'''Platform screen doors''' ('''PSDs'''), also known as '''platform edge doors''' ('''PEDs'''), are used at some [[train]], [[rapid transit]] and [[people mover]] stations to separate the [[Railway platform|platform]] from train tracks, as well as on some [[bus rapid transit]], [[tram]] and [[light rail]] systems. Primarily used for passenger safety,<ref>{{cite web |url= https://www.wise-geek.com/what-are-platform-screen-doors.htm |title= What Are Platform Screen Doors? |date= 7 February 2022 |website= wiseGEEK |access-date= 23 February 2022 |archive-date= 23 February 2022 |archive-url= https://web.archive.org/web/20220223195130/https://www.wise-geek.com/what-are-platform-screen-doors.htm |url-status= live }}</ref> they are a relatively new addition to many metro systems around the world, some having been retrofitted to established systems. They are widely used in newer [[Asia]]n and [[Europe]]an metro systems, and [[Latin America]]n bus rapid transit systems.

[[File:Crossrail_platform_at_Farringdon.jpg|thumb|upright=1.3|Platform screen doors on the [[Elizabeth line]] at [[Farringdon station|Farringdon]], 2019]]

The idea of platform edge doors dates from as early as 1908, when Charles S. Shute of [[Boston]] was granted a patent for "Safety fence and gate for railway-platforms".<ref>{{Cite patent|country=US|number=915122A|title=Safety fence and gate for railway-platforms.|status=|pubdate=|gdate=1908-05-26|invent1=Shute|inventor1-first=Charles S|url=https://patents.google.com/patent/US915122A/en}} {{Webarchive|url=https://web.archive.org/web/20210929093707/https://patents.google.com/patent/US915122A/en |date=29 September 2021 }}</ref> The invention consisted of "a fence for railway platform edges", composed of a series of pickets bolted to the platform edge, and vertically movable pickets that could retract into a platform edge when there was a train in the station.<ref>{{cite book |author=USA Patent Office|url=https://books.google.com/books?id=orA1hQ58sskC&pg=RA8-PA536 |title=Official Gazette of the United States Patent Office |publisher=U.S. Government Printing Office |year=1872|page=8-PA536|access-date=December 31, 2020|issue=v. 140|archive-date=23 January 2023|archive-url=https://web.archive.org/web/20230123100023/https://books.google.com/books?id=orA1hQ58sskC&pg=RA8-PA536|url-status=live}}</ref> In 1917, Carl Albert West was granted a patent for "Gate for subrailways and the like".<ref>{{Cite patent|country=US|number=1259060A|title=Gate for subrailways and the like.|status=|pubdate=|gdate=1917-06-22|invent1=West|inventor1-first=C.

The first stations in the world with platform screen doors were the ten stations of the [[Saint Petersburg Metro]]'s [[Line 2 (Saint Petersburg Metro)|Line 2]] that opened between 1961 and 1972. The platform "doors" are actually openings in the station wall which supports the ceiling of the platform. The track tunnels adjoining the ten stations' [[island platform]]s were built with [[tunnel boring machine]]s (TBMs), and the island platforms were located in a separate vault between the two track tunnels. Usually, TBMs bore the deep-level tunnels between stations, while the station vaults are dug out manually and contain both the tracks and the platform. However, in the case of the Saint Petersburg Metro, the TBMs bored a pair of continuous tunnels that passed through ten stations, and the stations themselves were built in vaults that only contained the platform, with small openings on the sides of the vault, in order for passengers to access the trains in the tunnels.<ref name=micro>{{cite web |title=Platform screen doors |url=http://www.mic-ro.com/metro/platform-screen-doors.html |website=Metrobits |access-date=30 September 2021 |archive-date=24 January 2021 |archive-url=https://web.archive.org/web/20210124063806/http://mic-ro.com/metro/platform-screen-doors.html |url-status=live }}</ref>

