Tren a las Nubes gives you the unique opportunity to travel among clouds. Amongst the highest railways, Tren a las Nubes in Argentina allows you to explore a breathtaking journey of about 271 miles covered in approximately 15 hours. Originally begun for commercial and economic reasons it now is an unusual tourist attraction drawing in thousands of visitors every year. The average height of the tracks being quite high you could view clouds all around and below. This train is thus often referred to as ‘train to the clouds’.
The historic train of the clouds journey in South America operates between Salta and La Polvorilla viaduct near Chile border. As you traverse this route you would come across 21 tunnels, 29 bridges, 13 viaducts, 2 zigzags, and 2 spirals. The zigzags are particularly intriguing with the train having to move parallel to mountain slopes while making a climb.
The route conceived by Richard Fontaine Maury, a US Engineer, was for the purpose of connecting the borax mines of the interiors to the main commercial centers. Construction of this project started in 1921, with the highest point La Polvorilla viaduct at 4220 meters being finished in 1932. Though inaugurated in 1948 it started its heritage journey in the 1970s. The route from Salta to La Polvorills gradually increases in height which is very inspiring. In between, there are nineteen stations some of which are Cemillos, Campo Quijano, V. Toledo, Ingeniero Maury, Puerta de Tastil, Meseta, Diego de Almagro, Cachinal, and Mina Concordia.
This train of 10 wagons running on the meter gauge track is hauled by 2475 hp diesel-electric locomotive.
