The ALCO C424 model was one of the first “Century-series” 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 models. 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. Erie Lackawanna, Canadian Pacific and National de Mexico purchased some of the largest fleets in their respective countries. By late 1964 ALCO had determined that an extra 100-hp did make a difference to some customers, and the 2,500-hp C425 model was the result. Improvements over the C424 included a higher capacity main generator, a simplified electrical control system, increased radiator capacity and an upgraded 251C prime mover. The appearance of the body was nearly identical to the C424, with one major exception being the addition of a bulge above the radiator intake grille at the rear of the long hood. A total of 90 units were produced between late 1964 and 1966, all for US roads. The largest purchases were made by Pennsylvania and Spokane Portland & Seattle.
