(b) and (c) Yes, Sir.    Indian Railways (IR) is committed to take new steps for energy conservation and to increase energy efficiency. Some of the measures taken are as follows:

- i) Use of energy efficient 3-Phase technology with regenerative features for electric locomotives, Mainline Electrical Multiple  Units  (MEMUs),  Electrical  Multiple  Units  (EMUs),  train  sets  for better energy efficiency.
2. ii) Introduction of Head On Generation (HOG) system in trains

Contd...2/-

to reduce diesel fuel consumption in power cars. 350 electric locomotives are equipped with hotel load converters.

iii) Provision  of  energy  efficient  Light  Emitting  Diode  (LED) lighting  in  all  Railway  installations  including  Railway  stations,  service buildings,  Residential  quarters  &  coaches  for  reduction  in  electricity consumption.

- iv) Regular  energy  audits  at  consumption  points  -  Energy Efficiency studies of six (6) Production Units (PUs) and four (4) Workshops were conducted and upto 15% energy efficiency improvement achieved.  This included activities like identification of significant energy saving opportunities, one day training program, identification of potential technology  suppliers  who  can  offer  energy  saving  technologies  to  the units etc.

v) Emphasis on use of 5 Star rated electrical equipments.

- vi) Regular training of Loco pilots for use of coasting, regenerative braking features and switching off blowers of electriclocos  in  case  yard  detention  is  more  than  50  minutes.  Similarly,  diesel locos are also shut down, if expected detention is more than 30 minutes (GHG)

and thereby resulting in reduction of Green House Gases emissions.

vii) Trailing locomotive of multi units (MU) hauling empty freight trains are switched off to save energy.

viii) Energy  consumption  on  electric  locomotives  is  regularly monitored  through  microprocessor  based  energy  meters  provided  in  all the  electric  locomotives  and  benchmarking  is  done  based  on  average energy consumption.

- ix) Monitoring the fuel consumption with respect to trip ration of diesel locomotive drivers.

- x) Auxiliary Power Unit (APU) has been provided in 986 diesel locomotives to reduce fuel consumption when locomotive is idle.
2. xi) Monitoring  of  idling  of  diesel  locomotives  is  being  done through remote monitoring and management of Locomotives and trains (called  as  REMMLOT).    2606  locomotives  at  present  are  equipped  with REMMLOT.

xii) Use of 5% bio-diesel in traction fuel- Blending of bio-diesel with HSD, to the extent of 5%, to save HSD.

xiii) 20% Compressed Natural Gas (CNG) substitution in DEMUs -CNG usage emits less GHG than liquid fuels. Indian Railways have the distinction  of  being  the  only  railway  in  the  world  to  be  using  CNG  run power cars for passenger transportation.  IR has also started conversion of  DEMU  Driving  Power  Car  (DPC)  into  dual  fuel  mode  DEMU/DPC  with CNG. 25 numbers of DPCs have been converted and are under operation.
