The word originates from the Latin "loco" "from a place", ablative of "locus", "place" + Medieval Latin "motivus", "causing motion", and is a shortened form of the term "locomotive engine", first used in the early 19th century to distinguish between mobile and stationary steam engines. - The British Railways Board (BRB) was a nationalised industry in the United Kingdom that operated from 1963 to 2001.

Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in 1962: the British Railways Board. - A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. They may also be referred to as a railcar or railmotor, depending on country.

Often these are passenger trainsets consisting of more than one carriage. Single self-propelling carriages (also called railcars, rail motor coaches or railbuses) are multiple units if capable of operating with other units. - Cravens Railway Carriage and Wagon Company Limited was a railway rolling stock builder in the Darnall district of Sheffield, England.
