Around 3000 vehicles comprised the RM family, 4 prototypes built in the mid fifties were followed from 1959
by production models through to the mid sixties. Later models were the 30 ft long RML type (2261 to 2760),
preceeded by 24 built in 1961, initially numbered ER880-903 and 43 Green Line coach versions -
RCL2218-2260 and one forward entrance bus - RMF1254. Earlier Green Line versions were shorter RMC1453
to 1520, plus prototype RMC4. The only other green Routemasters were from the later RML batch and
most ended up back in central London service, though some did see service for London Country in NBC
livery. The only other Routemasters built were 50 RMF types for Northern General, a batch of 65
forward entrance 'RMCs' for BEA/British Airways service and the prototype forward entrance Routemaster -
FRM1.
The Routemaster story will be a long running one with 40 year old plus vehicles currently being
refurbished by Marshalls for further service with new Cummins engines. Some Routemasters have
escaped to preservation, seen provincial service or escaped abroad. Some of the preserved and
provincial vehicles have ben recalled to the capital for further service in the city.
