Full Form of DGV
What is DGV?
A Diesel Generator Van (DGV) is a specialized railway coach equipped with a diesel-powered generator set, designed to supply electrical power to passenger trains for lighting, air conditioning, fans, and other onboard amenities. In the Indian Railways network, DGVs are commonly attached at the rear of trains that lack an overhead electric power supply, such as those hauled by diesel locomotives or operating on non-electrified routes. They play a critical role in ensuring passenger comfort during long-distance journeys, especially in regions where electrification is incomplete. Indian Railways operates thousands of DGVs, often paired with LHB or ICF coaches, to provide hotel load. The use of DGVs has declined in modern trains with the adoption of Head-On Generation (HOG) and End-On Generation (EOG) systems, but they remain essential for heritage and shorter tourist routes. For competitive exams like RRB NTPC and railway recruitment, understanding the function and placement of DGVs is important for the science and engineering sections, as it reflects practical applications of power generation and distribution in transport.
