If a guy is lucky enough to get a southbound move on the CV Sub leaving Loyall, KY, in the afternoon, the old L&N tower at Harlan Junction is a cool spot. A stone train out of Mount Vernon, KY, to Brice, NC, has a 15:00 outbound crew and helper on at Loyall. The train has just departed as the C702 crew brings up the rear end as they past the tower at Baxter. The helper crew will shove this loaded train from Loyall to Gates City, VA, 72 total miles. The CV Sub is a CSXT branchline that runs from Corbin, KY, to Pennington Gap, VA, which trains use to get down to Kingsport and the Clinchfield.
