Son2 heard that Union Pacific steam locomotive #844 was heading up to Cheyenne for a "rest" and would be passing by on the tracks near Berthoud CO. So he took his camera up there and got a pretty good short video of the old loco going by. That got me excited about 844 again, possibly the most famous loco in the U.S. besides Big Boy.
I can't post his vid, but here's a real good one taken from a car paralleling the tracks. Long, and non-aficionados won't watch the whole thing, but we addicts will watch through it completely and wish for more.
Pretty good shot of the Stephenson reversing linkage at 7:30-ish. It's the bar with a slot in it rocking back and forth.
https://youtu.be/HRTYNxtbnjII got interested in the beast when they parked it next to my building in Denver on some side tracks* of Union Station. They had a ramp leading up to the cab so you could look around in it and talk to the engineer.
In hanging around it, the most common comment from the onlookers was how huge the drive wheels were.
(That's not me. Pic credit in Properties.)
I still regret not buying some souvenirs from the souvenir car behind the tender. There are costs to being a world-class cheapskate.
