The first trolleybus route commenced operating on 1 October 1933 between
East Perth and
West Leederville station via
Wellington Street. It was the first permanent
trolleybus network in Australia,
Adelaide having commenced a trial service in May 1932. In 1938 it was extended along Cambridge Street to a balloon loop at Keane Street,
Wembley while in the same year, a new route to
Claremont via
Mounts Bay Road and
Stirling Highway was established replacing a
tram route. A branch from the Wembley route to the intersection of Grantham and Reserve Streets via Gregory Street was a new route not previously served by trams. In the late 1940s, it was proposed that trolleybuses replace tram routes to
Victoria Park,
Welshpool,
South Perth and
Como. However, overhead wires were considered an unsightly blight on the new
Causeway Bridge so motor buses were introduced instead. On 8 August 1951, trams were replaced on the
Mount Hawthorn line from
William Street in the city, The Claremont route was extended along Stirling Highway to the
Swanbourne fire station and Wembley routes along Louth Road and Dumfries Road to
Floreat Park. In 1959, trolleybuses replaced trams on the routes to
Mount Lawley, extending beyond tram territory to
Dianella via
Grand Promenade and to Bedford Park. In the same year, the Swanbourne route was replaced by motor buses in connection with road works associated with the interchange at the city end of
Narrows Bridge. The Mount Hawthorn route closed on 17 March 1963, the
Beaufort Street routes at the end of 1968 when
Barrack Street was made one-way northbound, and the remaining routes to Floreat Park on 29 August 1969. ==Fleet==
