Despite its modest site and geographical isolation, Uyuni is worth an hour or so walking around. Particularly the Avenida Ferroviaria has many monuments, mostly railroad related.
Allegedly Bolivia's first locomotive, stands in the emiddle of Avenida Ferroviario, by the corner of Calle Santa Cruz. The first locomotive is in Pulacayo almost 20 kilometers on the road to Potosi. Used in the Huanchaco mine.
Train Graveyard
a couple of km south of town, by the railway to Chile, there are dozens of old, rusted locomotives, a few wagons and some other antiquated machinery. Usually a stop on salt flat trips.
