Tren a las Nubes: Riding Argentina's Train to the Clouds

The Tren a las Nubes, meaning "Train to the Clouds," is an iconic Argentinian railway that offers a thrilling journey through the Andes Mountains. The train's route is a marvel of engineering, featuring 29 bridges, 21 tunnels, 13 viaducts, and two zig-zags. The railway was originally constructed to connect northern Argentina with Chile, facilitating the transport of goods from the Chilean coast. Construction began in 1921, and the complete railway was inaugurated in 1948. The route was designed by American engineer Richard Maury. The train ascends to a staggering 4,220 meters (13,842 feet) above sea level, making it one of the highest railways in the world. The train's name was inspired by a documentary film that captured the vapor plumes created by the train's steam mixing with the cold mountain air. The highlight of the journey is the famous Polvorilla Viaduct, a massive structure 63 meters above the ground. Today, the Tren a las Nubes is primarily a tourist attraction, offering visitors a chance to experience the breathtaking landscapes and engineering marvels of the Andes. The service offers a round trip, combining bus and train travel. The bus departs from Salta and drives to San Antonio de los Cobres, where passengers board the train to the Polvorilla Viaduct. During the journey, passengers can enjoy regional snacks and learn about the history and culture of the region from local guides. It is important to take precautions against altitude sickness, such as staying hydrated and avoiding strenuous activity.