Although the terms are often used interchangeably, '''platform screen doors''' can refer to both full-height and half-height barriers. Full height platform screen doors are total barriers between the station floor and ceiling, while the half-height platform screen doors are referred to as '''platform edge doors''' or '''automatic platform gates''', as they do not reach the ceiling and thus do not create a total barrier. Platform gates are usually only half of the height of the full-screen doors, are chest-height sliding doors at the edge of [[railway platform]]s to prevent passengers from falling off the platform edge onto the [[railway tracks]]. But they sometimes reach to the height of the train. Like full-height platform screen doors, these platform gates slide open or close simultaneously with the train doors. These two types of platform screen doors are presently the main types in the world.

=== Platform screen doors and platform edge doors ===
The [[door]]s help to:
* Prevent people from accidentally falling onto the tracks, getting too close to moving trains, and committing [[suicide]] (by jumping) or [[homicide]] (by pushing).<ref name="Intelligent Transport">{{cite web |url= https://www.intelligenttransport.com/transport-articles/1725/platform-screen-doors/ |title= Platform Screen Doors: No barrier to success |date= 19 April 2007 |website= Intelligent Transport |access-date= 25 September 2019 |archive-date= 25 September 2019 |archive-url= https://web.archive.org/web/20190925180659/https://www.intelligenttransport.com/transport-articles/1725/platform-screen-doors/ |url-status= live }}</ref> Use of platform screen doors in South Korea has reduced rail related suicide by 89%.<ref>{{cite journal |last1=Chung |first1=Yong Woon |last2=Kang |first2=Sung Jin |last3=Matsubayashi |first3=Tetsuya |last4=Sawada |first4=Yasuyuki |last5=Ueda |first5=Michiko |title=The effectiveness of platform screen doors for the prevention of subway suicides in South Korea |journal=Journal of Affective Disorders |date=April 2016 |volume=194 |pages=80–83 |doi=10.1016/j.jad.2016.01.026 |pmid=26803779 |url=https://pubmed.ncbi.nlm.nih.gov/26803779/ |issn=1573-2517}}</ref>
* Prevent or reduce wind felt by the passengers caused by the [[piston effect]] which could in some circumstances make people lose their balance.
* Improve safety—reduce the risk of accidents, especially from trains passing through the station at high speeds.<ref name="Intelligent Transport"/>
* Improve climate control within the station (heating, ventilation, and air conditioning are more effective when the station is physically isolated from the tunnel).<ref name="Intelligent Transport"/>
* Improve security—access to the tracks and tunnels is restricted.<ref name="Intelligent Transport" />
* Lower costs—eliminate the need for [[motorman (locomotive)|motormen]] or [[Conductor (transportation)|conductors]] when used in conjunction with [[automatic train operation]], thereby reducing manpower costs.
* Prevent [[litter]] buildup on the tracks, which can be a fire risk, as well as damage and possibly obstruct trains.<ref>{{cite news |date= 26 May 2006 |title= DIY railway litter patrol banned |url= http://news.bbc.co.uk/1/hi/wales/south_west/5019324.stm |work= BBC News |access-date= 27 September 2019 |archive-date= 29 December 2006 |archive-url= https://web.archive.org/web/20061229025020/http://news.bbc.co.uk/1/hi/wales/south_west/5019324.stm |url-status= live }}</ref>
* Improve the sound quality of platform announcements, as background noise from the tunnels and trains that are entering or exiting is reduced.<ref>{{cite web |url= https://www.researchgate.net/publication/325937164 |title= Effects of platform screen doors on the overall railway system |last1= Abdurrahman |first1= Usman |last2= Jack |first2= Anson |last3= Schmid |first3= Felix |date= January 2018 |website= ResearchGate |access-date= 21 May 2024}}</ref>
* At underground or indoor platforms, prevent the air from being polluted by the fumes caused by friction from the train wheels grinding against the tracks.<ref>PDF on the issue (London Underground): [https://thenorthbank.london/wp-content/uploads/2018/03/Personal-Exposure-and-Air-Quality-in-Northbank-Final.pdf Personal Exposure and Air Quality in Northbank] {{Webarchive|url=https://web.archive.org/web/20181128075250/https://thenorthbank.london/wp-content/uploads/2018/03/Personal-Exposure-and-Air-Quality-in-Northbank-Final.pdf |date=28 November 2018 }}</ref>

