Corrour railway station is on the West Highland Line, near Loch Ossian on the Corrour Estate, in the Highland Region (formerly Inverness-shire) of Scotland. It is the highest mainline railway station in the United Kingdom. It is located between Rannoch and Tulloch, and is sited from Craigendoran Junction, near Helensburgh. ScotRail manage the station and provide most services, along with Caledonian Sleeper. History Corrour station was built by the West Highland Railway between 1893 and 1894 on its line linking Glasgow with Fort William, and was operated from its opening on 7 August 1894 by the North British Railway. It has a passing loop around an island platform with a siding on the east side. In common with the line's two other remote passing places, Gorton and Glen Douglas, it was built with a tall signalbox and an adjacent low building in which the signalman lived. The adjacent low building (in Corrour's case) was also used as a sub post office from 15 December 1896 and a Post Office telegraph office from 16 August 1898; Corrour even qualified as a post town. Later, the railway constructed a station house for the signalman on the east side of the tracks, and the original building became purely office accommodation for the railway and the post office. Corrour was originally intended to be merely a passing place on the long section between Rannoch and Tulloch, called Luibruaridh (sic) after the nearest habitation, Luibruairidh, on the old drove road between Rannoch and Spean Bridge, about 1½ miles (2 km) northwest of the passing place. However, from its opening, its small island platform was used as a station, and the name Corrour was also used although Corrour Lodge at that time was where the drove road crossed Coire Odhar, some 5 miles (8 km) southeast of the station. However, when the station opened, estate traffic was facilitated by the building of a mile-long (1.5 km) track connecting the station to the old drove road as it passed near the head of Loch Ossian. In the early days, there was so much estate business that the railway employed an extra clerkess during the grouse season. It was theoretically a private station for the use of the estate, but it was also used by the public from the start, despite its not appearing in public timetables until September 1934. In 1897, the estate built a new lodge
