The Railmotors
After 1929, railmotors that provided the service were built on bus and truck chassis of the Associated Equipment Company (AEC). Buses in London had been built on the same type 506 chassis since 1914. Thirty-eight of the chassis were imported into Queensland from 1927-31, and fitted out with seats and bodies, and converted for rail use.
