The 1800 class railmotors were a class of self-propelled railmotors built by Commonwealth Engineering, Granville for the Queensland Railways. History In 1949, the Queensland Railways placed an order for 12 aluminium two-carriage 1800 class railmotors with Commonwealth Engineering, Granville. Each set comprised a power car (RM – "Rail Motor") and trailer car (TP – "Trailer Passenger"). The railmotors seated 55 passengers and were delivered to Queensland Railways between 1952 and 1954. Preservation Two trailer carriages remain in service on the Gulflander, operating between Normanton and Croydon, and one motor car is preserved at the Rosewood Railway Museum. The bodies of four others are privately owned. Gallery Summary References Railcars of Queensland
