British United Traction (B.U.T.)
British United Traction (B.U.T.) was formed in 1946 upon the amalgamation of the trolleybus building activities of both A.E.C & Leyland. It continued production until about 1964.
This is a B.U.T. single-deck trolley bus with PRV bodywork (Body Nos. B34476-84). The first of nine delivered to Montevideo, Uruguay in 1950/51. This might have been exhibited at the 1950 Motor Show.

B.U.T. built diesel engines (rebranded AEC) for railcars. Here this PRV bodied prototype (79742), with its AEC underframe and BUT/AEC engine, is seen at Watford Junction. Whereas the earlier PRV bodied GWR railcars became affectionately known as "the Flying Bananas" these BUT/AEC/PRV units gained the less attractive nickname of "the Flying Bricks"; and the reason does seem obvious (see more in the Railbuses pages).
