Well I don’t know about any changes made to the picture, but this is a cool train trip.
The Tren a las Nubes (English: Train to the Clouds) is a tourist train service in Salta Province, Argentina.
The service runs along the eastern part of the Salta–Antofagasta railway line of the Belgrano Railway (also known as the “C-14” line) that connects the Argentine Northwest with the Chilean border in the Andes mountain range, over 4,220 metres (13,850 ft) above mean sea level,[3] the fifth highest railway in the world.
The line got its name in the early 1960s after students filmed a trip on the Salta-Angofasta 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.
