I have a color photo of a C&NW Viking roofed box car and it
toggle quoted messageShow quoted text
appears that the roof was unpainted galvanized metal but has
gradually oxidized (rusted). There appears to be no paint on
the APEX running board either (CNW #77866). The "seam caps"
have the same appearance as the rest of the roof, partially
oxidized, so this makes me think they were initially also
not painted. By contrast, many other roofs show painted
seam caps that contrast with the unpainted roof panels.
For some reason, finding overhead shots of Viking roof cars
in color has been difficult!
Mark and Tony,
The Viking roofs on the CNW emergency box cars were indeed galvanized.
Also, I believe InterMountain made a good decision on the roof color
based on available data (see below). InterMountain could have gone the
easier route and painted the roof the same as the rest of the body.
That would have eliminated a masking step and saved cost. Instead, IM
masked the car so that the roof could be painted what is thought to be
a legitimate color based on interpretation of source data by multiple
people, including noted CNW freight car historian Jeff Koeller.
I have the original bill of materials for the CNW cars built by
Pullman-Standard having the Viking roofs. I scanned and sent a copy of
the paint specs to both InterMountain and Jeff so they had actual
documentation from which to base a decision. In the paint
specifications it designates the outside of the roof and running boards
as being painted with two coats of Sherwin-Williams #21572 or equal
Galvanized Roof Paint.
Naturally, the discussion then led to "OK, now what color is
"galvanized roof paint?" Ultimately it was decided that the color
should be a shade of gray somewhat matching that of the galvanized roof
itself. Everyone is free to debate the conclusion, but the decision was
made with a great deal of thought. The sides, ends, and trucks of the
cars received CNW #1 paint "redish-brown in color." Underframes were
coated with black car cement. White stencils.
I have been known to criticize some of InterMountain's models when
think the criticism is valid and deserved, In this case, IF a mistake
in the roof color was made, I wouldn't characterize it "another
InterMountain goof" since a great deal of discussion and thought went
into the decision.
The Viking Roof specification in Pullman-Standard lot no. 5752 called
for roof sheets #16 U.S. Ga. C.B. Galvanized. Standard Railway
Equipment Manufacturing Co. drawing 7R-2650-C. The P-S drawing list
gives the general arrangement drawing no. 58215-C. It's quite possible
this drawing is in the Pullman collection at the Illinois Railway
At the same time AC&F built emergency box cars for CNW (and one car for
CMO), and the bill of materials for the galvanized Murphy roofs on
these cars specified them as unpainted. Hope this helps.
