Solar-Powered Tourist Train Operates in Jujuy’s Quebrada de Humahuaca, Argentina

Argentina’s Jujuy Province has launched the continent’s first solar‑powered tourist train, the Tren Solar de la Quebrada, which travels through the UNESCO World Heritage Quebrada de Humahuaca. The service links five towns—Volcán, Tumbaya, Purmamarca, Maimará and Tilcara—using lithium‑ion batteries recharged by solar panels at strategic stations, eliminating diesel engines and cutting emissions, noise, and fuel costs.

The initiative is promoted as a model of sustainable tourism, offering visitors scenic views of the multicolored hills, historic streets and local markets while showcasing renewable‑energy technology in a real‑world transport setting.
