Historical Background

Have you ever wondered how the Tren a las Nubes came to be? In the late 19th century, the idea for this magnificent railway emerged to connect Salta, Argentina, and Antofagasta, Chile, traversing the rugged Andes mountains.

Overcoming the harsh Andean environment took immense effort, and the railway wasn't completed until 25 years later, officially opening on February 20, 1948.

The railway's highest point, the La Polvorilla viaduct, stands at an impressive 4,220 meters (13,850 feet) above sea level, showcasing the engineering prowess of Ricardo Fontaine Maury.
