Originally a tram depot (Camberwell) but was renamed Walworth to avoid confusion with the existing (Q) garage on 6 October 1951 upon conversion to motorbus operation. The garage was closed in November 1985 but was temporarily re-opened on 15th August 1987 for the Red Arrow services until Waterloo (RA) was made ready.
