• The most amazing train in the world, the one that takes you to the clouds, reaches a height of 4,200 meters in its 217 km trip.
  It is one of the highest railways in the world, taking its way across the high picks of the Cordillera de los Andes, surrounded by striking sceneries. The train departs from the city of Salta, passes through the Valle de Lerma, enters the Quebrada del Toro and finally reaches La Puna.It takes its name Tren a las Nubes, from the clouds that are often seen under bridges and around slopes.
  The number of spirals, viaducts, tunnels and other twists and turns that the train passes through arises from a decision made by the designer of this project, the US engineer Richard Maury. He took into account the principle of adhesion of train wheels to the railways and the laws of physics, ruling out the funicular system commonly used, so that the train may safely reach the expected heights. The train has no cogwheels, not even for the steepest slopes, since the railways are peculiarly arranged, running through a system of zigzags and spirals.
  The train leaves from the General Belgrano station in the city of Salta, 1187 meters above the sea level, and ends its journey at the viaduct.

THE ROUTE

It leaves from the train station at the city of Salta and ends its route at La Polvorilla Viaduct.
The railways reach a height of 4,200 meters above sea level, turning this train into one of the highest in the world.
The train offers meals onboard, translator services, and medical assistant for any passenger that may be affected by the lack of oxygen caused by the height. The trip lasts approximately fifteen hours, from seven am until midnight or later. The train runs 217 km. and passes through 29 bridges, 21 tunnels, 13 viaducts, 2 spirals, and 2 zigzags.
It leaves from the city of Salta, the lowest point, and from there it begins the upward route until it reaches the final point at La Polvorilla Viaduct, the highest in the trip. As you reach the different stations, local villagers at picturesque stands sell craftwork, clothes, and regional products as interesting souvenirs of the trip.
The train services include dining car, panoramic car, folklore shows, medical practice, audio, video, and bilingual guides.
