The E-class was a group of 10 trams built by Duncan & Fraser, Adelaide, for the Prahran & Malvern Tramways Trust (P&MTT) in 1914, numbered 36 to 45.

All retained their fleet numbers when passed to the Melbourne & Metropolitan Tramways Board (M&MTB) after it took over the P&MTT on 2 February 1920, and they were designated E-class sometime after October 1921.

The 22E Maximum Traction trucks were of JG Brill design, although manufactured by Brush in England.

All others, with the possible exception of number 40, were overhauled and had their rear doors blanked-off for service during World War II.

In the second quarter of 1951, all remaining eight cars were sold to the SEC for use in Ballarat, Bendigo, and Geelong.
