at King's Cross Metropolitan. In the 1980s the City Widened Lines were electrified and the Snow Hill tunnel reopened to passenger traffic as part of the Thameslink programme. The station was renamed, first to King's Cross Midland City and then to its final name, King's Cross Thameslink. Service on the line grew and new destinations were added, and by the 2000s the station could no longer handle the passenger numbers. A new pair of platforms were built at St Pancras, and King's Cross Thameslink closed in 2007. The station was included in the London station group from the group's inception in 1983, and remained so until its closure. Naming The station was officially known as King's Cross Metropolitan when it opened by the Metropolitan Railway in 1863, although on timetables and maps it was often just called King's Cross or King's Cross (Met.). The Metropolitan line part of the station was renamed to King's Cross & St Pancras in 1925 and then to King's Cross St Pancras in 1933, when the Metropolitan Railway was merged with the Underground Electric Railways Company of London to form the London Passenger Transport Board (LPTB). The station was then part of the King's Cross St Pancras tube station complex. The City Widened Lines platforms continued to be signed as King's Cross through to the 1970s. When the station reopened in 1983, following electrification, it was known as King's Cross Midland City and acquired its final name, King's Cross Thameslink, in 1988. Location and layout King's Cross Thameslink is located in a cutting around east of King's Cross mainline station. The station's main entrance was on the north side of the station at the western end of Pentonville Road, part of the London Inner Ring Road. This replaced an earlier entrance located south of the tracks on Gray's Inn Road. The Thameslink platforms were linked directly by stairs and a tunnel to the Victoria and Piccadilly line platforms at King's Cross St Pancras, and via both sets of platforms to the Circle, Hammersmith & City, Metropolitan and Northern lines as well as the mainline stations at King's Cross and St Pancras. The station had four platforms. The two to the south were for the Metropolitan line, and were used from 1863 to 1940. The two northern platforms, used from 1863 to 1979 and from 1983 to 2007, served the City Widened Lines and later the
