Mammoth Cave Railroad ("Dinkey Train") was a short rail line with a small train off the Louisville and Nashville Railroad (L&N) that went to Mammoth Caves in Kentucky. The tiny 9-mile (14 km) railroad from Glasgow Junction (Park City) to Mammoth Caves was started in 1886 and operated for 45 years. The complete Dinkey Train consisted only of a "dummy" 0-4-2T type steam locomotive and a wooden coach to carry passengers and their luggage. Among the many stops on the way to Mammoth Caves were Diamond Caverns, Grand Avenue Cave, Procter Cave and Hotel, Chaumont Post Office, Union City, Sloan's Crossing, and Ganter's Hotel. The Dinkey Train could obtain speeds of 25–35 miles per hour on the lightweight rails.
