Double-decker bus
In George Town, Penang, five retired AEC C1-type double-decker trolleybuses were procured in 1956 by the George Town Municipal Tramways from London Transport as an experiment for the possible use of double-decker buses in George Town. Poor performance results and the advancing ages of the buses, coupled with efforts to replace the entire trolleybus fleet with single-deck diesel-powered buses in the 1960s, led to the withdrawal of the only double-deck buses in early Penangite public transport.
