The Dayton District is a railroad line owned and operated by the Norfolk Southern Railway in the U.S. state of Ohio. The line runs from Columbus southwest to Cincinnati along former Pennsylvania Railroad and New York Central Railroad lines. Its east end is at or near the Columbus District, Sandusky District, and West Virginia Secondary; its south end is in Ivorydale, where it meets the Indiana and Ohio Railway's Midland Subdivision, and just past that in Winton Place, where it meets CSX Transportation's Cincinnati Terminal Subdivision. Along the way, it junctions the New Castle District at Evendale.Trackside Guide No. 1: Cincinnati, Trains, September 2002
