a&b) These slides, dated May 1968, are labeled "Incline RR". They are photographs of the Incline Railroad on Lookout Mountain. Due to the tourism and the railway boom, a new, broader incline railway opened in November 1895 to replace the one that had serviced a resort hotel atop Lookout Mountain in the 1880s. "The Incline" was built by John Crass and the Lookout Mountain Incline Railway Company. It is one of the steepest passenger railways in the world, reaching an incline of 72.7%. Since 1911, when the original coal burning steam engines were replaced by two 100 horsepower motors, the Incline has changed very little during over 100 years of operation and still remains a prominent Chattanooga tourist attraction.
