The MLW RS-18 was an 1,800 hp (1,340 kW) diesel-electric locomotive built by Montreal Locomotive Works between December 1956 and August 1968. It replaced the RS-10 in MLW's catalogue, and production totalled 351 locomotives, to eight customers.

MLW also introduced the 251B engine in late 1956 and put the 12 cylinder 1800 hp version in the RS-10 carbody to produce the uniquely Canadian RS-11M (later renamed RS-18). CN purchased 131 units between 1956 and 1958 and numbered them 3615-3745 (MR-18b, c, d).