Their primary disadvantage of PSDs is their cost. When used to retrofit older systems, they can limit the kind of rolling stock that may be used on a line, because the train doors must fit the spacing of the platform doors, which can result in additional costs, due to the otherwise unnecessary purchase of new rolling stock and consequent depot upgrades. 

Despite delivering an overwhelming improvement to passenger safety at the platform-train interface, platform screen doors do introduce new hazards which must be carefully managed in design and delivery. The principal hazard is entrapment between closed platform doors and the train carriage which, if undetected, can lead to fatality when the train begins to move (see {{section link||Incidents}}). Cases of this happening are rare, and the risk can be minimised with careful design, in particular by interlocking the door system with the signalling system, and by minimising the gap between the closed platform doors and the train body. In some cases active monitoring systems are used to monitor this gap.

{{Anchor|Automatic platform gate|Automatic platform gates}}Half-height platform edge doors, also known as automatic platform gates, are cheaper to install than full-height platform screen doors, which require more metallic framework for support. Some railway operators may therefore prefer such an option to improve safety at railway platforms and, at the same time, keep costs low and non-air-conditioned platforms naturally ventilated. However, these gates are less effective than full platform screen doors in preventing people from intentionally jumping onto the tracks.<ref>{{Cite web |url=http://www.manusa.com/es/sectores/transporte/ |title=Manusa - website on Automatic Platform Gate |access-date=16 November 2010 |archive-url=https://web.archive.org/web/20160826114655/http://www.manusa.com/es/sectores/transporte |archive-date=26 August 2016 |url-status=dead }}</ref> These gates were {{clarify span|first| reason= What about those installed in some Japanese systems, e.g., Yui Rail, Kyushu Shinkansen?|date=May 2022}} in practical use by the [[MTR|Hong Kong MTR]] on the [[Disneyland Resort line]] for the open-air station designs. Most half-height platform edge door designs have taller designs than the ones installed on the Disneyland Resort line.

=== Rope-type platform screen doors ===
There are also rope-type platform screen doors at stations where a number of train types, with different lengths and train door spacings, use the same platforms. The barriers move upwards, rather than sideways, to let passengers through.

Some Japanese, Korean, Chinese and Eastern European countries have stations that use rope-type screen doors, to lower the cost of installation and to deal with the problem of different train types and distances between car doors.

=== Variable-type platform screen doors ===
The first-ever full-height variable screen doors were installed on the underground platforms of [[Ōsaka Station|Osaka Station]], which opened in March 2023, but a few half-height variants can be found on a set installed at the [[Tokaido Shinkansen|Shinkansen]] platforms of [[Shinagawa Station]] in [[Tokyo]]. Their use is rare since they are a much costlier and more complicated alternative to rope-type screen doors. The only difference from the latter is that they move sideways when letting passengers through.

At Osaka Station, the doors are designed as a single block (equivalent to the length of a train car). It consists of five units: one wall-like "parent door" suspended from the top and two sets of glass "child doors". When the train reaches the station, a special scanner on the platform reads the information on the ID tag placed on the train to identify its type and the number of cars. With the type and the number of cars having been instantly identified, each unit will slide automatically to match the configuration of the stopped train. The parent and child doors then slide into the optimal position to align precisely with the position of each car door.<ref name="gov-online.go.jp">{{Cite web |title=Train Station to Install Latest Type of Sliding Platform Screen Doors {{!}} February 2022 {{!}} Highlighting Japan |url=https://www.gov-online.go.jp/eng/publicity/book/hlj/html/202202/202202_10_en.html |access-date=2023-05-20 |website=www.gov-online.go.jp}}</ref>

