In 1989, a refurbishment programme was started across the whole fleet of London Underground rolling stock, following the King's Cross fire in 1987. The Victoria line stock was chosen to be the first to be refurbished (repaired, changed and made to look newer). The refurbishment was carried out by Tickford Rail at Rosyth Dockyard. The refurbishment was due to take 5 years to complete, but the last train did not leave the works until 1997, because each train was slightly different to the next train. When the trains had completed the refurbishment the outside was painted in a white, blue and red colour scheme. The insides of the trains have fire-resistant materials and are finished in the Victoria line blue colours, though some have the Bakerloo line brown as they run on that line too.
