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).
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 have DM&IR 316 in their collection, which is an "SDM"; an EMD SD18 given EMD 645 power assemblies by the Missabe. However, it is still labeled as an SD18.
The South Branch Valley Railroad also regularly operates former Bessemer & Lake Erie SD18 853 as their 182.
A fourth unit is Chesapeake and Ohio 7311, in Chessie System colors and with VLIX reporting marks. It was sold to a company in the State of Washington and is slated for a complete rebuild. As of now the unit has been running freights but should be rebuilt soon.This SD18 rides on Alco trucks.
Additionally, both SD18s owned by the Chicago & Illinois Midland are still in operation, and are used by the Illinois Midland Railroad, the successor to the CIM.
