Paul: Wow. You are serious about this. Couple comments. 1. Your BTU figure for "western coal" is actually "Powder River Basin coal," which was used only by Northern Pacific. It's a common mistake these days to confuse one for the other, I know, but it makes me cringe. Try 11,000 BTU and you'll be in the ballpark for the Hanna, Rock Springs, or Kemmerer coal used by UP. 2. I deeply doubt the average freight train ran up Sherman Hill at 40 mph! Try 15-25 mph. Railroads generate cash by generating maximum GTM's at minimum expense, and high speeds uphill are about the biggest blunder they can make. If you go back and look at Kindig's and Perry's notes on their photos, they give speeds in the 15-25 mph range uphill. And if you poke around in the Ehrenberger/Gschwind and Kratville books, you'll find more evidence pointing unerringly to slow speeds uphill. Not fast. OS
