The train cemetery is just outside Uyuni, Bolivia, near the world's largest salt flat.

A booming mining industry attracted the British, who built a railway though here in the late 19th century.

In the 1940s, the industry declined.

Steam trains were abandoned outside the city and left to rust.

After decades in the wind, near a massive collection of salt, they're rusted out.

Covered in graffiti, the trains take on a strange beauty.

The site has become a minor attraction.

Tourists in the region stop here before visiting the nearby salt flat.

The trains now double as an industrial playground.

Now, the country has attracted foreign attention again, thanks to its enormous deposits of lithium, used to make batteries for smartphones and electric cars.
