HO RTR SD40-2 with DCC & T2 Sound, KCS #639 Overview

During the 1990's, KCS began repainting some of their SD40-2's in this grey scheme with yellow stripes. KCS also added nose mounted gyra lights and moved the horn to the back of the units. They could be found all over the system.

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 like 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.
