Headcorn station was opened on 31 August 1842 as part of the extension of the South Eastern Railway's main line from Tonbridge. In common with other SER stations outside the London area, staggered platforms and a simple single-storey wooden clapboardstation building were provided at Headcorn. The SER's line was opened to Ashford by December 1842, to Folkestone by December 1843 and finally to Dover by February 1844. A bridge between Headcorn and Staplehurst was the scene of an accident in 1865 involving Charles Dickens; a rail had been removed by a ganger mistaken as to the day, and the Staplehurst rail crash resulted. In 1905, the station became the northern terminus of Colonel Stephens' Kent and East Sussex Railway, the KESR's tracks entering Headcorn via a siding on the Ashford side of the station. The KESR had its own long platform to the rear of the Up main line platform, and a corrugated iron building was moved here from the KESR's Tenterden Town station. The station, known as Headcorn Junction by the KESR, was remodelled between 1924 and 1930 by the Southern Railway, with the addition of two new fast lines through the station. This involved the demolition of the main line Up platform, its reconstruction opposite the Down platform, and the moving of the KESR's connection to the main line to the west side of the station. A new concrete KESR platform was provided here facing on a curved alignment. The remodelling included a footbridge across the station and new signal box for the main line and an SR signal for the KESR branch. A connection was also provided between KESR metals and the SR Up loop line on the London side of Headcorn station, the KESR's facilities consisting by now of two loops and a siding. Following a decline in passenger and freight traffic, the KESR between Headcorn and Tenterden was closed to all traffic in 1954. Goods facilities were withdrawn from Headcorn in 1962, and the goods yard became a car park. The SER's original buildings however survived until 1988 when they were swept away by British Rail as part of a modernisation scheme. A new red-brick station building was officially opened on 11 May 1989 by Ann Widdecombe, then Maidstone's MP; shelters were provided for the platforms. In 1994, a new freight loop was built for Channel Tunnel Freight services.
