New technology inputs to loco.
 

 Item

  Features

MCBG

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.

MEP

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.

VCD

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.

REMMLOT

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 there locos through GPS.

WDG4 locos

These are new generation, high horsepower locomotives which are being inducted into Indian railways. These have High HP and more fuel efficient.

CCB

New generation WDG4 locomotives are equipped with computerized controlled braking system.

 
Important facilities available
1. Under floor wheel lathe for wheel turning.
 

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.

2.Spectrography for analysis of lubricating oil.
 

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.  

3.DM water plant.
 

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.

4.

Water Load Box
 

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.

Future infrastructure development plans
1.In order to home the new generation, high horse power WDG4 Locos, Light schedule bay no.1 & 2 is being extended by 12 mtrs. 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;
 i)Simulator for  Computerised Controlled Braking  system.  
 ii)Test bench for Brake controllers.
 iii)Material storage and racking system.
5.Under sanction works Programme - 
 i)No. 5 pit line will be extended up to wheel lethe.
 ii)Compound wall will be extended.
