The roundhouse, built in 1907, is home to 15 locomotives, 31 passenger cars, 25 freight cars and nine cabooses. Some of the locomotives and passenger cars are in use on the Osceola & St. Croix Valley Railway, a tourist line in Wisconsin.
Unfortunately, it was closed the day I was there—it's only open two days a week. Although the roundhouse was closed, I was able to wander around on the outside. See photos below.
