I recently acquired 5 Intermountain 40 ft CN "wet noodle" boxcars. Fixing them up, I (finally) noticed that they say "CANADIAN" on both sides, instead of having the French version on one side. As most picture sites only show one side of a car, this MAY be right, but seems unusual. These cars are in the 5375xx - 5383xx series.
Were any of these painted with the same name on both sides, or were the IM designers lazy? I'd try to fix them, but finding an "E" that would match the printed names seems to be a lot of work.
Looking through my few CN boxcars, it seems that the only models I have that DO have the French lettering are one MT car, and the cars I lettered with CDS dry transfers.
