In Potrerillos, near Diego de Almagro town in northern Chile, the sun has been hidden between the hills of the Andes mountain, the night will begin soon and trains of FERRONOR railway continue working, out of the tunnel No.7 and downward from Potrerillos foundry by the hard line to Montandon, and then continue to Barquito harbour in Cha?aral.
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.