Since the technology is still new, such doors are still going through testing phases in several countries around the world.<ref>{{Cite web |title=Industry's First Variable Pitch Platform Screen Door |url=https://blog.agilsmartcities.com/tech-in-action/smart-mobility/industry-s-first-variable-pitch-platform-screen-door/ |access-date=2023-05-20 |website=blog.agilsmartcities.com}}</ref>

In 2020, rope-type screen door (RSD) system was installed in [[Vasil Levski Stadium Metro Station]] and [[Opalchenska Metro Station]] of the [[Sofia Metro]] Line 1 and Line 2. “Standard” platform doors cannot be used on those lines because of the differing door layouts between the [[Metrovagonmash 81-717/81-714|81-717/714]] and [[81-740/741]] models used. In total, such rope-type [[safety barrier]]s will be installed on more 10 of the busiest stations on the Line 1 and 2 of the [[Sofia Metro]], providing increased safety for passengers and protecting against accidental falls.<ref>{{Cite web|url=https://trud.bg/%D1%84%D0%B0%D0%BD%D0%B4%D1%8A%D0%BA%D0%BE%D0%B2%D0%B0-%D0%B3%D0%BE%D1%82%D0%BE%D0%B2%D0%B8-%D1%81%D0%B0-%D0%B0%D0%B2%D1%82%D0%BE%D0%BC%D0%B0%D1%82%D0%B8%D1%87%D0%BD%D0%B8%D1%82%D0%B5-%D0%BF%D1%80%D0%B5%D0%B4%D0%BF%D0%B0%D0%B7%D0%BD%D0%B8-%D0%B2%D1%80%D0%B0%D1%82%D0%B8-%D0%BD%D0%B0-%D0%BC%D0%B5%D1%82%D1%80%D0%BE%D1%81%D1%82%D0%B0%D0%BD%D1%86%D0%B8%D1%8F-%D0%BE%D0%BF%D1%8A%D0%BB%D1%87%D0%B5%D0%BD%D1%81%D0%BA%D0%B0/|title=Фандъкова: Готови са автоматичните предпазни врати на метростанция "Опълченска" - Труд|website=trud.bg|access-date=29 September 2021|archive-date=21 June 2022|archive-url=https://web.archive.org/web/20220621091734/https://trud.bg/%D1%84%D0%B0%D0%BD%D0%B4%D1%8A%D0%BA%D0%BE%D0%B2%D0%B0-%D0%B3%D0%BE%D1%82%D0%BE%D0%B2%D0%B8-%D1%81%D0%B0-%D0%B0%D0%B2%D1%82%D0%BE%D0%BC%D0%B0%D1%82%D0%B8%D1%87%D0%BD%D0%B8%D1%82%D0%B5-%D0%BF%D1%80%D0%B5%D0%B4%D0%BF%D0%B0%D0%B7%D0%BD%D0%B8-%D0%B2%D1%80%D0%B0%D1%82%D0%B8-%D0%BD%D0%B0-%D0%BC%D0%B5%D1%82%D1%80%D0%BE%D1%81%D1%82%D0%B0%D0%BD%D1%86%D0%B8%D1%8F-%D0%BE%D0%BF%D1%8A%D0%BB%D1%87%D0%B5%D0%BD%D1%81%D0%BA%D0%B0/|url-status=live}}</ref>

