Union Pacific applied this one-off livery, depicting the Stars and Stripes of the US flag, in 1994 as a fundraiser for the US-based charity, United Way. The locomotive operated as part of UP’s regular roster for many years. It also was spotted at various railroad events and photo ops across the United States.

During the 1980s, Southern Pacific and Santa Fe attempted to merge. Before the eventual merger denial by the ICC, the Santa Fe painted 306 locomotives versus Southern Pacific’s 96 locomotives. A total of sixteen SD40-2 diesels made it into merger colors before it was denied on July 24, 1986 by the ICC. After the merger’s denial, railroad industry writers, employees of both railroads and railfans alike joked that SPSF really stood for “Shouldn’t Paint So Fast”. These locomotives continued on in the “Kodachrome” scheme until the late 1980s.

    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.
