"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
        roundhouse.
        The Soo Line should've taken the hint on washing their power!"
