Commonwealth Edison EMD SW-1200 16, built in 1964, switches at the Plaines Generating Plant near Joliet, Illinois, now the Joliet Station of Midwest Generation. In this late 1960s photo provided by Gary Thompson the locomotive has no engineer; coupled to it is a remote control car which was, in turn, worked by an operator at the facility's car dumper. Around 1970 the remote control system was abandoned and the locomotive was operated manually from its own controls. As of 2020 this unit, actually owned by Relco, was still on the property but had been out of service for a decade; stripped for parts, its awaited an uncertain fate. At that time the plant was using another leased unit but had been testing a GenSet unit from National Railway Equipment Co. (NREX). This information came from Wilbert R. Harrison, Operations Supervisor-Fuel at the Joliet Station, who at one time operated and maintained No. 16.
