was refurbished with the aim of extending its service by a further ten years. The first two phases of the Southern Railway's electrification scheme were revived in 1955. This did not include the Hastings line and it was announced in 1956 that a fleet of diesel-electric trains would be constructed to operate the service until the line was electrified. At that time, the rolling stock built in the 1930s was overdue for replacement. The modernisation to the Hastings line and the introduction of the diesel-electric trains cost £797,000, of which £595,000 was the cost of the first seven trains. A further thirteen trains cost £1,178,840. Electrification was finally carried out in the 1980s, as detailed below. Operators From 1845, the line was operated by the SER. In 1899, the SER and LCDR entered into a joint working partnership, the South Eastern and Chatham Railway (SECR). On 1 January 1923, the Railways Act 1921 came into force, resulting in the Grouping. The SECR became part of the Southern Railway (SR). On 1 January 1948, the Transport Act 1947 came into force, and the SR became part of British Railways, with the former SR lines becoming the Southern Region.

On 1 January 1994, the Railways Act 1993 came into force, privatising British Rail. Passenger services were taken over by Connex South Eastern on 13 October 1996.

The Strategic Rail Authority took over the running of passenger trains from 9 November 2003, using their South Eastern Trains train operating company. On 1 April 2006, Southeastern took over the operation of passenger trains on the route. On 17 October 2021 SE Trains took over the operation of passenger trains on the route. Operation Steam era (1845–1957) From the opening of the line, passenger stock consisted of 4-wheel carriages. In 1845, there were eight passenger trains a day from Tunbridge Wells to London, with half that number on Sundays.
