===Station lifts and escalators===
Most original deep-level stations were installed with lifts and stairs, with some descending directly down to platform level.{{sfn|Wolmar|2005|p=188}} Many of these were given an overhaul in the 1930s with escalators replacing lifts for quicker passenger flow.{{sfn|Badsey-Ellis|2016|p=212}}{{sfn|Horne|2007|p=93}} Underground stations on the Cockfosters extension were built with access mainly via escalators; each station shaft are able to fit three escalators, but some stations had two escalators with a stairwell by the middle. Escalators at Bounds Green, Wood Green and Manor House travel at {{convert|165|ft|m}} per minute, which were then the quickest on the network.{{sfn|Horne|2007|p=82}} All of the original lifts were either replaced by new equipment or were converted to escalators. [[Alperton tube station|Alperton]] was the only above ground station to have an escalator, which was transferred over from the [[Festival of Britain]], but was decommissioned in 1988.{{sfn|Horne|2007|p=128}} Stations such as Green Park and King's Cross St Pancras were installed with new lifts to provide step-free access to every platform by the [[2012 Summer Olympics]].<ref name="upgrade2008">{{cite press release |url=https://tfl.gov.uk/info-for/media/press-releases/2008/august/green-park-tube-station-to-be-upgraded-ahead-of-london-2012-games |title=Green Park Tube station to be upgraded ahead of London 2012 Games |publisher=[[Transport for London]] |date=18 August 2008 |access-date=30 August 2020 |url-status=live |archive-date=30 August 2020 |archive-url=https://web.archive.org/web/20200830162224/https://tfl.gov.uk/info-for/media/press-releases/2008/august/green-park-tube-station-to-be-upgraded-ahead-of-london-2012-games }}</ref><ref name="upgrade2011">{{cite press release |url=https://tfl.gov.uk/info-for/media/press-releases/2011/september/transformation-of-green-park-station-nears-completion |title=Transformation of Green Park station nears completion |publisher=[[Transport for London]] |date=6 September 2011 |access-date=30 August 2020 |url-status=live |archive-date=30 August 2020 |archive-url=https://web.archive.org/web/20200830162224/https://tfl.gov.uk/info-for/media/press-releases/2008/august/green-park-tube-station-to-be-upgraded-ahead-of-london-2012-games}}</ref><ref>{{Cite magazine |last=Cole |first=Margo |date=22 April 2010 |title=Major Project – King's Cross Underground Ticket Halls |url=http://leewoodprojects.co.uk/wp-content/uploads/2010/07/kings-cross-st-pancras-nce1.pdf |archive-url=https://web.archive.org/web/20170102152229/http://leewoodprojects.co.uk/wp-content/uploads/2010/07/kings-cross-st-pancras-nce1.pdf |archive-date=2017-01-02 |url-status=live |magazine=New Civil Engineer |pages=27–29 }}</ref><ref>{{cite press release |url=https://tfl.gov.uk/info-for/media/press-releases/2010/september/kings-cross-st-pancras-tube-station-is-stepfree-with-10-new-lifts |title=King's Cross St. Pancras Tube station is step-free with 10 new lifts |date=27 September 2010 |website=tfl.gov.uk |publisher=Transport for London|access-date=30 August 2020 |url-status=live |archive-date=30 August 2020 |archive-url=https://web.archive.org/web/20200830162625/https://tfl.gov.uk/info-for/media/press-releases/2010/september/kings-cross-st-pancras-tube-station-is-stepfree-with-10-new-lifts}}</ref>
