Spent many many hours with this shay......
I have the Lionel version.
Many miles on this.....
And own a set of Williams Superliners and locos to make my own Southwest Chief.
Rode these well into the Amtrak era.....so I bought Weaver units
And after a trip behind 765 on the Horseshoe curve.....
You get the idea......many others...611, 1218 Amtrak Cardinal....etc
