Delhi Division of Northern Railway cuts energy bill by 80% in 39 trains running on ‘Head on Generation’ system

Delhi Division of Northern Railway has achieved another unprecedented feat by converting and successfully running 39 pairs of Premium and Express trains on the “Head On Generation” (HOG) system. At present 11 pairs of Shatabdi, 08 of Rajdhani, 02 of Duronto, 02 of Humsafar and 16 of Express trains are running on this HOG system in Delhi Division.

Delhi Division of Northern Railway in its effort to cut down on its energy bills as well as strengthening environment conservation has introduced the head on Generation (HOG) technology in 39 trains having 51 rakes. The power supply tapped from power lines through pantograph to the train engine is used to run the engine and haul the coaches. In this new system power supply tapped from overhead to the train engine will be distributed to the trailing coaches for power needs. The HOG technology has been introduced in all the trains fitted with LHB coaches and hauled by electric traction. This technology caters to the power of the coaches such as coach lighting, air conditioning, etc. is alternate of earlier technology having two power cars in the trains known as End on Generation (EOG).

S.C. Jain, Divisional Railway Manager, Delhi said that the HOG system does not require any diesel oil consumption and as such will reduce air pollution and also noise pollution and it also provides uninterrupted illumination in the coaches. He further said that this is expected to save around ₹ 65 Crores per annum on diesel consumption of generator cars with the introduction of HOG technology.
