Intended as a replacement for the EMD GP7, EMD GP9 GP9, and EMD GP18 GP18 models, it is generally employed as a classification yard yard switcher or light road switcher. This locomotive is powered by a 12-cylinder (engine) cylinder EMD 645E engine, which generates 1,500 horsepower (1,119 kW). The GP15-1 shares a frame with many other early '''EMD GP series''' locomotives, giving it an overall length of 56 feet 2 inches. A total of 310 units were built for United States American railroads. The Missouri Pacific Railroad purchased more units than the other three buyers combined. For spotting purposes, the MP models have a number of visually-distinguishing features, though not all were applied consistently to the MP units: * The MP units have a grab iron ladder mounted on both sides of the long hood end; * MP's initial order of GP15-1s rode on Blomberg M trucks rather than the more common Blomberg B (all subsequent units were delivered with Blomberg B trucks) — and, while the standard Blomberg B truck carries two brake shoes per wheel, many MP units were equipped with only a single brake shoe per wheel; * #1555–#1574 were outfitted with the standard 81" nose, while the remaining units (all built in December, 1976 or later) came with an 88" nose; and * The radiator section is similar to those found on the EMD SD40T-2 and EMD SD45T-2 "tunnel motors," leading some observers to incorrectly identify the units as such. A number of GP15-1s remain in service today.
