The American Locomotive Company's famous low hood switchers were built at the Schenectady Works from 1940 to 1960. They spent most of their careers classifying freight for Class I railroads, but occasionally ventured out onto the mainline to power locals or to switch passenger trains at stations. Though most of these switchers have met the scrapper's torch, some still survive today after a half century of service, growling away on shortlines and industrial rails. The all-new, fully featured Lionel ALCo S-2 and S-4 switchers offer prototypical paint schemes, authentic engine sounds from the RailSounds sound system, and the power of the TrainMaster Command Control system.
