The HOG system does not require any diesel oil consumption and as such will reduce air pollution and also noise pollution. In addition, it also provides uninterrupted illumination in the coaches.
In the first phase, all but two trains (totalling 10 trains) having total LHB coaches and running end-to-end with electric traction facility have been converted to HOG technology. In addition, one more train with LHB coaches (i.e., Rayalaseema Express) running partly in diesel section has also been converted into HOG within the electrified section.
