Metro

Medha has collaborated in over 240 new Metro EMU builds, and have involved in modernisation programs globally in regions such as the UK, USA, France, Italy, Brazil etc.

Metro’s are Electrical Multiple Unit’s (EMU) designed for shorter distance urban transit and for frequent stops and high capacity passenger movement. Medha EMU’s  operates at a maximum speed of 100 km/h. The EMU’s design, control and propulsion technology are state of the art with energy saving and safety features.
