EMD Demonstrator O Scale Premier SD70M Diesel Engine w/Proto-Sound 3.0 (Hi-Rail Wheels)

In 1992, GM's Electro-Motive Division (EMD) introduced its new SD70 series of third-generation, computerized diesels. The standard DC-motored version was the SD70M, while the SD70MAC offered AC traction motors - a technology that would later become the new standard for mainline diesels. One glance at the design of the new SD70 series revealed enormous technological gains in railroading.

The engines boasted a 32-bit 16MHz control microprocessor named the EM2000. This computer worked with an Integrated Cab Electronics (ICE) system to collect, analyze, and display a range of accurate-to-the-second information, including speed, amps, throttle position, air brake operation, and cab signals. All of this information was displayed on full-color LCD displays that replaced the gauges and indicators on earlier diesels.

The 70 Series also employed an HTCR (high-traction three-axle radial) truck that reduced lateral loads and rolling resistance in curves - increasing wheel life by up to 20 percent. By far the largest owner of SD70Ms was, and still is, the Union Pacific, which set a record for the largest single diesel order by purchasing 1000 engines - and later increasing the order by another 500 units. Production of the SD70M ended in 2004, as new EPA Tier 2 environmental regulations led to an upgraded design, the new SD70ACe.
