Autotrain

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

A driving cab in the rearmost coach (known as an autocoach or auto trailer) has controls to allow the driver to operate the regulator, brake and whistle when driving the train 'in reverse'.

The fireman would remain on the engine in order to stoke the fire and to take off the brakes, as the driver could only apply them.

Autotrains were being used by most rail companies in Great Britain by the 1920s, and were particularly common on branch line services.

They remained in widespread use until the 1950s and 1960s, when they were replaced by diesel multiple units (DMUs).
