The station was rebuilt in the 1990s to try and rectify the station's overcrowding problem with a new tunnel excavated and platform for North bound trains. The original tunnel became an extra-wide platform for South bound services. Access to the platforms from the surface was originally via three lifts but during the rebuilding these were replaced by escalators, one of these being the longest on the London Underground and the fourth longest in Europe . The main escalator is sixty metres long and rises twenty-seven metres .
