Push–pull train

Push–pull is a configuration for locomotive-hauled trains, usually having a locomotive on one end and a control car on another, connected via some form of remote control, such as multiple-unit train control.

This formation meant that the locomotive would not have to run-around at the end of a journey before returning.

The trains were also historically knows as "motor trains" or "railmotors", but the term "railmotor" is now used to refer to trains where the locomotive was integrated into a coach. In the UK and some other parts of Europe, the control car is referred to as a driving trailer (or driving van trailer/DVT where there is no passenger accommodation); in the US and Canada, they are called cab cars and in Australia, they are called driving trailers.
