"I have to agree with John Campbell... I think the red and gray looks
        best on the RS-2s & RS-3s.
        Interesting to note: The GB&W was constantly upgrading their
        Alcos. As delivered, all of the RS-2s & at least #305 and #306 of
        the RS-3s came with single beam headlights, later converted to twin
        sealed beam retrofits inside the old single beam casing, then to the
        headlight shown on #308 here. All the RS-2s came with louvers on the
        doors, (possibly #305 and #306 as well) and GB&W later retrofitted
        these units with the bare carbody filters shown here. Even the two S-1
        switchers and the S-2 received the bare carbody filters!
        Also: Although they were still Alcos, the RS-3s as rebuilt into
        RS-20s kinda left me with a bad taste in my mouth. Maybe it was that
        chopped short hood. Milwaukee Road did that with four RSC-2's, but the
        result wasn't quite as esthetically insulting as the GB&W's
        rendering of the chopped short hood."
