High Quality Content by WIKIPEDIA articles! The Yellow Train line (French: Train Jaune, Catalan: Tren Groc) is a railway that runs from Villefranche-de-Conflent through to Mont-Louis in France. It was started in 1903 and the section to Mont-Louis was completed in 1910, followed by an extension to Latour-de-Carol in 1927. It is 63 km long and climbs to 1593 m at Bolquère-Eyne, which is the highest railway station in France. There are 19 tunnels and two bridges, one of them a suspension bridge which is very unusual for a railway. The trains are powered by electricity at 850 volts DC, collected via a third rail. The power comes from hydro-electric generators on the River Têt. There are open and closed cars. The open cars are a favourite with tourists and dramatic views are possible as the train climbs along the twisting track. The maximum speed of the train is 55 kilometres per hour.
