Organization:
The loco shed is at present headed by the rank of JAG grade Senior Divisional Electrical Engineer assisted by one Divisional Engineer, one Assistant Divisional Engineer along with Senior Material Manager who is responsible for managing the procurement, stocking and distributing of stores to various sections.
The loco maintenance wing is divided into main sections headed by a Senior Section Engineer and assisted by junior supervisory staff to monitor and improve various maintenance schedules and modification works carried out in the section. A locomotive nominated for maintenance is first received by the PPO section and dispatched out through the same section after completion of the maintenance.
The role played by the other sections namely, Traction Motor, Bogie, Auxiliary Machines, Electronics, SPM and Relay, TFP & GR, Pneumatic, Technical, Tool Room, Machine Shop, General and Store section is vital in completing the process. In a nutshell, it is a comprehensive team effort that keeps the wheels on the move.

INNOVATION/ GOOD WORK DONE
1.To avoid dropping of slack adjuster assembly (bottom) in case of breakage of its Split cotter pin in WAP7 locos, ELS/LGD proposed provision of hexagonal head bolt with plain washer and castle nut in place of slack adjuster pin with split cotter pin. The item was discussed during 37th MSG meeting and accepted by Railway Board. RDSO issued Modification No. MS 441 for this arrangement to all Zonal Railways.
2.The falling of brake hanger was observed which are supported by single headless pin in WAP7 locos. To prevent the falling of brake hanger in case of brake hanger pin coming out, E clamps have been developed and provided by ELS/LGD for brake hangers5,6,19&20 which acts as stopper for the brake hanger lever pin. RDSO issued Standard Maintenance Instruction no. SMI 282 on this arrangement to all Zonal Railways.
3.ELS/LGD proposed to remove anti spin valve and associated double check valve in brake system of three phase locomotives since they are not in service. This was proposed by SCR in 37th MSG meeting and accepted by Railway Board.RDSO issued Modification no. MS 447 to all Zonal Railways.
4.ELS/LGD proposed to carryout insitu Magnetic particle testing on TM motor support of 3 phase locos during schedules to detect the cracks.Accordingly RDSO issued Maintenance instruction No.269 Rev.1’ dt:16-3-16 to all Zonal Railways.
5.ELS/LGD has highlighted the problem of non availability of C clearance of MSU which is leading to MSU failures in 3phase locos. Accordingly RDSO issued modification no.456 Rev'0' dt:9.1.17 for Modification in drawing of supporting ring to achieve adequate 'C' Clearance in MSU assembly of 6FRA-6068 TM in WAG9/WAP7 class of locomotives.
6.ELS/LGD proposed to review MOH schedule periodicity of WAG9 locomotives from 18 months to 24 months.During decisions on recommendations of 61stESC Railway Board accepted the proposal and RDSO vide letter no. RDSO Lr No. EL/3.6.1/1, Dt.19.10.16 had issued Revised MOH (TOH) schedule for WAG9 for 24 months.
REDUCING EXPENDITURE:
INDIGENOUSLY DEVELOPED TRACTION CONVERTER COOLANT PUMP:
Converter coolant pumps which are received in M/s BHEL make IGBT Traction Converter locos are of magnetic coupling type and having high failure rate. The cost of the pump is high (Rs.12,98,903/-approx) and the maintenance time is also high. ELS/LGD has explored indigenous market and developed a converter coolant pump through M/s Flowwell at the cost of Rs.1,10,548/- and achieved effective cost saving of Rs.11,88,355/- percoolant pump( RS.23,76,710/- per loco approx). This was accepted by Railway Board & RDSO in 38thMSG meeting.
Reducing energy consumption:
- Three phase locomotives are equipped with regenerative braking. These locomotives have contributed saving of Rs. 15.9 crores during 2009-10, Rs. 20.3 crores in 2010-11 & Rs. 11.3 crores during 2011-12 upto August (Rs. 4.5 /unit) through regeneration of energy.