Screen doors are in use at all three [[LINK Train]] stations and the [[Union Station (Toronto)|Union]] and [[Toronto Pearson Terminal 1 Station|Pearson]] stations along the [[Union Pearson Express]] route to [[Toronto Pearson International Airport]] in [[Mississauga, Ontario]]. Platform screen doors will be installed at all stations on the forthcoming [[Ontario Line]].<ref>{{cite web | url=https://www.metrolinx.com/en/projects-and-programs/ontario-line/what-were-building/trains-and-technology | title=Metrolinx - Trains and Technology }}</ref> In addition, as a part of major renovations and expansions to the [[Bloor-Yonge]] interchange, platform screen doors will be installed on both Line 1 platforms. The doors will also be installed on the Line 2 platforms once [[CBTC]] signalling upgrades are made to the line. The addition of such doors at Bloor-Yonge has prompted rumours of a broader system wide rollout, including in the forthcoming [[Scarborough Subway Extension]] and [[Line 1 Yonge–University|Yonge North Subway Extension]], though no confirmation or funding has been announced by the [[Toronto Transit Commission]] or the [[Government of Ontario]].<ref>{{cite web | url=https://toronto.ctvnews.ca/ttc-will-install-platform-edge-doors-on-line-1-platform-at-bloor-yonge-station-as-part-of-1-5b-overhaul-1.6425076 | title=TTC will install platform edge doors on Line 1 platform at Bloor-Yonge Station as part of $1.5B overhaul | date=2 June 2023 }}</ref>

Greater Montreal's forthcoming [[Réseau express métropolitain]] (REM), the 67-kilometre-long driverless complementary suburban rapid transit network opening in five phases between 2023 and 2027<ref>{{cite web | url=https://montreal.citynews.ca/2023/07/31/first-day-of-rem-service-and-first-delays/| title=First day of REM service and first delays | date=31 July 2023}}</ref> will feature screen doors at each of its 26 stations.

With the advent of the REM on the horizon, calls to retrofit platform edge doors in the [[Montreal Metro]] to combat delays arising from overcrowding are becoming more common. If full-height doors were to be installed, it may reduce the difficulty in opening station entrance doors at ground level due to the pressure imbalance caused by passing trains.{{Citation needed|date=November 2020}} Given that there are two different train door layouts on the Montreal Metro, with the older [[MR-73]] trains having 4 doors on each side of the car, and [[MPM-10]] having 3, it is unlikely platform doors will be showing up in the Montreal Metro until the retirement of the MR-73 fleet.

In June 2023, the operator of the [[Vancouver SkyTrain]], [[TransLink (British Columbia)|TransLink]] announced a feasibility study into installing platform screen doors on the [[Expo Line (SkyTrain)|Expo]] and [[Millennium Line|Millennium]] lines. Such installation was previously deemed infeasible, due to SkyTrain's diverse fleet and different door positions. However, with the acquisition of the [[SkyTrain (Vancouver) rolling stock#Alstom_Mark_V|Alstom Mark V trains]], which will replace the ageing [[SkyTrain (Vancouver) rolling stock|Mark I]], the door positions allow for a feasibility study to proceed. The results will be released sometime in 2025.<ref>{{cite web | url=https://dailyhive.com/vancouver/skytrain-platform-screen-doors-trackway-intrusion-engineering-study-translink | title=TransLink studying platform screen doors for SkyTrain stations &#124; Urbanized }}</ref>

However many are starting the process of retrofitting these lines with platform screen gates. 

In addition, many [[bus rapid transit]] systems such as the [[Guangzhou Bus Rapid Transit]] also have stops that are equipped with platform screen doors. Platform screen doors are also present in some tram and light rail stops such as the [[Xijiao line|Xijiao Light rail]], [[Trams in Nanjing|Nanjing tram]] and [[Line 2 (Chengdu Tram)|Chengdu tram]]. 

Several underground high speed railway stations of the [[China Railway High-speed|CRH]] network use platform screen doors set back from the platform edge.

In addition, Fengxian District in Shanghai installed platform gates at a road crossing.

All lines of the [[Véhicule Automatique Léger|VAL]] automated subway system are equipped with platform screen doors at every station, starting with [[Lille Metro|Lille]] subways in 1983. Those also include [[Toulouse Metro|Toulouse]] and [[Rennes Metro|Rennes]] as well as the [[CDGVAL]] and [[Orlyval]] airport shuttles.

