MLW RS-10

The Montreal Locomotive Works RS-10 was a 1,600 horsepower (1,200 kW) road switcher built for the Canadian market. It was essentially an ALCO RS-3 in a redesigned carbody. It retained the RS-3's 12-cylinder Alco 244 engine. MLW built 129 of these locomotives before the model was replaced by the MLW RS-18.
