The EMD SD18 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division between April 1960 and March 1963.[1] Power was provided by an EMD 567D1 16-cylinder engine which generated 1,800 hp (1.3 MW).[1]
54 examples of this locomotive model were built for American railroads,[1] and 60 for export, including fifteen for Korail (order numbers 700735–700749, serial numbers 28373–28387).
Design and Production[]
The SD18 was the third model in EMD's SD (special duty) line of locomotives. It was designed as a modified GP18 which had six axles instead of four. The additional axles allowed for more tractive effort and a more even distribution of weight compared to the GP18.[1]

Preservation[]
At least four SD18s have been preserved. Chop-nosed Duluth, Missabe & Iron Range 193 is now an operating member of the Lake Superior Railroad Museum collection. They also previously had DM&IR 316 in their collection, which is an "SDM"; an EMD SD18 given EMD 645 power assemblies by the Missabe, though still labeled as an SD18.[2] In 2019 #316 was traded for Northern Pacific #245 and left the museum for the Dakota Quality Grain Corporation in Parshall, N.D.
