Diesel Loco Shed, Pune is a engine shed located in Pune, Maharashtra in India. It is located east of Pune Junction, falling under Pune Railway Division.[1] Of the three loco sheds in the Central Railway zone, this is the largest among them followed by Kurla and Kalyan.[2][3]

History and developments[edit]

An old WDG-3A loco from Pune Loco Shed

It was on 13 August 1981, the then railway minister Kamalapati Tripathi inaugurated the loco shed.It was planned under WP 1978 – 79 to home 60 locos. The shed was further extended to home 100 locos under WP 1981 – 82. Now it holds around 135 locomotives of which 63 locos are operational with mail express links, (As per 2011)[4] but now it holds almost 200 locomotives.(As per 2015)

Major and minor schedules of Diesel Locomotives are carried out in the shed. The shed is ISO 9001:2000, ISO 14001:2004 and OHSAS 18001:2007 certified. The shed is divided into Light Schedule Repair Section, Heavy Schedule Repair Section, Heavy Repair (Mechanical), Heavy Repair (Electrical), Bogie Section, Machine Shop and Training Centre. The shed is located near Ghorpuri railway station and entrance of the shed is between a railway crossing gate.[4][5]

The total area covered by the Shed is 59, 825 Sq. m and the covered area is 11, 386 Sq. m. The total berthing capacity of the Shed is 22 Locos.


New technology inputs to loco[6][7]

S.No Item Features
(Microprocessor based governors)
MCBG or "Microprocessor based governors" are fast replacing hydro-mechanical governors used in earlier days. These governors are more efficient and effective in controlling fuel consumption as well as in utilizing power of diesel engine.
(Mechanical, Electrical, and Plumbing Systems)
Existing excitation control system is being replaced by microprocessor based system which is having fault logging, data recording facility and interactive screen in driver cab. Hence, it is helpful in maintenance and troubleshooting and thereby improving online availability and reliability of Locomotive.
(Vigilance Control Device)
VCDs are provided on locomotives, so as to keep loco pilots vigilant all the time. If no any operation is carried out within 60 seconds then VCD will give indication for 17 seconds, still no response for another 17 seconds audio visual indication will come. After 94 seconds penalty brake will be applied and train will be stopped automatically.
(Remote Monitoring and Management of Locomotives and Trains)
Loco remote monitoring system is being provided on locos for monitoring their critical parameters in real time. This is helpful in doing predictive maintenance as well as shed can have the location of their locos through GPS.
5 WDG4 locos These are new generation, high horsepower locomotives which are being inducted into Indian railways. These have High HP and more fuel efficient. These are used for functioning with Goods trains.
6 WDP4 locos These are new generation, high horsepower locomotives which are being inducted into Indian railways. These have High HP and more fuel efficient. These are used for functioning for Passenger trains. These have a capacity to function with 26 bogiees.
(Computerized Controlled Braking System)
New generation WDG4 locomotives are equipped with computerized controlled braking system.


Important facilities available[6]

Under floor wheel lathe for wheel turning[edit]

This is utilized for maintaining wheel profile, without removing wheel sets from locomotives. This saves a lot of time and effort which otherwise would have gone into it.

Spectrography for analysis of lubricating oil[edit]

This is helpful in doing predictive maintenance. By this machine, lube oil of locomotives is analysed for various metallic traces which would have come into lube oil due to wear and tear. Any metallic trace showing unusual concentration indicates to the distressed condition of related component.

DM water plant[edit]

The cooling water used in locos should have pH value within a specified range. This pH range is maintained with the help of DM water plant. The process used is ion exchange regeneration process.

Water Load Box[edit]

This facility is utilized to test the horse power of locomotive by simulating online full load condition. The various parameters of locomotive are tested as per their standard values and any deviations are rectified.


The shed is headed by Sr. DME (Diesel), has about 750 employees in different ranks in the day-to-day operations of the shed, which include periodical overhaul, maintenance and repair works. The locos of this shed were thoroughly traverses over entire western India for passenger and freight services. The operations of the shed is divided into various sections, for proper functioning.[6]

Future infrastructure development plans[edit]

  1. In order to home the new generation, high horse power WDG4 Locos, Light schedule bay no. 1 & 2 is being extended by 12 metres towards Miraj end which will increase the berthing capacity by 02 locomotives.
  2. No. 1 & 2 service line pit depth will be increased and steel columns will be provided in place of RCC columns at distance of one meter which will increase he accessibility of under gearing.
  3. Roof ventilators will be provided for air ventilation.
  4. In Works Programme 2012-13 the following machinery & plants have been proposed for EMD locomotives;
  • Simulator for Computerised Controlled Braking system.
  • Test bench for Brake controllers.
  • Material storage and racking system
  1. Under sanction works Programme -
  • No. 5 pit line will be extended up to wheel lethe.
  • Compound wall will be extended.[6]

Rolling stock[edit]

The shed homes about 200 diesel locomotives of varied types, which are its primary rolling stock of the shed.[6]
