I lived in Colorado for over 30 years. I've been to Silverton; I've been to Durango BUT I have never taken that train ride - Now I live in Florida. Big change.
Just to share a personal anecdote regarding steam trains.
I was in a hospital in Strasbourg, Alsace, France, to have my tonsil taken out at the tender age of four (c. 1950). My bed was next to the window in the ward. I stood up and was able to watch a steam train pulling many wagons across the horizon from one side to the other. I have been hooked since.
