It is a two-hour, narrated 20-mile round trip between Hill City and Keystone. Passengers view vistas of Harney Peak, mining encampments and participate in good old-fashioned fun. Trains follow the original route of the Chicago, Burlington and Quincy Railroad laid down in the late 1880s to service the mines and mills between Hill City and Keystone. The Black Hills Central Railroad is the oldest continuously operating tour railroad in the nation and operates three steam and two diesel engines throughout the season. One of our steam engines is close to 100 years old!
