Indian Railways saves crores, by becoming more environmentally-friendly. Premium passenger trains of Indian Railways with AC coaches which generally run on the End-on-Generation (EOG) system are now being converted to Head On Generation (HOG) converters.
The HOG system is an improvised converter which utilizes power from overhead catenary in order to feed auxiliaries in the coaches hauled by electric locomotives. It saves up to 1 million litres of diesel per train per annum. Over the years, the locomotives that have been manufactured by Chittaranjan Locomotives Works (CLW) are HOG compliant.
Moreover, from April 2018 onwards, the pace HOG conversion works for Linke Hofmann Busch (LHB) coaches have been increased to harness the benefits of this high-end technology. Between the period April 2018 and 5th November 2019, a total of 436 trains (cumulatively more than 500 trains) have been turned into the energy-efficient and eco-friendly technology.
The HOG systems not only reduce noise but also significantly cut down on C02 emissions.
As of now more than 550 electric locomotives have been provided with HOG converter technology and are yielding benefits of savings on fuel bills to Indian Railways, besides being a noiseless and emission less solution to the EOG variant, said a statement by the Railways Ministry. With major advantages of the HOG system including reduced noise, a significant cut in C02 emissions, reduction in diesel consumption and overall economical, the railway ministry is focused on producing more of HOG compliant locomotives in order to curb operational costs while being environmentally friendly.
According to the Railway Ministry, all passenger electric locomotives that are being produced in Indian Railways Production Units Namely CLW, Diesel Loco Modernization Works (DMW) and Diesel Locomotives Works (DLW) as well as all passenger coaches that are manufactured in integral Coach Factory (ICF), Modern Coach Factory (MCF) and Rail Coach Factory (RCF) are now all HOG compliant.
