The X1-class was a class of ten trams built by the Melbourne & Metropolitan Tramways Board.
They were initially allocated to Glenhuntly and Hawthorn depots.
[1][2] Originally they were overhauled at Footscray depot, but from 1949 they were transferred by road to Preston Workshops.
[2][3] Four have been preserved: The two examples at the Walhalla Goldfields Railway are to be rebuilt and converted to narrow-gauge (760 mm (2 ft 5+15⁄16 in)).
461 will form the basis for a new railmotor for tourist traffic, with 463 (which is in worse condition) potentially to be rebuilt as a trailer carriage.
