Thanks for the video. I had some understanding on how they work. I have helped operate a farm steam tractor. But, I am over joyed we don't have such complexity in our fun machines.
Due "popular applause" how'd ya like it if your "workbench" looked like this . . . . Union Pacific (Big Boy) Steam Shop Tour (ps: In the 1st vid is it true? They say, early on, it would take "4 modern engines" (ie: diesel electrics?) to do the work that one Big Boy could do?)
There was one at the Ashwaubenon (Green Bay) museum. It took a long time to walk around it and the tender. We could even clime into the cab. WOW!!
Thanks for posting that great video! Of course, "...4 modern engines..." covers a wide spectrum of locomotives, Doug
