See the colorful diesels of the Ferrocarill de Antofagasta e Bolivia hauling their heavy loads over totally barren Cumbre Pass, across the Atacama Desert and in to the Andes at the Bolivian Border. Next, we see elderly EMD's of the Ferronor Diego de Almagro Sector struggling up the 3.5% grade to the smelter at Potrerillos. This line was washed out after
our visit and is now closed. The Ferronor Vallenor sector uses brand new EMD GT46AC's in a 24 hours a day service carrying iron ore from a mine to the port at Huasco. We also
see the now abandoned narrow gauge Ferrocarrill Tocapilla, which used Chilean built electric locomotives to carry nitrates from the Atacama Desert mines to the port at Tocapilla.
