Many railway companies adopted railmotors, or "motor cars" as they were described, in the early 1900s. These were single coaches with a small steam engine integrated. They were generally used with very basic stopping places with minimal facilities, and the aim was to enable the cheap establishment of passenger calls at locations where demand was low. The motor car stopping places were very short platforms, and suitable only because a single entrance and exit door in the vehicle could be controlled by the guard.
