This detailed HO Scale Atlas Master Silver Alco C425 is based on the later Century series of Alco road switchers produced for a number of railroads. Upgrades to the C424 later in production allowed its 16-cylinder 251B-series prime mover and improved electrical gear to produce 2,500-hp, keeping it as a direct competitor to the 2,500-hp GE U25B and EMD GP35 diesels. A total of 90 units were built between 1964 and 1966 for several railroads. The Alco C425 comes equipped with an eight-pin DCC socket for easy decoder installation when you're ready. Other features include a five-pole skewed-armature motor with dual flywheels, directional LED lighting, AccuMate(R) magnetic knuckle couplers, accurate decoration, roadname-appropriate body phase details and plenty of applied details.
