The S-class was a class of 18 trams built by Duncan & Fraser, Adelaide for the Melbourne, Brunswick & Coburg Tramways Trust (MBCTT). The first 12 entered service in 1916, numbered 1 to 12. All passed to the Melbourne & Metropolitan Tramways Board (MMTB) on 2 February 1920 when it took over the MBCTT, becoming the S-class and renumbered 154-165.[1] [2] [3]
The other six were built to a slightly modified design, being delivered to the MMTB between 1920 and 1922. Originally numbered 19, 20, 21, 139, 23, and 171, they were renumbered 166 to 171[1] [2] respectively and classed S1.[3]
In 1941/42, 14 were rebuilt for one-man operation, seven for the isolated Footscray network and seven for all night services on the main network. The Footscray cars were returned to crewed configuration in 1947.[1]
