CSX operates four north–south mainlines within its 20,000-mile network, providing critical links between the eastern seaboard, the Midwest, Appalachia, and the Southeast. These routes keep supply chains moving reliably, including the important Cincinnati-to-Atlanta corridor.
This 421-mile former L&N mainline is now part of the CSX Atlanta Division, running from northern Kentucky to northern Georgia, through rugged terrain with challenging grades and numerous tunnels. Split into 3 subdivisions – the CC, KD, and Etowah – it ties into the Georgia-owned Western & Atlantic mainline at Cartersville, which continues south by approximately 50 miles to downtown Atlanta.
In this video series, we’ll focus on the KD and Etowah Subdivisions, which make up 249 miles of this scenic route. As such, we begin our overview of the Cincinnati to Atlanta mainline in Corbin, Kentucky – home to an important railroad yard where coal trains are sorted and manifests are parked for crew changes.
Part one focuses on the KD between Corbin, Kentucky, and Dossett, Tennessee.
