The GB&W had four Alco RS-2 road switchers on its roster.  They arrived in February 1952 and replaced steam power on third class freights.  By the 1970s these locomotives were used as yard switchers, but their days were numbered.  The Green Bay Route began a program to modernize its RS-3 fleet in the mid 1970s  with new engines, but problems with the arrangement of internal components prevented the same work from being done on the RS-2s and the railroad decided to dispose of the locomotives.  GBW #304 was the first to leave, going to the Michigan Northern Railroad in October 1976.

This undated photo captures the locomotive on a spring day in Wisconsin.  The engine had the simplified red and black scheme shown from the early 1970s until it left the railroad.  The faded GREEN BAY ROUTE herald is very similar to the condition it was in for a 1975 photo, so I would guess this photo may have been taken in the spring of that year.  The logo looks less faded in the reflection off the water than it does on the locomotive itself!
