Link to DERM trailers
VR's most successful railmotor to date, proven by their 63 year lifespan. Several railmotor types were tried over the years but a successful railmotor would elude the VR until this design, from the U.S. was put into service. The first one was assembled at Newport from parts provided by the St Louis Car Company in 1928. VR then built 9 copies.
They were originally driven by petrol engines and at that time called "PERMs" Petrol Electric Rail Motors. In 1952 they were fitted with 2 x General Motors 6 cylinder diesel engines and henceforth called "DERMs" Diesel Electric Rail Motor. In the late 70's RM 55 and RM 61 were extensively modified.
