The Great Western Railway is a short line railroad that operates between Greeley, Loveland, Longmont, and Fort Collins, Colorado. The original purpose of the road was primarily to get sugar beets to the sugar factories in Loveland, Longmont, and Greeley. During the road’s peak, passenger service was offered and some of the passenger cars can be seen at the Colorado Railroad Museum.
The Town of Windsor has a small museum in their park. These photos show the museum and some of the action in Windsor and Fort Collins (February, 2011).
