High up in the altiplano plateau, within the Salar de Uyuni, there is a train graveyard.  Rather than methodically removing  locomotives and wagons, the local rail service instead runs them off the end of the line and leave them to rot in the salty desert.

The first time I visited this place, there was a simple yet eerie sense of otherworldliness.  However, upon my return, all the trains had been graffitied and the whole area had become a huge rubbish dump, which was a real shame.
