A westbound BNSF manifest freight exits the west portal of Mullan Tunnel at Blossburg, Montana, on September 24, 2006. Since this time, the cut leading to this portal has been widened and lengthened during a extensive Tunnel rebuilding in 2009 that increased vertical and horizontal clearances inside the tunnel, as well as decreased its length from 3,879 to 3,496 feet long, moving this portal east about 400 feet.
