16 Point Action Plan for Maintenence of AC COACHES

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 1.CESEs of the Railways to interact with their counterparts in other Railways to advise the unusual occurrences and obtain feed back. 2.All the AC coaches to be pre-cooled before placement of rakes on platform. This is the time when passengers require maximum and immediate comfort level. Pre- cooling cum emergency leads should be provided in all SG AC coaches (1 in each coach) and power cars (2 in each power car).

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 3No train to leave the Primary Depot with EFTs or equipments in isolated condition. 4Defects in the coaches to be noticed immediately after arrival of train and remedial action taken accordingly. Escorting staff should report at secondary maintenance depot and advise the status of coach and should sign the register with Depot and Depot staff to sign the Log Book with Escorting Staff.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 5All AC coaches from Primary depot should go with both Alternators working. If an Alternator cannot be replaced/repaired at the secondary maintenance depot, decision to send coach with one Alternator to be taken at officer's level. Second Alternator to be fully functional with full generation and the coach/ rake to be properly pre-cooled. 6AC coaches should go from Primary Depot with 6+6 belts on the Alternators and minimum 5+5 from Secondary Depot. Adequate facilities to be built up for changing the belt on rake itself.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 7The knowledge of all the ACCIs & ACCAs should be checked regularly regarding operation of the AC coach equipment as well as handling of the situation in case of failure of the equipment. ACCIs/ACCAs MUST maintain the log book and enter all the unusual occurrences. Training of AC staff of one week duration to be standardised by the Railways. 8Drive system for generation testing and Regulator setting to be introduced for alternators at all Primary Depots.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 9Unit Exchange Spares (UES) should be available in all depots. Each depot should have authorised holding of UES. Register should be available for each major UES at all the depots. 10 All the major depots should carry out failure analysis of major equipments and the information should be sent to RDSO periodically.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 11 The power supply system for pre-cooling to be augmented in view the increasing number of AC coaches in the depots. Railways to examine and take corrective action. 12 Railways to revise their EACs (Estimated Annual Consumption) of the material because of increasing AC Coach holding.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 13 Cleating of alternator field and phase wires to be properly checked at primary depot. 14 Full load and no load voltage of each cell of SMF batteries to be recorded (weeded out weak cell) every month for subsequent 3 months and if there is no abnormal variation in voltage, it should thereafter be recorded once in 3 months.

16 POINT ACTION PLAN ON MAINTENANCE OF AC COACHES 15 Working of thermostat should be monitored and recorded in log book. If thermostat is not found in working condition, the same should be attended/replaced by primary depot. 16 Working of WRA should be checked on arrival of train at primary/secondary depot and its working should be ensured before placement of rake at the platform.
