Leichhardt Tram Depot was built as a twelve road depot on the corner of William Street and Derbyshire Road, Leichhardt, being available for use on 22 June 1915. It was never used as an operational tram depot, instead being used to store trams. It was converted to a bus depot in 1937. It was also the central maintenance facility until the
Chullora Bus Workshops opened in 1958. The old tramshed is used as part of the new expanded Leichhardt Bus Depot while the
Sydney Bus Museum occupies the northern bays after its relocation from
Tempe Bus Depot. Both the former Cable Stores Building and Traffic Office (also known as the Tram Depot Office) was proposed as part of the cancelled Leichhardt Police Station development. The depot is also home to the
Roads & Maritime Services barrier transfer machine that moves the central barrier on
Victoria Road between the
Gladesville and
Iron Cove Bridges. As part of the contracting out of
region 6, operation of Leichhardt depot passed from
State Transit to
Transit Systems on 1 July 2018. In February 2026, it had an allocation of 192 buses. ==Design==
