This detailed Atlas HO Scale Master Silver EMD GP40-2 is modeled after diesels introduced in the 1970s and operated by Class I and shortlines in the U.S. and Canada. 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. This Atlas model features details unique to each roadname and working front and/or rear ditch lights if appropriate. Other features include a five-pole, skew-wound motor with dual flywheels, directional LED lighting, Accumate(R) magnetic knuckle couplers, accurate decoration and roadname-appropriate body details. This sound-ready diesel comes equipped with a 21-pin DCC socket and speaker for easy decoder installation when you're ready. This EMD GP40-2 is one of many Atlas HO Scale locomotives.
