Originally built for the Santa Fe, this trio of RSD15s hauled countless tonnage for their original owners, and eventually several regional railroads in the upper midwest - the Lake Superior & Ishpeming, Fox River Valley Railroad and the Green Bay & Western. These units were on property when Wisconsin Central acquired the GBW and a couple were relettered but few saw serious running time before being scrapped.
