MidContinent Railway #7, a S-1, rests between trains on October 10, 2004.
The ALCO S1 and S3 were 660 hp (490 kW) switcher diesel locomotives produced by ALCO and Canadian licensee Montreal Locomotive Works. The two locomotives differed substantially only in trucks, with the S-1 using Blunt trucks and the S-3 riding on AAR type A switcher trucks. The S-1 was built between April 1940 and June 1950, with a total of 540 completed, while the S-3 was constructed between March 1950 and November 1953 (MLW until 1957) with total sales of 292. A modified version, the S-10, was built by MLW only; 13 were built between January and June 1958.
Identification
The S-1 and S-3 are distinguishable externally from the very similar S-2 and S-4 1,000 hp (750 kW) switchers in that they have a smaller exhaust stack with a round base and a smaller radiator shutter area on the nose sides. The S-1/S-3 radiator shutter area is taller than it is wide, while the S-2/S-4 radiator area is wider. The smaller stack is due to the lack of turbocharging.
As mentioned above, the S-1 and S-3 are only differentiated by trucks. The S-10 is not externally distinguishable from later Canadian-built S-3 locomotives; it differs mostly in electrical equipment.
Original owners
The S-1 and S-3 sold to an extensive list of railroads and industrial operators, as detailed below. Major S-1-owning railroads included the NYC with 71 locomotives; the New Haven with 65 locomotives; the L&N with 45 locomotives; the C&NW, with 29 locomotives; and the Pennsylvania Railroad with 27 locomotives. Major customers for the S-3 included the CP, with 101; the CN, with 49; the NYC, with 43 locomotives; the B&M, with 16; and the PRR, with 13. The MLW S-10 sold only to the CP.
The totals below include export orders and MLW-built locomotives.
