The EMD SD18 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division between April 1960 and March 1963. Power was provided by an EMD 567D1 16-cylinder engine which generated 1,800 hp (1.3 MW).
54 examples of this locomotive model were built for American railroads, and 60 for export, including fifteen for Korail (order numbers 700735–700749, serial numbers 28373–28387).
There are at least four SD18s that have been preserved.
Trivia[]
- There were 114 engines that were built.
- 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.
