| The ALCO Century 855 was ALCO's most powerful diesel-electric locomotive and, at the time, the most powerful diesel locomotive ever built. Powered by a pair of ALCO 251C diesel engines, and rated at 5,500 horsepower, it was ALCO's answer to the EMD DD35 and the GE U50. The trucks and bolsters of the 855 were similar to those under UP's earlier turbine locomotives. Only two A units and one B unit were built, all for Union Pacific Railroad, which had also requested double-engined locomotives from EMD and GE in order to replace the turbines, which had become uneconomical to operate. They spent their lives in the genereal freight pool at North Platte, however poor performance led to their early retirement and eventual scrapping by February 1972.|
