|Some of the more unique power to ever ride on GBW rails had to be the
ex- Lake Superior & Ishpeming RSD-15s.
In 1989, the Green Bay and Western bought out the Lake Superior and
Ishpeming's fleet of six RSD-15s as well as the railroad's entire stock of Alco
parts and tools (the Alco RS-27 was the four-axle equivalent of the
RSD-15 and shared many parts). These engines were the only
six-axle diesels ever owned by the Green Bay Route.
It is a common belief that the GB&W intended to cannibalize these
locos for parts to keep their own fleet of Alco locomotives going strong
- but the G B W repaint on the sides of the long hood of the
RSD-15s makes a
person believe that at least some of the six engines were destined for
revenue service. Rumors have them operating east to Kewaunee, but
there doesn't seem to be any photo evidence of them going any further than the Wisconsin Central
interchange at McDonald Yard, a few miles north of
Norwood Yard, while on the GB&W..
The engines soon wound up with sister railroad Fox Valley
& Western instead as as extra power for Green Bay to
Milwaukee trains. A few trips proved that the locomotives were
unreliable in regular service and they soon went to the Wisconsin Central's
North Green Bay roundhouse (former C&NW) where they were scrapped in
