The Cumberland Valley Subdivision ( CV Subdivision) is a railroad line owned and operated by the CSX Railroad (CSX Transportation) in the U.S. states of Kentucky and Virginia. The line runs from Corbin, Kentucky, east to Big Stone Gap, Virginia,[3] along a former Louisville and Nashville Railroad line.
At its west end, the CC Subdivision heads north to Cincinnati, Ohio, and the KD Subdivision heads south to Etowah, Tennessee. The east end is at an interchange with the Norfolk Southern Railway Appalachia District, where CSX trains can proceed south to the Kingsport Subdivision at Frisco, Tennessee, via trackage rights.[4][5]
History
1886-1910: Construction of the original main to Norton
In 1886, the Louisville and Nashville Railroad (L&N) began to work toward a route into the Eastern Kentucky Coalfield. Work from Corbin, Kentucky commenced on April 29, reaching the town of Pineville, Kentucky in 1888.[6] The following year, the line was completed to Middlesboro, Kentucky. The line would reach into Southwest Virginia through a tunnel under the Cumberland Gap on September 1, 1889. The route was extended up the Poor Valley to Big Stone Gap, Virginia on April 15, 1891, then to a place called Intermont, Virginia (now Appalachia) where it connected with the Atlantic and Ohio (later Southern Railway). The route was completed to Norton, Virginia (then Prince's Flat) on May 15, 1891, completing a connection with the Norfolk and Western Railway (N&W).[7][1]
Middlesboro Belt Line
Paralleling development of the L&N in Bell County was the building of a rail network in and around the town of Middlesboro, Kentucky. In 1886, the Middlesborough Belt Rail Road (MBRR) was constructed, encircling the town and running up Bennett's Fork to the southwest. The L&N would purchase the shortline on November 4, 1896.[8]
1910-1930: Into Harlan County
The present CV main from Pineville into Harlan County, Kentucky began life in 1910 as the Wasioto and Black Mountain Railroad. Constructed by local businessman T.J. Asher, the line departed the CV mainline near Wasioto, Kentucky and ran up the Cumberland River to Tejay, Kentucky.[7] Shortly after its construction, the L&N would purchase Asher's railroad and extend it further up the river valley, arriving at Harlan, Kentucky in 1911. The L&N would follow up its Harlan County arrival with branches up the three forks of the river: Poor, Clover, and Martin. The L&N's Harlan County service would be enhanced in 1921 with the construction of a 17-track yard at Loyall, Kentucky.[6]
1930-1986: Expansion and the Switchback
Further progress was made in 1930, when L&N completed what was then the Martin's Fork Branch and constructed a 6,244-foot tunnel under the Cumberland Mountain at Hagan, Virginia. Original plans called for an extension to connect with the Carolina, Clinchfield, and Ohio Railway (better known as the Clinchfield Railroad). However, plans were scrapped due to financial uncertainty, and the L&N decided instead to connect the new tunnel to the existing Middlesboro–Norton mainline via a switchback.[1] To compensate for the lack of a connection to the Clinchfield, the L&N would obtain trackage rights over the Interstate from Norton to reach the railroad.
By 1939, there were at least eight separate branches constructed in Bell County, including one at Fourmile; one up Straight Creek from Pineville; one that ran up Clear Creek to Chenoa; a branch up Puckett Creek at Blackmont; and another up Bennett's Fork in Middlesboro.[9]
The L&N would replace the double-tracked portion of the line between Corbin and Harlan Junction with centralized traffic control (CTC) in 1956.
1986-present: Big Stone Gap Connection to present
In early 1986, now-owner CSX Transportation constructed a new bridge and a connection to the Norfolk Southern Railway (ex-Southern Railway) at Big Stone Gap, Virginia, utilizing that railroad's Appalachian District as a new route to the Clinchfield main. The original route to Norton would eventually be abandoned.[6]
