The ALCO Century 415 is a diesel-electric locomotive of B-B wheel arrangement produced by the American Locomotive Company (ALCO) as part of their Century Series of locomotives.

The C415 is a large switcher locomotive or small road switcher locomotive equipped with a raised cab mounted slightly off-center, with a lower, narrower hood on either side. The longer one contained the diesel engine, a 1,500 hp (1.1 MW) eight-cylinder turbocharged Alco 251-F, while the shorter contained auxiliaries. The C415 could be ordered with three different cab heights; a low one for minimum clearances, a regular height one, and an extra-height one for maximum visibility.

Trucks fitted were either Type B standard road trucks or ALCO Hi-Ad (high adhesion) Type B trucks.^[1]

The locomotive was not very popular; 26 were built between 1966 and 1968 for seven different owners. The locomotive may still be in use. According to the November 2011 issue of Railfan & Railroad magazine, the Burlington Junction Railway owned three C415s numbered 21, 701 and 702.^[2]
