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 .
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.
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.

Rebuilds
Union Pacific has rebuilt 129 of their GP40's and GP40-2's into GP40N<nowiki/>'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.
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. The railroad also rebuilt a handful of GP40-2 into GP40-3s, which features new cabs, new electronics, and other internal differences.
Preservation
Sonora Baja California 2107 is now preserved in a Museum in Mexicali, MX.
