Thanks, Ted. I had already checked out their site CN Lines SIG , but there's no info on rolling stock colours that far back. I did, however, go back to that site and send off a couple of e-mails to people who might have the information that I'm looking for. I'll post any info that I get, although with most of these organisations being staffed by volunteers, replies may take some time.

Anybody know what colour the CNR painted its gondolas and flatcars in the 1930s? I know that hoppers were black during this time, then changed to boxcar red in the early '40s. However, I can't find any info on other open cars.
