Multiple unit cars (Qbfmkm)

Definition
Two or more units or connected pairs of railcars equipped so that all cars in the train may be operated from any car that has an operator's station. Also, railcars that are propelled by some form of motor located on the car itself and can often operate in multiple units; common types are electric, which are equipped with electric motors and receive current either from a third rail or from a trolley wire, and those that are propelled by internal combustion engines, which may have either electric or fluid drive. Also, the term multiple unit or MU is used to describe a self-propelling train unit capable of coupling with other units of the same or similar type and still being controlled from one cab. The term is commonly used to denote passenger trainsets that consist of more than one carriage, but single self-propelling carriages, or railcars, can be referred to as multiple units if capable of operating with other units.
