s for the Canadian National Railway (CN). The base RS-18 model was derived by MLW from the ALCO-produced RS-11 model, and was equipped with a 12-cylinder four-cycle model 251B diesel engine rated at . This engine turned a General Electric (of Peterborough, Ontario) DC generator feeding four traction motors - one per axle on two bogies. Many RS-18s were equipped with so-called "light" trucks (made by Dofasco and others) in deference to light rail on Canadian branchlines. RS-18s were owned by Canadian Pacific as well as Canadian National and many other Canadian railways, and continued in service on major railroads into the 1990s. They continue in branchline and secondary service throughout North America today (April 2009). Using the RS-18 as a starting point, the RSC-14 was created in the mid-1970s to meet CN's requirement for A1A-A1A trucked locomotives for light rural branchline service, particularly in the
