The EMD GP40-2 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division as part of its Dash 2 line between April 1972 and December 1986. The locomotive's power is provided by an EMD 645E3 16-cylinder engine which generates 3,000 horsepower (2.24 MW).

Production

Standard GP40-2 production totaled 861 units, with 817 built for U.S. railroads, 44 for Mexican railroads. Furthermore, 279 GP40-2s were built by General Motors Diesel (GMD) between 1974 and 1976. In addition, three GP40P-2s, passenger versions of the GP40-2, were built in 1974. Total production of the GP40-2 and its variations totaled 1,143 units.[citation needed]

Performance

With the 62:15 gearing (65-70 mph maximum) EMD rated the GP40-2 at 55,400 lb continuous tractive effort. Some had PF21 module that reduced the output below 23 mph, lowering continuous speed down to 11 mph.[citation needed]

Rebuilds

Union Pacific has rebuilt 129 of their GP40's and GP40-2's into GP40N's at their Jenk's shop. These units received a microprocessor control system to increase adhesion, control options, and extend the life of the locomotive.[2][3]

CSX has rebuilt only one GP40-2 locomotive, numbered 6041 (originally BO 4141), into a hydrogen fuel cell locomotive in collaboration with CPKC on April 16, 2024. The unit's road number is 2100, and classified as GP38H2.[4]

Preservation

• Sonora Baja California 2107 is now preserved in a Museum in Mexicali, MX [citation needed]
