There used to be an operating steam engine over in East Texas that belonged to the state of Texas. They ran it during the summer and on weekends for tourists. I have no idea if it is still in operation.
Up in northern New Mexico, we have a narrow gauge railroad, the Cumbres and Toltec, that hauls tourists between Chama, NM, and Antonito, Colorado. And, of course, there is the narrow gauge railroad up in southwestern Colorado that runs between Durango and Silverton.
I have taken a ride on all of these at one time or another. The Cumbres and Toltec is my favorite, especially in the fall when the colors are at their best. YMMV.
