replaced. British Rail, at the time carrying out an upgrade of the Tonbridge to Hastings Line which included the renewal of Grove Junction, decided that the cost of keeping the line from Eridge to Grove Jn open and undertaking the works, some £175,000, did not justify the outlay. It, therefore, announced the proposed closure of the line (including Groombridge and Tunbridge Wells West station) from 16 May 1983 which was later deferred after public objections. The Secretary of State for Transport agreed to the withdrawal of passenger services which took effect from 6 July 1985, although the section between Tunbridge Wells West and Birchden Jn remained open for rolling stock movements until 10 August, when the depot at Tunbridge Wells West station was shut. At the time of closure Tunbridge Wells West station had gas lighting, which was in operation in the ticket office and under the canopy. Preservation Restoration The Spa Valley Railway (SVR) has its origins in a charitable society formed on 13 September 1985, to purchase and reopen the Tunbridge Wells West to Eridge line. Named the Tunbridge Wells and Eridge Railway Preservation Society (TWERPS), it began a long struggle to reopen the line. The campaign received a setback in the late 1980s when Tunbridge Wells Borough Council gave planning permission for the construction of a large Sainsbury's supermarket complex on the site of the derelict goods yard of . While the 1891 locomotive shed and station building were protected as listed buildings, the remaining area of the site was obliterated, including the goods shed and signal boxes. However, planning permission was subject to the condition that the developer pay for construction of a new station platform and restoration of the engine shed. The North Downs Steam Railway relocated from Dartford in 1996, where it was experiencing vandalism problems, and merged with TWERPS. It transferred its assets and helped establish a base in the former LB&SCR locomotive shed. Also in 1996, the group acquired the line as far as Birchden Junction. Alongside the loco shed a new platform was built, from where services began running to Cold Bath Bridge (about away) in December 1996. Services were extended to Groombridge in August 1997 and to Birchden Junction in 2005. In 2007, SVR marked the 10th anniversary of the opening of the line by transforming Groombridge into a busy interchange station, with trains arriving or departing every 15 minutes.
