The Paddington tram depot in Brisbane, Australia was destroyed by fire on the night of 28 September 1962, one of the largest fires in Brisbane's history. Sixty-five of Brisbane's trams were destroyed. The destruction of the depot is generally seen as the beginning of the end for Brisbane's tram system, providing the justification for the subsequent closure of four tram routes and the gradual encroachment of bus operation on other tram routes, with the final closure of the tram system occurring on 13 April 1969.
The depot was constructed in 1915 on Latrobe Terrace, Paddington by the Brisbane Tramways Company to service its western suburbs routes. Initially the depot had 10 roads, but it was subsequently lengthened and widened to 13 roads.
It was on the side of a hill and was largely timber and corrugated iron panels. The front of the depot was at street level, but owing to the slope of the site, the rear of the depot was supported by a forest of timber supports, some over 50 feet (15 m) high.
It is believed that the fire started in a storage area underneath the depot, although the cause has never been fully determined. Around 7:30 pm depot staff were alerted by nearby residents who had noticed sparks falling from under the depot. Staff first secured the depot's cash in the depotmaster's car and then attempted to drive some trams out of the depot. Three trams were rescued before the fire cut the power to the depot. Firefighting was hampered by very low water pressure. As the fire progressed, burning trams periodically crashed through the weakened floor to the ground below. When it became obvious that the building could not be saved, firefighters concentrated on ensuring the fire did not spread to neighbouring homes. The fire, fuelled by tyres, oil and grease stored under the depot, was visible from many areas of Brisbane.
The loss of so many trams put considerable strain on the Brisbane City Council Transport Department. Trams allocated to the depot that were in service at the time of the fire were temporarily stored at the Tramways workshops in Milton. The City Council admitted that neither the trams nor the depot had been insured.
Initially, older-style trams were brought out of storage from other depots to assist with peak-hour demand, but in December 1962 tram services to Kalinga, Toowong, Rainworth and Bulimba Ferry (in the suburb of Newstead) were converted to diesel bus operation. These closures were the first significant route closures of the system and within 6½ years, the remainder of Brisbane's tram routes had been converted to diesel bus operation.
