HO RTR SD40-2 with DCC & T2 Sound, ATSF #5067 Overview
Starting in the late 1980s, Santa Fe began to modify their locomotives based on crew feedback. The headlight was moved from the cab to the nose to reduce the amount of glare. The air horn was also moved to the long hood to reduce the amount of noise intrusion into the cab. Not all locomotives were modified at the same time, but by the 1990s many had been modified.
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.
