In the far north of Argentina, you can find the “Train to the Clouds”. This tourist train was opened in 1948 after two decades of work, and in 1972 it began being officially used by tourists as a heritage railway. After many pauses amid the economic crises that the country faced years ago, the train finally came back to life.
The train departs from Salta to San Antonio de Los Cobres, a small town that lives off the mining industry and is located at 3,775 meters above sea level.
Passing this town, the train reaches La Polvorilla viaduct, located at 4,200 meters above sea level, one of the most exciting points of the ride, when the train crosses this 64 meters high metal structure.
The engineering masterpiece of this railway line can be seen at departure and on the way back, consisting of 29 bridges, 21 tunnels, 13 viaducts, 2 spirals and 2 zigzags.