[[Paris Métro]]'s line [[Paris Métro Line 14|14]] from [[Saint-Lazare (Paris Métro)|Saint-Lazare]] to [[Bibliothèque François Mitterrand (Paris Métro)|Bibliothèque François Mitterrand]] was inaugurated in 1998 with platform screen doors manufactured by [[Faiveley Transport]]. The new station [[Olympiades (Paris Métro)|Olympiades]] opened with platform screen doors in June 2007. Lines [[Paris Métro Line 1|1]] and [[Paris Métro Line 4|4]] have been retrofitted with platform edge doors, for full driverless automation effective in 2012 and 2023, respectively. Some stations on Line [[Paris Métro line 13|13]] have had platform edge doors since 2010 to manage their overcrowding, after tests conducted in 2006.

Since 30 June 2020, a new kind of vertical platform screen doors, called ''platform curtains'', are being tested on the platform 2bis of [[Vanves–Malakoff station]] (in Paris region) on the [[Transilien Line N]] commuter rail line.

=== Hong Kong ===

As of 5 June 2025, all heavy rail and medium-capacity railway platforms have been equipped with either platform screen doors or automatic platform gates. Automatic platform gates are currently used at all at-grade and elevated stations, while platform screen doors are used in all underground and some at-grade or elevated stations. None of the [[Light Rail (MTR)|light rail]] platforms have platform screen doors or automatic platform gates installed.

The [[MTR Corporation]] had since mid-1996, been studying the feasibility of installing PSDs at the older stations to reduce suicides on the MTR and reduce air-conditioning costs. Platforms 2 and 3 of {{STN|Choi Hung|x}} were chosen for the trial due to them being redundant platforms and receiving low numbers of passengers. Platform screen doors of two and a half cars' length were installed on each of the two platforms during the trial in 1996. As the Kwun Tong line trains consisted of eight cars, it was decided that the PSDs were to be removed to allow for smoother train operations.{{Citation needed|date=January 2024}}

[[File:Tsing Yi Station 2020 06 part2.jpg|thumb|right|[[Tsing Yi station]], along with the other stations of Tung Chung line and Airport Express, were the first stations to have PSDs in normal operation in Hong Kong.]]
With the opening of the {{lnl|MTR|tcl}} and {{lnl|MTR|ae}}, Hong Kong had its first full-height PSDs fully operational in 1998.

The MTR decided in 1999 to undertake the PSD Retrofitting Programme at 74 platforms of 30 select underground stations on the [[Kwun Tong line|Kwun Tong]], [[Island line (MTR)|Island]], and {{lnl|MTR|twl}}s. 2,960 pairs of PSDs were ordered from Gilgen Door Systems. Choi Hung became the first station to receive platform screen doors from this programme in August 2001. The Mass Transit Railway became the first metro system in the world to retrofit PSDs on a transit system already in operation.<ref>{{cite web|url=http://www.info.gov.hk/gia/general/200501/05/0105194.htm|title=LCQ16: Retrofitting of PSDs at MTR stations to be completed by 2006|publisher=HKSAR Government Information Centre|date=5 January 2005|access-date=17 June 2007|archive-date=10 March 2012|archive-url=https://web.archive.org/web/20120310055615/http://www.info.gov.hk/gia/general/200501/05/0105194.htm|url-status=live}}</ref> The program was completed in March 2006.<ref name=legco12>{{cite web|title=Updated background brief on installation of platform screen doors and automatic platform gates at railway stations|url=http://www.legco.gov.hk/yr11-12/english/panels/tp/tp_rdp/papers/tp_rdp0302cb1-1156-e.pdf|publisher=Legislative Council|date=2 March 2012|access-date=24 December 2016|archive-date=31 October 2019|archive-url=https://web.archive.org/web/20191031000129/https://www.legco.gov.hk/yr11-12/english/panels/tp/tp_rdp/papers/tp_rdp0302cb1-1156-e.pdf|url-status=live}}</ref> All subsequent new stations or platforms installed with PSDs also used those manufactured by Gilgen Door Systems, until the cross-harbour extension of the East Rail Line which used platform screen doors manufactured by Fangda Group.<ref>{{Cite web |title=采用方大轨道交通屏蔽门系统的香港东铁线过海段正式开通 |url=http://www.fangda.com/news/index3863.html |archive-url=https://web.archive.org/web/20240106203011/http://www.fangda.com/news/index3863.html |archive-date=2024-01-06 |access-date=2024-01-06 |website=China Fangda Group Co., Ltd.}}</ref>

