The Clinchfield Railroad was an operating and holding company for the Carolina, Clinchfield and Ohio Railway . The line ran from the coalfields of Virginia and Elkhorn City, Kentucky, to the textile mills of South Carolina. The 35-mile segment from Dante, Virginia, to Elkhorn City, opening up the coal lands north of Sandy Ridge Mountains and forming a connection with the Chesapeake and Ohio Railway at Elkhorn City, was completed in 1915. The Clinchfield was the last Class I railroad built in the U.S. east of the Rocky Mountains. The 266-mile railroad provided access to numerous scenic wonders of the Appalachian region and is probably best known for the state-of-the-art railroad engineering techniques applied in its construction, as exemplified by the Clinchfield Loops climbing the Blue Ridge Mountains north of Marion, North Carolina. The Clinchfield Railroad began operating the line December 1, 1924, and for many years it was leased jointly by the Atlantic Coast Line Railroad and Louisville and Nashville Railroad. When the L&N merged with the ACL's successor, the Seaboard Coast Line Railroad, effective January 1, 1983, forming the Seaboard System Railroad, the separate operating company was unnecessary and was merged into the Seaboard. The line is now owned and operated by CSX Transportation as their Blue Ridge Subdivision (Spartanburg to Erwin, Tennessee) and Kingsport Subdivision (Erwin to Elkhorn City). At the end of 1925 the railroad operated 309 miles of road and 467 miles of track; mileages in 1970 were 312 and 501. History The conceptual beginnings of the Clinchfield Railroad predates the railroad era, leading back to the period of westward movement after the Revolutionary War where turnpikes and other ground transportation routes were considered. Discussions related to a transportation route from the Ohio river to the South Atlantic was during a convention held at Estillville, Virginia in 1831. The Estill plan closely resembles the route followed by much of the Clinchfield construction. The Charleston, Cincinnati and Chicago Railroad (1886-1893) In 1886 ex-Union Gen. John T. Wilder received a charter for the Charleston, Cincinnati and Chicago Railroad, commonly referred to as the "Triple C" Railroad. This was the beginning of the modern Clinchfield. The promoters proposed a 625-mile line from Ironton, Ohio, to Charleston, South Carolina, with an extension down the Ohio River to Cincinnati. It would serve the rich agricultural lands of the Piedmont, the summer resorts of the North Carolina mountains, the rich timber
