South Central Railways Introduces the HOG system in Telangana Express

The Head On Generation system, new technology was introduced in Telangana Express. It is commissioned on August 07, 2019 to meet the energy needs of coaches, such as lighting and air conditioning.

Previously, there were two powerful cars known as end generators (EOG) at both ends of Telangana Express for lighting and air conditioning coaches. These motor cars produce electricity using a diesel generator to power the buses. Each power car required 40 liters of diesel per hour by an unconventional coach and about 65 to 70 liters of diesel per hour and by an automatic trainer.

To reduce diesel consumption and carbon footprint, a state-of-the-art Head on Generation (HOG) system has been introduced in Telangana Express. Until now, the supply of power lines by the pantograph to the engine of the train is only used to run the engine and transport the coaches. Now, in this new system, the power supply connecting the overhead to the engine of the train will be distributed to towed cars.

This new system requires no diesel consumption and will reduce both air pollution and noise pollution. In addition, it also provides uninterrupted lighting in coaches. On average, it will reduce carbon emissions by 700 tonnes per year per train in regular practice for a train equipped with two engines equipped with diesel alternators. Average fuel consumption per trip and per train in Telangana Express is Rs. 2,000,000. While the cost of electrical energy consumption per way and train in the new system is around. 78,000 / -. The savings estimated for each trip from Telangana Express are about 1.22 lakh and the estimated total savings per year are about 4,000 rupees. 1.35 crore.

All existing Telangana Express trains will now be operated on the Head On Generation system. Two other trains, namely No. 22707/22708 Visakhapatnam - Tirupati - Visakhapatnam Express and No. 22705/22706 Tirupati - Jammu Tawi - Tirupati Humsafar Express, also use South Central Railway's new Head on Generation transmission system technology...

Shri Gajanan Mallya, General Manager of South Central Railway, commended the efforts of SCR staff and officials for this achievement.
