===Diesel–mechanical {{Anchor|DMMU}}=== In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a [[Transmission (mechanics)|gearbox]] and driveshaft directly to the wheels of the train, like a [[automobile|car]]. The transmissions can be shifted manually by the driver, as in the great majority of first-generation [[British Rail]] DMUs, but in most applications, gears are changed automatically.
