Introduces Head On Generation system to reduce power consumption and operational costs

The South Central Railway (SCR) announced the introduction of a new technology – Head On Generation (HOG) system – in Telangana Express where power from the engine would be supplied to the entire train for lighting and air-conditioning from Wednesday onwards.

Senior officials said the trains like these have two power cars known as End On Generators (EOG) on either end to provide electricity to all the coaches. These power cars produce electricity by the diesel generators with each using 40 litres of fuel per hour for a non-AC coach and 65-70 litres of diesel per hour per coach in case of an AC coach.

The new HOG technology obviates the need for using diesel as power is tapped from the overhead electric traction lines through a pantograph to the train engine and the same is distributed to the trailing coaches. Earlier, the power supply from the overhead electric traction was being used to only run the engine and haul the coaches.

“The new system does not require any diesel and hence, will reduce air and noise pollution, besides providing uninterrupted illumination in all the coaches. On an average, it will reduce carbon emission by 700 metric tonnes per year per train,” they explained.

If the average expenditure incurred on fuel consumption per trip per train of Telangana Express was around ₹2 lakh, the new method would reduce the electrical energy consumption cost per trip per train to around ₹78,000 with the estimated savings for each trip being about ₹1.22 lakh, which comes to about ₹1.35 crore annually.

General Manager Gajanan Mallya said from now on, the Telangana Express trains would run on HOG systems only. It would be the third such train to have this technology in the zone with the other two trains being Visakhapatnam- Tirupati- Visakhapatnam Express and Tirupati - Jammu Tawi -Tirupati Humsafar Express.

Mr. Mallya advised his officers to extend the same to some more trains to adopt environment-friendly initiatives to reduce carbon footprint.
