This is the backside of the mountain side above Reshui. The railroad climbs the pass using two big loops, so that three levels of track are visible from Reshui. In going from the second to the third level the railroad tunnels through the ridge so that a short stretch of the third level is on the backside of the ridge, before ducking into another tunnel and reappearing above Reshui. This is the view if you hiked over the ridge in the early morning. This was one of the few single engine trains I saw since most trains were doubleheaded.
