Atlas Premier O-Gauge NYC S-2 (3-Rail) Pre-Order

The ALCo S-2 and S-4 were 1,000-horsepower (746 kW) diesel electric switchers produced by ALCo and Canadian licensee Montreal Locomotive Works (MLW).

Powered by turbocharged, 6-cylinder ALCo 539 diesel engines, the two locomotives differed mainly in their trucks: the S-2 had ALCo "Blunt" trucks; the S-4, AAR type A switcher trucks. A total of 1,502 S-2s were built from August 1940 to June 1950; 797 S-4s were built from June 1949 to August 1957. The S-4 was first produced in Canada, with ALCo production beginning in June 1949.

The S-2 and S-4 were designed as rail yard switchers, meant to replace older, less efficient, and more demanding steam switchers.They were a success, with many remaining in service today.

The locomotives' exterior was styled by ALCo engineer Ray Patten, who used curves in a mild application of Art Deco principles.

The S-2 and S-4 are distinguishable externally from the very similar S-1 and S-3 660 hp (492 kW) switchers in that they have a larger exhaust stack with an oblong base and a larger 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 larger stack is due to turbocharging. The carbody and cab of late S-2s are nearly indistinguishable from those of S-4s. Hence, a truck swap can cause many to misidentify a unit.
