1952-54 was a transition period with regards to paint technologies. CP
switched from DuPont Duo lacquer to enamels made by Mason and DuPont.
Possibly diesels manufactured in the US used a different paint
supplier than
CP and that accounts for some difference...
Unless CP specified otherwise, EMD's standard painting practice was to
use DuPont Duco nitrocellulose lacquer for the body colors, and DuPont
Dulux alkyd enamel for everything below the bottom of the body,
trucks, fuel tank, pilot, etc. This is because the Dulux, while a
softer finish, was more chip resistant, I'm sure.
I'm not entirely sure that diesels received the same clear coat
treatment
either. I checked two GM paint diagrams, for the FP-7 and E8's, and the
paint bill of materials doesn't list clear coat. There isn't any note
saying that this had to be done. Possibly clear coat was a standard
practise and it wasn't needed to be noted.
If it wasn't on the styling drawing, I suspect it wasn't done. The big
selling point of the DuPont automotive finishes (both Duco and Dulux)
when they were introduced in the thirties is they didn't need clear
coating.
I've declined to comment on the CP colors, as my area of interest is
the Soo Line, but I noted that someone again mentioned that the CP
chose its maroon to match the Soo passenger cars, which is
interesting, because the Soo didn't. All the road deisels the Soo
ordered from EMD during the late forties and early fifties came
finished in the same Duco maroon, which as far as I know, the coach
shop didn't use, as they weren't equipped to spray paint. The coach
stock was painted with a series of different brushable maroons over
the course of time that kinda, sorta matched, but didn't particularly
match the color on the locomotives. I know that sample cards from the
Shoreham coach shop still exist, I've seen them, but were marked only
with the maker's name, not the color code. This difference in color is
always very evident in color photos of Soo Line trains, especially
since the head end cars tended to be the most faded in the consist. So
this begs the question, if the CP matched their color to the Soo
coaches, which of the coach colors did they match to?
Let's at least start to put this to rest. You seem to have a copy of
the CP FP-7 styling drawing close at hand, and I have a copy of the
same for a Soo FP-7. The drawing for the Soo engine specifies Duco
254-34460 for the maroon, and Duco 254-54292 for the imitation gold,
along with black Duco for the carbody end and striping, and black
Dulux for the trucks and fuel tank. Are either of these numbers in
common with those on the drawing for the CP unit?
