Overview

William Bridges Adams started building railmotors as early as 1848, but only in small numbers. One example was the Bristol and Exeter Railway Fairfield steam carriage.
Around 1900, because of competition from road vehicles and electric trams, there was renewed interest in railmotors and several railway companies, including the London and North Western Railway, Lancashire and Yorkshire Railway, and Great Western Railway began to introduce them.

Designs

There were two basic designs:

★ A small 0-4-0 steam locomotive with one end of a coach hung on it like a semi-trailer.

★ A coach with a steam engine built into one end of it. This type would sometimes have a vertical boiler.
These machines were not a great success because they lacked flexibility. Most could haul a single trailer, but no more, so they could not cope with peak demands. For this reason, they were largely superseded by push-pull trains and the GWR converted some of their railmotors into autocoaches for this purpose.
In the late 1920s there was another revival of railmotors with the introduction of new designs from Clayton and Sentinel with high-speed engines. The London and North Eastern Railway bought over 80 of them but, again, they were short-lived. Some lasted no more than 10 years and all had been withdrawn by 1947.
In the 1950s the diesel railcar made great progress and the railmotor was consigned to history. The diesel's ability to use multiple unit control was a huge advantage.
