Looked into this a bit more and found out that this train is from a strange Bolivian train cemetary...and it's located on the largest salt flats in the world (100km x 120 km).
Butch: Sheesh, all Bolivia can't look like this.
Sundance: How do you know? This might be the garden spot of the whole country! People may travel hundreds of miles just to get to this spot where we're standing now. This might be the Atlantic City, New Jersey of all Bolivia for all you know...
Butch: You'll feel a lot better after you've robbed a couple of banks.
The real story?
