1908 built steam railmotor No.93 arrives at Didcot Halt, in the Didcot Railway Centre on 5 May 2013, after a trip along the short demonstration line. This unique vehicle had just been paired up with autotrailer 92, effectively making the world's only steam multiple unit (SMU?). 93 was itself converted into an autotrailer in 1934, after the steam railmotor experiment was abandoned. It was withdrawn in 1956, but survived for a number of years as a departmental vehicle.
