East Coast Railway saves Rs 118.29 crores by using HOG system (Head on Generation technology) in LHB Coaches trains

55 trains (65 rakes) converted into HOG under East Coast Railway Zone resulting in saving of approximate Rs. 118.29 crores in between April 2022 to November 2022.

In line with Nationally Determined Contribution (NDC) to be communicated to the United Nations Framework Convention o­n Climate Change (UNFCCC) and in tune with the vision of our Prime Minister, Shri Narendra Modi India now stands committed to reduce Emissions Intensity of its GDP by 45 percent by 2030 and achieve about 50 percent cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030.

With the Prime Minister’s vision and under the guidance of Railway Minister, Shri Ashwin Vaishnaw, Indian Railway has planned to gradually reduce its carbon footprint and become Net Zero Carbon Emitter by 2030. Indian Railways is taking several measures to achieve the Net Zero Carbon Emitter target. Adoption of HOG system (Head o­n Generation technology) in LHB coaches in trains is o­ne such step towards fulfilment of this vision.

To fulfil this vision and as per the direction of Hon’ble Railway Minister, Shri Ashwin Vaishnaw,  General Manager, East Coast Railway Shri Roop Narayan Soonkar has advised the officials to take up the task to full fill the target.

As per this target, East Coast Railways has till date converted 55 trains (65 rakes) into HOG system (Head o­n Generation technology) and thereby saving of Rs. 118.29 Crores in Diesel fuel consumption due to running of HOG rake between April 2022 to November 2022.

In the new technology called - Head o­n Generation technology, the power is drawn from the Overhead Electric supply and the power generator cars provide noise free and pollution free environment for passengers at station. This technology uses o­nly o­ne standby silent generator car for emergency. Cost of electricity generation from DG set and in self generating coaches is very high in normal LHB trains resulting in increase in diesel consumption and substantial operating expenditure. The cost of power in normal LHB trains is over Rs. 36 per unit and in HOG system trains the cost comes down to Rs. 6 Per unit.

Brief about Head o­n Generation system:

Head o­n Generation system is electrical power supply system where electrical power for catering hotel load of train, which includes Train Lighting, Air conditioning, Lighting, fannage and other passenger interface requirement working o­n electrical power supply. The power in this system is received from locomotive. With introduction of this system heavy underslung power generating equipment gets eliminated. Further it also reduces use of Diesel sets employed in power cars in End o­n Generation system.
