North American Rayon Company, 1936 H.K. Porter Company, 0-6-0F Fireless Locomotive, Elizabethton, Tennessee. The locomotive was called "The Pot". This rare fireless locomotive was built in 1936 for the North American Rayon Company (N.A.R.C.) of Elizabethton. Its steam was supplied from a large reservoir located inside of the N.A.R.C. plant. Fireless locomotives were used in industrial situations where there was an increased risk of fire. N.A.R.C. made Rayon, which is a highly flammable material. The locomotive retired from service in 1992 and it is possibly the last fireless locomotive to be retired from service in the United States. N.A.R.C. shutdown in 2000 and donated "The Pot" to the Carter County Chamber of Commerce and is on public display in Elizabethton, Tennessee.
