Harrow Weald is another suburban garage which has always been associated with Routes in North West London and apart from N18 has never operated in Central London. The RT was predominant in the fifties and sixties although RF for the 136 and RLH for the 230 were also operated from HD. Routemasters were not introduced until 1978 although originally they were planned to go to Harrow Weald in 1959 but due to union objections this never materialised.
In 1987 the Harrow Bus Scheme was introduced and the buses at Harrow Weald were given a new Red and Cream livery and called Harrow Buses.
Harrow Weald is now part of the Metroline group.
