Career: Dmu

DMU stands for Diesel Multiple Unit, which is a type of train powered by on-board diesel engines, rather than a separate locomotive. DMUs are commonly used for passenger services on railway lines that are not electrified. They offer operational flexibility, as each carriage can have its own engine, allowing for efficient acceleration and deceleration. DMUs are widely used in regional and suburban rail networks around the world.
