This former part of the L&N line from Memphis to Memphis Junction, KY, on the Louisville to Nashville main was abandoned around 1985. A section from McKenzie to Henry is abandoned, then from Paris through Springville, Big Sandy, Faxon, Bass Bay, Danville, McKinnon, Stewart, Tennessee Ridge (with an abandoned spur to Carlisle and Bear Spring), Erin, Dolomite, Cumberland City, Sailors Rest, Carbondale, Palmyra, Hematite (where a branch left to the south and ultimately Pond), Steelers and into Zinc.
The following site contains fascinating information on the relocation of this line when Kentucky Lake was formed on the Tennessee River. It also contains pictures of the most recent abandonment (the sections around Kentucky Lake have actually been abandoned twice!). A portion of the Houston County Railroad Bridge remains in place in Kentucky Lake.
