Diesel multiple unit. Diesel-powered passenger vehicles that replaced steam engines on non-express (suburban, rural, commuter) railway lines.
Diesel multiple unit or DMU: A set of diesel-powered self-propelling passenger rail vehicles able to operate in multiple with other such sets. Such units, especially those consisting of a single vehicle, are sometimes termed railcars.
