Indian Railways on GO GREEN mission: Induction of HOG systems, Electric locos gain momentum Southern Railway on fast track to becoming energy-efficient and eco-friendly


Indian Railways (IR) is working in mission mode to become the largest Green Railways in the world and is moving towards becoming a “net zero carbon emitter” before 2030.The following measures showcase how energy conservation measure are adopted in many facets of working in IR and Southern Railway:

Head o­n Generation (HOG): IR is introduced Head o­n Generation (HOG) system, whereby electrical power is fed to the coaches, for lighting and fans, directly from the Over Head Equipment (OHE) through the Locomotive. This eliminates the need for separate power car coaches and improves efficiency. 1,280 trains have been equipped with the HOG system in Indian Railways.  This will facilitate reduction in Carbon footprint by 31,88,929 Ton per annum and saving in fuel costs to the tune of Rs 2,300 crore due to elimination of power cars.

In Southern Railway, 27 pairs of trains were run with HOG complaint rakes during the year 2020-21. A total of 51 pairs of trains are running now with HOG locos which is yielding Southern Railway an annual savings of Rs.100 crores.

Reducing Pollution by Shifting from Diesel Locos to Electric Locos

With increasing electrification, Indian Railways has stepped up the production of electric locomotives significantly in the last few years.

Reduced use of diesel locomotives for train operation has resulted in increased share of electric Gross Ton Km (GTKM) (around 77%) as compared to 65.4% during 2013-14 in haulage of freight trains and huge savings in diesel consumption.

In Southern Railway during the year 2020-21, 27 pairs of trains were taken over from other railway in electric traction which has resulted in releasing 22 diesel locos. This has reduced the transit time required for loco change from electric to diesel traction and vice versa.

New and Better Locos with Higher Energy efficiency

Indian Railways has awarded a contract for supply of 800 electric locomotives with 12,000 HP Insulated Gate Bipolar transistor based three phase propulsion technology. These locomotives are energy efficient and have digital tracking features. 106 of these have been inducted o­n IR to haul heavier freight trains at higher speeds. At full load, its efficiency is 87%. It has been decided to produce o­nly 3 phase propulsion fitted electric locomotives in all three production units of Indian Railways.
