An N&W Y6b runs through the deep cut at the old Post Tunnel. Although this nighttime photograph looks like the work of O. Winstorn Link, this photo was actually taken by railfan Charley Butterworth, perched high above the track, likely on one of the piers of  Post trestle on the new line.  The fact that there is a Y6b running on the old line suggests this is leased N&W power running on the Bluefield before the 1950 buyout.

N&W Class A pulls a heavy freight on The Bluefield in January of 1951. She is seen running through the rock cut just past Post tunnel. This line only saw occasional service after 1944, when a grade reducing cutoff was built. The new line reconnected to the old line near Big Run.
