ALCO S-2 (AS10 class) diesel-electric locomotive



The Alco S2 was the second model of switcher the company produced although it was constructed at the same time as the earlier S1. Two of the significant differences between the two models was the increased horsepower and the "Blunt trucks" used by S2. Like its S1 sister, the Alco S2 was first produced in 1940 featuring an end-cab design using McIntosh & Seymore's 539 diesel engine and was built between August 1940 and June 1950, with a total of 1.462 units completed. The Pennsylvania Railroad purchased between 1948-1950 42 engines. Later, other upgraded versions were built, such as the widespread S4, built in about 650 units.
