Train Cemetery, Uyuni, Bolivia

There is little agriculture in the area because water supplies are scarce and somewhat saline. Today the town's primary function is as a gateway for tourists visiting the world's largest salt flats - the Salar de Uyuni. Each year Uyuni receives approximately 60,000 visitors from around the globe.
Transport
It is an important transport hub, being the location of a major railway junction. Four lines join there, respectively from La Paz (via Oruro), Calama (in Chile), Potosí, and Villazón (on the Argentine border, where the line now ends).
