EMD SD70ACe

The SD70ACe, built in the United States between 2004 and 2014, was introduced as the successor to the SD70MAC. Designed to meet EPA Tier 2 emissions regulations, the model later evolved in 2012 to comply with Tier 3 standards. Powered by EMD’s 16-710-G3C-T2 prime mover, the SD70ACe produces 4,300 horsepower, with later Tier 3 versions boosted to 4,500 horsepower. These locomotives deliver 157,000 lbf of continuous tractive effort and 191,000 lbf at starting, with braking effort rated at 106,000 lbf.

While mechanically similar to earlier SD70 models, the SD70ACe features a redesigned underframe and new sheet metal construction. Its electrical cables and air lines are routed beneath the walkways on opposite sides, improving maintenance access. The design continues trends from the SD80 and SD90 series, including a wide radiator nearly matching the cab’s width, a lowered center hood section, and dynamic brakes relocated to the rear. The cab itself was derived from late-model SD90MAC-H units, featuring rectangular window glass and a distinct external appearance compared to earlier SD70M and SD70MAC cabs. In 2008, EMD standardized the isolated cab design for new SD70ACes after non-isolated versions were restricted from leading BNSF trains due to excessive vibration.

In this production run, we’re offering models in eight distinct paint schemes—seven of which are prototypical. Highlights include KCS 4006 Veterans Day Salute, Norfolk Southern 1080 (the D&H Heritage unit), and Union Pacific 1943 “The Spirit”.

Each locomotive is tooled with detail variations specific to its prototype, including low and high headlights, isolated and non-isolated cabs, long and short sunshades, two brake wheel styles, three cab roof designs, and two blower vent layouts.

Models are available with Paragon4 Sound/DC/DCC or in our No-Sound / DCC-Ready option.
