Carstairs railway station serves the village of Carstairs in South Lanarkshire, Scotland and is a major junction station on the West Coast Main Line (WCML), situated close to the point at which the lines from London Euston and Edinburgh to Glasgow Central merge. Constructed originally by the Caledonian Railway, the station is operated today by ScotRail and is also served by one TransPennine Express trains service per day between Manchester Airport and Glasgow Central. All other services by TransPennine Express and services operated by Avanti West Coast, Caledonian Sleeper, CrossCountry and London North Eastern Railway pass the station, but do not stop. History Construction work started on the site on 30 August 1845 and the station was opened by the Caledonian Railway on 15 February 1848 when the line between Glasgow and Beattock opened. The line from Edinburgh reached Carstairs and opened on 1 April 1848. By 1855 traffic had increased substantially, and the Caledonian Railway spent around £15,000 () at Carstairs increasing capacity to allow incoming trains from Glasgow, Edinburgh and the north to be arranged for their journey south. In 1885 a correspondent known as Trans-Clyde to the Glasgow Herald reported on the poor state of the platforms at Carstairs:In the interest of the travelling public whose number is legion, allow me to bring to notice the most urgent and pressing necessity which exists for the directors of the Caledonian Railway taking immediate measures to put the platform at Carstairs Junction into such a condition as shall answer efficiently all the purposes of a railway platform intended for the use of travellers…If your or any of your readers have been to Carstairs Railway Station, on the opening of the doors of the railway carriage they must have seen that the stone platform on which they are required to alight for the purpose of changing carriages (the main or almost sole object of this station) is several feet below the level of the carriage which they occupy-how many feet in each case I cannot say, as it may vary but lately I took occasion to measure the distance between the platform and the floor of a carriage from which I had managed to descend, and found it to be 3 feet 4 inches at least. From 1888 to 1895 the station was also the terminus of the Carstairs House Tramway which connected to Carstairs House. Between 1914 and 1916
