@StevefromPA - Steve thank you for your comment on my Gatekeeper's House. I really liked the/ tinplate you posted. The American Market Marklin passenger cars and box car are really neat. Personally, after pre-war stuff I am partial to Marx and the GE 70 tonners you posted are neat, the WP from '72-'74 and the ICG from '74-'75. OBTW in case you didn't know the ICG is pretty much a single variation (reverse or non reversing) but the WP came in 2 or 3 other color schemes (Green / yellow and Green/cream for instance) which are quite scarce and very collectable.
OK now to your question...IAW Greenberg's Early American Toy Trains reference, the passenger coaches you show seem to be No 405 (no number appears on the car) from the period 1940's -1951. There is a variation in the circular logo that helps date them. Early cars say "HAFNER'S / STREAMLINERS/RAILWAYS" and then at some point production dropped the " 'S" and it became "HAFNER/STREAMLINERS/RAILWAYS" . The reference maintains that the logo with out the apostrophe is the later cars.
Great finds. thanks for posting
Don
