The ALCO S-2 and S-4 were 1,000 horsepower diesel-electric switcher locomotives produced by ALCO and its Canadian licensee Montreal Locomotive Works, powered by turbocharged six-cylinder ALCO 539 engines. They differed mainly in trucks, the S-2 having ALCO Blunt trucks and the S-4 AAR type A switcher trucks. A total of 1,502 S-2s were built from August 1940 to June 1950, and 797 S-4s from June 1949 to August 1957, the S-4 first in Canada. Designed to replace older steam switchers in rail yards, they were a success, with styling by ALCO engineer Ray Patten using a mild application of Art Deco principles. A few are still in service on short lines and several are preserved.
