The RLH

AEC Regent III low-height double-decker
 
In addition to the introduction of the standardised RT family, London Transport also had a requirement after the war for low-height double-deck buses for routes where the 14'6"-high RT could not be used.  In order to replace a miscellany of older vehicles, London Transport purchased 76 of the RLH class in 1950-52.  The RLH was essentially provincial in design, with a body built by Weymann of Addlestone, Surrey, on the standard AEC Regent III chassis.  The 13'6" height was achieved by setting the upstairs gangway to the side and lowering it over the heads of the offside passengers downstairs.  Mind your head if you ride on an RLH!
 
The buses were used both in the Country and Central Areas, and occasionally green buses were borrowed by the Central Area to cover for buses being overhauled.  Only four Central Area garages ran the RLH, including Dalston for route 178.  This route saw the last operation of the RLH by London Transport, on 16 April 1971.
