Source [] (original cite from 2000; link no longer exists) noted that RM production ended in 1966. Hollingsworth (1982) reported a design feature that is nearly unique, that of carrying the dry pipe (which conducts the steam from the boiler to the superheater) on top of the boiler in an insulated housing. A typical train of 600 tons would be pulled at 65 mph (105 kph).
