On the CSX Main Line Sub that runs from Louisville to nashville,I can think of three golf courses along the tracks.There may be even more. The first is a country club across a roadway from the main line,I think it’s even named after the L&N. It’s at milepost 10 on the railroad. The next course is actually next to the tracks,in Coral Ridge,KY,just down the road at milepost 12. I also saw a small course down in Rowletts,KY, 70 something miles out of Louisville.
