text: The Fire Precautions (Sub-surface Railway Stations) Regulations 1989 were introduced. Smoking was banned in all London Underground stations, including on the escalators, on 23 November, five days after the fire. Wooden escalators were gradually replaced, some remaining into the early 2000s (those at Wanstead were replaced in 2003 and at Marylebone in 2004,) and since 2014 the entire London Underground has been operating on metal escalators, after the last wooden escalator at Greenford on the Central line was decommissioned on 11 March 2014.
  By 1997, the majority of the recommendations of the Fennell report had been implemented, with safety improvements including the removal of any hazardous materials, CCTV fitted in stations, installation of fire alarms and sensors and the issuing of personal radios to staff.
  London Underground was also recommended by the Fennell Report to investigate "passenger flow and congestion in stations and take remedial action". Consequently, parliamentary bills were tabled to permit London Underground to improve and expand the busiest and most congested stations, such as London Bridge, Tottenham Court Road, Holborn and King's Cross St Pancras.
  Since then, major tube stations have been upgraded and expanded to increase capacity and improve safety. London Bridge was upgraded in conjunction with the Jubilee Line Extension project, which opened in 1999, King's Cross St Pancras was substantially upgraded and expanded as a component of the High Speed 1 project in the late 2000s, and Tottenham Court Road was expanded as part of the Crossrail project in the mid-2010s.
  The fire also led to improvement in firefighters' equipment: yellow plastic leggings that melted in the heat and rubber gloves that limited movement were replaced with more effective clothing.
