Empty train ascending the steep slope that begins at the station Montandon, and passing through the first tunnel. This train goes to Potrerillos Plant, where then loaded with sulfuric acid. Then, down the mountains again going to the Barquito Port (near Cha?aral). This picture has an anecdote for almost cost me my life ... I took pictures of the train up from the station, then when the train approached I crossed the tunnel ran but stumbled and fell in the middle of it, hitting me and spreading my things there. As I got up and ran (to save my life and take this photo) ... I barely make it. Trains to climb fast and full throttle ...
