ALCO-S4 - Z scale  

The ALCO S4 are 1,000 horsepower (746 kW) diesel electric switchers produced by ALCO and Canadian licensee Montreal Locomotive Works (MLW). They use AAR type A switcher trucks, the same as for the EMD SW's. They are powered by ALCO 539 turbocharged, 6-cylinder diesels. The S-4 was constructed between June 1949 and August 1957 (MLW until 1957) with total sales of 797. Canadian production of the S-4 started more than a year before U S production of the S-4. ALCO did not start building the S-4 until August 1950.
