This detailed HO Scale Atlas Master Silver Alco C424 is based on the later Century series of Alco road switchers produced for a number of railroads. One of the first Century locomotives to be produced, its 16-cylinder 251B-series prime mover produced 2,400-hp, making it a direct competitor to the 2,500-hp GE U25B and EMD GP35 diesels. A total of 190 units were built between 1963 and 1966 for customers throughout North America, including 53 for roads in the US, 92 for Canada and 45 for Mexico. The Alco C424 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.
