Note: Though periodically updated, the red and blue polylines on this Google map may not be in perfect sync with the train track or river paths, due to the continual updating by Google of their aerial projections/algorithms, as well as natural water flow course-direction changes.
Note: Notice the twelve tunnels leading up to the Potrerillos copper smelting plant. Note: The rail line (the red polyline) follows the same approximate route to the Port of Chañaral from the city of Diego de Almagro as does the Salt River route (the blue polyline)—and therefore is represented from Diego de Almagro to the Port of Chañaral by the blue polyline.
This Google Map web page is “mobile-friendly” down to a “320x480-pixels” screen-size. But, due to the nature of maps, the larger the screen this web page is viewed on, the better. Browsers that are not “matchMedia” capable (such as Internet Explorer 9) will not receive automatic “zoom-level” adjustments at smaller screen sizes to optimize the map’s appearance.
