covered. As Jeff states, the master paint chips for diesels and
coaches were the same chip. Now the question is, did the motive
Indeed, the 1954 colour specification was known as Standard 92-G which
included all the railway standard colours for structures and equipment.
power shop people and the car department people source their paint
from the same sources? As noted in other discussions, this could
also make a slight difference in the colours.
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. And as Peter pointed out the
different departments may source their paint from different suppliers or
receive different batches.
Another change that can explain the differences or depth of colour is that
passenger equipment was given 3 coats of clear coat. This may give the
colour have some depth, possibly change the shade or enhance different
colour spectrum.
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.
Paint is a hard subject to make a definitive pronouncement about what's
what. More research is needed and hopefully our CP colours team can make
more headway on the subject too.
