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.
