AEC Regent RTL501 JXC20 (1949) in Red (1:24 scale)
- Traditionally, AEC was London Transport"s major supplier of buses but, at the end of the war, it became apparent that they had insufficient capacity to meet the future dem&. So, in the summer of 1946, Leyland Motors Ltd was approached to supply 1, 500 of its new standard 9.8 litre engine, 1, 000 for RT"s which would now be called RTL"s & the remaining 500 for RTW"s, the wider-bodied version.
RTL501 was the first Leyl&-engined RT to enter service on 16th June 1948, operating from Turnham Green garage on Route 91. Easily recognisable by its Leyland radiator grille which did not have the AEC-style central vertical silver strip, its Leyland chassis also has the characteristic flat-faced Leyland dumb-irons. RTL501 is also unique because it was also the only Leyland to be fitted with a roof box from new, since it used the RT3 body originally destined for RT657.
