UP 4014 rounds the bend from Tie Siding on Main 1, leading into the cut on the west side of Hermosa Tunnel. For whatever reason, UP typically runs trains on the left train between Tie Siding at Cheyenne. The tracks are, of course, CTC. So the dispatcher can run trains either direction on either main at his or her discretion. However, that discretion is generally the lefthand main.
