History


Beginning

The possibility of a railway in the area began to be explored as early as 1889, and numerous studies were carried out up until 1916 analysing the feasibility of the line given the steep gradients and harsh terrain. Construction of the railway officially started in 1921, with the intention of connecting the North of Argentina with Chile across the Andes. The ''La Polvorilla'' viaduct, the highest of the line, was finished on 7 November 1932. The route was designed by American engineer Richard Maury, (who later died in Salta) and after whom one of the stations has been named. The complete railway was inaugurated on 20 February 1948, following numerous delays and complications and a two-year period where work was stopped. The line got its name in the early 1960s after students filmed a trip on the Salta-Antofagasta railway from inside the train carriages, often showing the vapor from the then-steam locomotive which – together with the cold mountain air – formed large vapour plumes. The footage was later offered to the '' Clarín'' newspaper to make a documentary, which was subsequently called ''Tren a las Nubes'' ("Train to the Clouds") because of the vapour clouds in the film. Ferrocarriles Argentinos (FA) later adopted the name to make it more appealing to tourists. It was not until 1972 that the route began being officially used by tourists as a

In 2005 a train stopped at a height, with passengers having to be evacuated using helicopters. Since then, the National and Provincial Governments rebuilt the line, replacing of tracks and granting a new concession to private company "Ecotren" to operate the Tren a las Nubes. The train was again opened to the public on 6 August 2008,


Renationalisation

In July 2014 a train derailed near Abra Muñano, at a height, . before reaching San Antonio de los Cobres. About 400 passengers had to be evacuated from the train. After the incident, the Government of Salta led by Juan Manuel Urtubey rescinded the contract with "Ecotren", alleging safety failures. Following these events, the service was re-nationalised and the Province took over the operation and maintenance of the service. through a recently created state-owned company, "Sociedad del Estado Tren a las Nubes SFTSE". With the Government of Salta as operator of the service, the Tren a las Nubes was announced to be running again by March 2015, although the service did not begin running again until 4 April 2015. During the 8-month closure of the line, both the National Government and the government of Salta had restored much of the
