The Brisbane Tramway Trust was established under the "Brisbane Tramway Trust Act of 1922" to bring the management of Brisbane's tramways under government control. While the Trust first met on 4 December 1922, it formally acquired ownership and control of the assets of the Brisbane Tramways Company Ltd on 1 January 1923.
The Trust assumed control over the ownership, construction, maintenance and operation of tramways as well as motor and horse omnibus services in the cities of Brisbane and South Brisbane, the towns of Hamilton, Ithaca, Toowong and Windsor and the Shires of Stephens, Coorparoo and parts of Balmoral, Enoggera, Kedron and Toombul Shires. The Trust had authority to borrow money and to create by-laws with respect to tramways within its jurisdiction.
The Brisbane Tramway Trust was first constituted of 8 members - two appointed by the Governor-in-Council and 6 elected members representing the local authorities within the district of the Trust. Proposals for the future development of the tramway were required to be submitted by the Trust to an Advisory Board for approval by Governor-in-Council. The Advisory Board comprised one member appointed by the Governor-in-Council and two members nominated by the Trust. Operation of the tramway was managed by a General Manager who appointed engineers, surveyors, inspectors, clerks, motormen, conductors etc. The Trust's employees were entitled to appeal certain decisions of the Trust to an Appeal Board.
The "City of Brisbane Act 1924" created the City of Brisbane on 1 Oct 1925 by amalgamation of a number of local authorities, boards and public utilities and responsibility for the tramways was transferred to newly established Brisbane City Council. Accordingly the Brisbane Tramway Trust was dissolved on 1 Dec 1925.
