Freight cars for a CN F7A in zebra stripes?

Another thing to consider is whether the cars are models of those built in the '40s or those in use in the '40s. Many boxcars built during the war years 1939-45 (1941-45 in the U.S.) were of composite construction, and a lot of them were either rebuilt or replaced after the war. Similarly, cars built prior to the war were, for the most part, worn-out by war's end, and were scrapped when new car construction resumed. The Pullman-Standard PS-1 40' boxcar was introduced in 1947, and construction continued until 1961, albeit with visible improvements. During the '50s, 50' and longer cars started to become common, and with increased mechanisation of loading (forklifts), wider door openings were required.
Still, as I mentioned, it's your railroad, so"run 'em if ya got 'em". I'm modelling the late '30s, but have no compunction about running a few favourite cars that didn't exist until the '40s or even '50s. The "proto police" have no jurisdiction in my layout room.
