The GP40-2 was EMD’s follow-up to the very successful GP40 locomotive model. While many internal upgrades were introduced (such as the use of improved, modular Dash 2 electrical components), there were some external differences between the early production GP40-2 and late-production GP40. This included an engine water-level sight glass on the right side of the body (a feature common to all EMD Dash 2 models), a larger electrical cabinet air filter box, a lengthened battery compartment on the left side, and a slightly modified cab.

All GP40-2s featured a 16-cylinder EMD 645-series diesel engine which was rated at 3,000 horsepower. Early to mid-production phase 2 GP40-2s were built from mid-1976 through late-1979. Several major spotting features of Phase 2 units include: an 88” low nose, corrugated radiator grilles and notched step wells.

Included on this first production run are locomotives decorated for Southern Pacific and Cotton Belt. Our models will include several “signature” Southern Pacific spotting features including L-shaped front windshield, round brakewheel, operating cab gyralight, SP-style low nose headlight with non-operating red signal light and the related rear end “headlight package”. These models will also include a cab roof air conditioner and antenna platform with related piping.
