It's very possible that MP hoppers may have run over Sherman Hill on
the UP in the early 50's because Geneva Steel also used 20% Arkansas
Coal between 1956 and 1966. It's possible that it may have started
earlier.

Don't know if this helps the general history or not, but I have a photo of a
solitary loaded MoPac gondola headed west at Laramie (probably taken when I
should have been studying for vertebrate morphology or some such class) in
the 1970s. Remember the steam era never ended on the Union Pacific! :^)
