I stumbled on this video looking at other train videos.
If you're interested in 60's freight jump to 14:35. It doesn't just show the cars but how they worked and how they were used. There's also some relevant stuff to threads here like how popular 50' RBLs were (20:35), DF loaders and their operation (20:57) and that thinking 60' box cars were built for auto parts isn't just for foamers (20:51).
I also learned that UP had box cars with roof hatches which I'm thinking now is more common than I thought and I had never heard about the special flats for the Minuteman Missiles.
