US Army LEGACY Alco S2 #7100 One of Alco's most successful designs, the S2 switcher found a home in many industries and railroads of all sizes. Like cats with 9 lives, many of these rugged switchers have worked for multiple owners, and dozens survive today. This year's run includes a great variety of new road names which show some of that prototypical diversity. From private industry to class one railroads and government agencies, these Alcos have moved everything from soybeans to spaceships! With a proven single motor drive, these models can handle anything your railroad needs as well.
