Another Tatoo Train in Potrerillos wall: Spectacular trip between Potrerillos and Montandon metric gauge line, in Diego de Almagro city (North of Chile). Already ending the day, FERRONOR sulfuric acid train down from Potrerillos foundry and CODELCO copper plant, with a maximum slope of 3.9% in this section, confronting the abyss and the danger, and with its characteristic black color in GR12 locomotive, seems a tattoo on the wall of the mountain.
Landscape photography is difficult due to the challenge of combining good light and good scenery. Good railroad photography enters another level of complexity since it requires the first two while there is a train in view.
