Inter-city and Metros
EMU’s are self-propelled train sets that use electricity from a power source either overhead or third rail. They consist of multiple carriages, multiple of them with its own traction motors and control equipment. EMU’s mainly function as metro or suburban trains. Medha has collaborated in over 200 new EMU builds.
