An empty autorack train led by one of Norfolk Southern's unique standard cab Dash-9s attacks the hill at Blair on the Oakdale (or K&O) Line. This mainline, which serves as a connection between the A-Line in Knoxville and the CNO&TP in Harriman, is not heavily used, but still sports 5-6 through trains each day. The old Southern-style signals still stand on most of the route, but likely won't be around much longer as PTC slowly encroaches.
