This place is called the train graveyard in Bolivia's Uyuni region. At this site, located near the Salar de Uyuni, a popular tourist attraction, trains that once carried minerals mined near the salt lake have been dumped. The abandoned train was later converted into playground equipment, and now visitors can climb on it and play freely.
