Early trolleys were powered by a vee-twin JAP engine with a friction drive, later trolleys were powered by motor car engines from Ford such as the 4-cylinder E93A which was used in the Ford Anglia, and were fitted with a gearbox. The trolleys could also haul trailers containing equipment. 

Although no longer used by Network Rail, many have been preserved and are used by preserved railways for the same role intended on the mainline.
