be run on petrol. They were lightweight at only 3.25 tons, though could carry up to 2 tons payload if required. The seating being easily removable to offer load space. In 1939, Motor Rail introduced the Motor Rail Dumper - a 4-ton, 2-wheel-drive dump truck (running on tyres rather than rails). It again used a Dorman engine, and a variant of the Dixon-Abbot gearbox. A working example (works number 8389 of 1947) with Dorman engine can be found at the Moseley Railway Trust. According to a 1955 advert, the diesel engine dumper had a capacity of 3 cubic yards, and had six forward gears and two reverse. It would carry a load of 4 tons up a 1 in 5 gradient. It was available with front control (driver at the front facing forward), or rear control (driver looking over the load, and hence with rear wheel steering, as is common modern practice). New models of this dumper for 1960 were the MR450 with 4.5 cubic yard capacity, reversible seat, and three speeds in either direction using a Dorman 37 bhp 2LB diesel engine; and the MR375 with 3.75 cubic yards capacity and 6 forward and 2 reverse gears which had a Lister 33 bhp HA3 air-cooled engine. Preserved locomotives Many Motor Rail products survive in preservation, and they are probably the most common make of narrow gauge locomotive still in existence in the United Kingdom.
