The class O2 are almost mechanically identical to the original class O motors, except that (a) they use trolley pole pickup instead of a pantograph, and (b) they run under 1500 vdc.

Electrically they’re identical; the multi-system power circuit was originally designed to take 600vdc (from third rail) so it was easy to reconfigure to take 600/1500/3000 instead of just 600/3000.

Four have been built for the ORRC; 1079 in Toronto Suburban Railway colours, 1080 in the Hamilton & Brantford’s, and 1487 & 1489 in Lake Erie & Northern colours.
