Routemaster prototype FRM1

English: The Routemaster prototype FRM1 (reg. KGY 4D) was an attempt by London Transport, in collaboration with AEC and Park Royal, to develop a rear-engined version of their front-engined bus, which was already in service in London. This was in response to staff shortages, and the gradual conversion of fleets outside London to other rear-engined models which, unlike the Routemaster or older rear platform designs, could be operated by just one person, who acted as both driver and conductor. Development began in 1964, by which time nearly 1,800 Routemasters had been delivered. FRM1 was delivered to London Transport for trials in July 1966. It didn't lead to any further orders however, and London Transport instead opted to develop the Leyland Fleetline. FRM1 continued in normal service as a unique bus. By January 1978 it had been transferred to sightseeing duties. It was finally withdrawn in February 1983, joining the London Transport Museum collection in April. In 1998 it was transferred to the museum's Acton depot. [1].
