PREORDER Atlas O 30138215 EMD SD70MAC 2-Rail Proto-Sound 3.0 Premier, BNSF #9687 | 679.95

This detailed AtlasO Premier EMD SD70MAC is based on road dieselsintroduced in the 1990s and operated by a number of railroads. In 1992,GM's Electro-Motive Division (EMD) introduced the new SD70 Series ofengines, which come in the standard direct-current (DC) andalternating-current (AC) models. One glance at the design of this enginereveals the enormous technological gains in railroading. The SD70 boasts a32-bit 16mHz control microprocessor named the EM2000. This computer workswith the Integrated Cab Electronics (ICE) system to collect, analyze, anddisplay a range of accurate-to-the-second information, such as speed, amps,throttle position, air brake operation, and cab signals. All of thisinformation is displayed on full-color liquid crystal displays that replacethe gauges and indicators found on earlier diesels. The 70 Series alsoemploys the HTCR (high-traction three-axle radial) truck that reducesrolling resistance in curves and lateral loads and therefore reduces wearon wheels. EMD estimates this will increase wheel life by 20 percent. Theseinnovations have led to brisk sales of both the SD70M (DC version) andSD70MAC (AC version). This O Scale replica comes equipped with ProtoSound 3and DCS for command control operation on DCC and standard DC layouts. TheSD70MAC offers a combination of detail, realism, and performance. Thisdetailed model features see-through fans and grilles, and a host of otherseparately applied metal details, plus a full LED lighting package. ThisSD70MAC is ready to run on your 2-rail O Gauge railroad. The SD70MAC is oneof many AtlasO locomotives.
