I recently visited the Nevada Northern Railway Museum in Ely (eee lee), Nevada. A small admission fee allows you to wander the several workrooms of the repair shop and engine barn. Restoration is ongoing on engines, a caboose, and boxcars. Enough work to last decades. The four engines below are working trains. For a price, and by taking the required safety training, they are all available to drive. They even offer a “Railroad Reality Week” where you spend the entire time learning how to work on a railroad.
