HO SD40 Locomotive with DCC & Sound, Kansas City Southern #631 Overview
During the 1970's and 1980's, KCS adapted a simplistic, yet very noticeable scheme on their freight diesels. Ordered from EMD in 1971, these later phase SD40's were the backbone of the fleet next to their SD40-2 brethren.
In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. 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.
