission to start the train /departmental stock unless the in charge of the train produce valid Brake power certificate issued by the mechanical supervisor.

Ø Material train should be expeditiously and economically worked. Ø The Assistant Engineer should arrange to form a train of maximum capacity consistent with the haulage capacity of the engine and tonnage approved for the section. Ø In consultation with the Operating Department, the running of goods trains should be suitably regulated so as to provide as long a working time for material train as possible.

REPORTING DIFFICENCY AND DAMAGES Ø The Guard of the material train should at once bring to the notice of the Train Examiner under advice to the Assistant Engineer, any deficiency or damage which may have escaped the attention of the train examining staff.

REPORTING DIFFICENCY AND DAMAGES Ø The Guard will also keep a record of all damages caused to the vehicles during the work and report to the Assistant Engineer the circumstances in which they occurred. In every case, the Assistant Engineer on receipt of such reports should arrange for the train-examining staff to attend to the damages and deficiencies expeditiously.

ENGINE CREW HOURS DUTY. Drivers, Assistant Drivers and on material train should be relieved according to their duty rosters. Ø Only in exceptional and emergent cases such as breaches on the line, may the engine crew be kept on duty, for long hours, in which case, a special certificate should be given to the Engine Crew by the Engineering Officialin-charge. Ø

OPERATION OF HOPPER Ø The hopper valves shall be operated according to the prescribed instructions under the direct supervision of the train guard or official-in-charge. Ø As far as possible one hopper may be unloaded at a time moving at walking speed.

OPERATION OF HOPPER Ø The official-in-charge should walk on the side and instruct the labour as to when to open or close the hopper valves. Ø The train should not be stopped, while ballast is being discharged ; labour should not be moved from the platform without first stopping the train.
