The Research Designs and Standards Organisation (RDSO) of Indian Railways has come up with a new technology to cater to the power requirements of the fully air-conditioned super fast trains, as well as other passenger trains, which will not only save fuel but also cut down on the cost of running the trains.
The green technology, called Head On Generation (HOG), is already being used in the New Delhi-Kalka Shatabdi Express for over a month now.
“In 2007, the railway board approved of RDSO’s proposal for this technology and after several successful trials, the Railway board approved the introduction of the HOG in New Delhi-Kalka Shatabdi from February 21, this year,” said AK Mathur, Executive Director Administration, RDSO.
The technology functions by harnessing the electricity from over-head wires of the electrical locomotive system —which is basically used for the power requirement of the engine — to cater to what the Railways calls the ‘hotel load’ of the train.
