The ALCO Century 420 is a four-axle, 2,000 horsepower (1,491 kW) diesel-electric locomotive. 131 were built between June 1963 and August 1968. Cataloged as a part of ALCO's "Century" line of locomotives, the C420 was intended to replace the earlier RS-32 model. Since 2005, roughly 30% of C420 production exists. All units ordered by Mississippi Export, New York, Chicago & St. Louis Railroad ("Nickel Plate"), and Piedmont & Northern Railway have been scrapped. |
