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 16 cylinder ALCO 251C diesel engines and rated at 5500 hp (4101 kW) it was ALCO’s answer to the EMD DD35 and the GE U50. The C855 rode on four two-axle trucks grouped in pairs linked by span bolsters giving a wheel arrangement of B+B-B+B. The trucks and bolsters were similar to those under UP’s earlier turbine locomotives.
