- I understand opinions vary on when the steam era ended. I think <=1956 isThat's probably about right; some steam survived later, but not much.
However, I'm inclined toward ca. 1960 as a cutoff because, give or take a
year or two, that was the beginning of what I regard as the modern era:
roller bearings, cushion underframes, mechanical reefers, etc. Prior to
1960, only a few more or less experimental cars had those features, and
freight car technology wasn't much different than in 1950.
