Indian Railways to adopt HOG system to save Power cost

This new rail project means lakhs of additional seats in trains; saves Rs 1,400 crore!

NEW DELHI: Noise pollution and massive fumes from trains’ power generator car will soon be a thing of the past. A clean technology—Head on Generation (HOG)—is being adopted by the Indian Railways, power supply is tapped from overhead power lines and distributed to train coaches.  The HOG system makes use of overhead electric supply to supply power to the coaches. This eliminates the need for two power cars to be attached to LHB rakes on the network, hence helping save crores of rupees in diesel consumption.

“The power generator cars which used to make huge noise and emit fumes will no more be there. In place of two such generator cars there will be one standby silent generator car to be used for emergency,” the railway ministry said.

The new technology is expected transform the way air conditioners (ACs) run and power is supplied in the railway coaches, the railway ministry said on Tuesday, adding that this will result into a foreign exchange saving of about 1,400 crore per year as it will reduce dependence on diesel. Currently, there are one or two power cars at the end of every train in every Linke Hofmann Busch (LHB) rake, where the electricity to be supplied to coaches is produced in a diesel generator.

The new technology HOG will be available at 6 per unit as compared to end EOG system, in which cost of power is 22 per unit.

“In place of the other car, there will be…LHB second luggage, guard and divyaang compartment,” the ministry said. As a result, beginning October, more than four lakh additional berths will be available to passengers everyday.

Rajesh Agarwal, member, rolling stock at the Railways Board told reporters that there is a plan to convert all LHB trains to HOG technology within the end of the current financial year. As of now, 342 trains have already started using the new technology.

Apart from the announcement pertaining to new clean technology, on Thursday, the national carrier announced slew of incentives, such as deferring its busy season surcharge of 15% during October 1 to June 30 on freight. The automobile sector, which is looking at cutting costs, amid falling vehicle sales, had requested the railways for more rakes. Towards this, national transporter will hike the number of rakes for the automobile sector to ramp up freight loading.

According to Agarwal, the step is a transformational one. “PM Narendra Modi and Railway Minister Piyush Goyal are clear that we have to focus on transformational steps, instead of incremental ones. This move from EOG to HOG for LHB coaches will be a win-win for all – we will save a huge amount of money, it is very eco-friendly, it is in line with global standards and passengers benefit in the form of increased number of seats and the reduced noise pollution,” Agarwal told
