Chetoogeta Mountain Tunnel Georgia's oldest underground trainway, the 1,147-foot Western & Atlantic Railroad tunnel at Tunnel Hill in Whitfield County, was completed in 1849-50. Visitors can now walk inside thanks to its recent restoration and conversion to a tourist attraction. A few yards to the north is a newer, larger replacement tunnel built in 1928 by the Nashville, Chattanooga & St. Louis Railway, which leased the W&A from the state of Georgia in 1890. This tunnel, built at a cost of $290,000, was designed to handle the largest rail cars and locomotives then in use by American railroads. It is still in use by NCSL successor CSX Railroad.
