"This shot of #313 shows a few details not typically associated with
the GB&W: A snow shield over the air intake behind the cab (never
saw this before on any GB&W Century); the white line-up mark"
beneath the turbocharger on the hood, something generally thought to
have been put on the locos by GB&W mechanical forces later in the
1970's-early 1980's for use in lining up the turbo stack when
reinstalling a "rested" 251 prime mover.
I've debated weathering the trucks like this on my models of GB&W
power. Truthfully, back in this period, the GB&W was quite
particular about how clean their engines were kept; I don't recall
seeing the trucks get quite this dirty, not until Itel began cutting unnecessary
expenditures late in the GB&W's life.
By that time, everything was solid red.
Seems to me, the GB&W used to scrub their power at least
once per week as part of regular maintenance. There was a photo by
Stan Mailer, I think it was, that appeared in Trains magazine some
number of years back of a mechanical department employee of the GB&W
pressure washing one of the units at Green Bay, I think inside the
The Soo Line should've taken the hint on washing their power!"
