Athearn - HO Scale - SD40-2 - DCC Ready - Rock Island (RI) #4791 - Red/White/Yellow (SKU 140-71532)

Available On: March 1, 2019

The SD40-2 was introduced in January 1972 as part of EMD’s Dash 2 series, responding to competing products from GE and ALCO. Reliability and versatility of the 3,000-horsepower SD40-2 made it the best-selling model in EMD’s history and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental SD45X and DDA40X. The last SD40-2 delivered to a United States railroad was built in July 1984, with production continuing for railroads in Canada until 1988.

Road Specific Features:

Rock Island bought its first six-motor freight power in 1973 in the form of eighteen U30Cs and ten SD40-2s. Although in poverty, and the Southern Pacific influence began to diminish, the Rock Island initially was luke warm to jumping on board with the SD40-2. Ordering a total of ten units, these locomotives were seen frequently in pool power on the Union Pacific and occasionally on the Southern Pacific too.
