Sherman Hill across the Great Divide is the highest point on the Transcontinental Railroad, 8,247 ft. It's between Cheyenne and Laramie. I went over Sherman Hill on US 30 in the summer of 2019, but I think I have to go back to study this place. This hill is what forced the Union Pacific to build the mighty locomotives, the Challenger and Big Boy of the 1940s. Colorado may talk of their "fourteeners" (mountains over 14.000 feet), but for railroad, Sherman Hill is the ultimate.

Here's one video, of the UP 3985 Challenger on Sherman Hill:

Here's the UP 4014 Big Boy on Sherman Hill in 2015 - but it's being towed:

But for me, the ultimate was this, when the Big Boy AND UP 844 went over Sherman Hill under their own power in 2019:

It just doesn't get better than this.
