PROTOTYPE SPECIFIC INFORMATION

The SD40 had 3,000 hp from a turbocharged V16. 856 examples of this locomotive model were built for American railroads, 330 were built for Canadian railroads, and 72 were built for Mexican railroads.

Southern Pacific - 1984 Games

Southern Pacific instituted a rebuild program for their SD40s in 1980-1981. The units were updated to Dash-2 electrical standards, as well as receiving electrical cabinet air filters just behind the cab on the fireman’s side. They were placed in the 73XX number series.

The Southern Pacific Railroad was an official sponsor of the 1984 Summer Games in Los Angeles, CA. The games were promoted with a special paint scheme applied to SD40R #7347. We have included the gold-painted Nathan P-3 air horn, bell, and the “1932” and 1984” numberboards, which indicate the years that the games were held in Los Angeles. This offering is a great starting point for replicating this historic unit.