[[File:Sunny Bay Station platforms 2022 05 part4.jpg|thumb|right|Sunny Bay station was the first station in Hong Kong to have PEDs.]]
The opening of the {{STN|Sunny Bay|x}} and {{STN|Disneyland Resort|x}} stations in 2005 also meant the first platform-edge doors entering operation for the MTR network. These doors are currently the lowest in the entire network of being at around {{cvt|1.2|m|ftin}} high, compared to {{cvt|1.55|m|ftin}} on the Kwun Tong, Tsuen Wan, Island and Tung Chung lines and {{cvt|1.7|m|ftin}} on the [[Tuen Ma line|Tuen Ma]] and {{lnl|MTR|sil}}s.

In 2006, the MTR began studying ways to introduce barriers at above-ground and at-grade stations, which was considered more complicated as those stations were naturally ventilated and the introduction of full-height platform screen doors would entail the installation of air conditioning systems. In 2008, the corporation decided to install automatic platform gates (APGs) at eight stations (the MTR Corporation Limited and KCR Corporation had been operationally merged since 2007, but KCR stations were not included in this study).<ref name=legco12/> The eight stations were retrofitted with APGs in 2011.

From July 2000 to December 2013, the MTR Corporation collected a surcharge of 10 [[Hong Kong dollar|cent]]s from each [[Octopus card|Octopus]]-paying passenger to help pay for the installation of PSDs and APGs. Over HK$1.15 billion was collected in total.<ref>{{cite news|last1=Feng|first1=Frank|title=Hong Kong MTR passengers to be spared platform screen door costs|url=http://www.scmp.com/news/hong-kong/education-community/article/1842551/hong-kong-mtr-passengers-be-spared-platform|work=South China Morning Post|date=22 July 2015|access-date=24 December 2016|archive-date=8 November 2020|archive-url=https://web.archive.org/web/20201108093658/http://www.scmp.com/news/hong-kong/education-community/article/1842551/hong-kong-mtr-passengers-be-spared-platform|url-status=live}}</ref>

Platform screen doors were also installed on all platforms of the [[West Rail line]] (now part of the [[Tuen Ma line]]), then built by the [[Kowloon-Canton Railway Corporation]] (KCRC) before the [[MTR–KCR merger]]. The [[Ma On Shan line]] did not have gates upon opening even though it was built at the same time as the West Rail; they were eventually added from 2014 to 2017 prior to the opening of the first phase of the Tuen Ma line on 14 February 2020.

The installation of platform screen doors in Hong Kong has been effective in reducing railway injuries and service disruptions.<ref>{{cite journal|last1=Law|first1=C.K.|last2=Yip|first2=P.S.F.|title=An economic evaluation of setting up physical barriers in railway stations for preventing railway injury: evidence from Hong Kong|journal=[[Journal of Epidemiology and Community Health]]|date=30 January 2011|volume=65|issue=10|pages=915–920|doi=10.1136/jech.2010.115188|pmid=21282146|hdl=10072/61569|s2cid=41988348|hdl-access=free}}</ref>

The then-longest set of platform screen doors in the world can be found in [[East Tsim Sha Tsui station]], where it first served the {{lnl|MTR|eal}} when 12-car [[MTR Metro Cammell EMU (AC)|MLR]] trains were still in service.<ref>{{cite web|title=東鐵不裝幕門被轟為慳錢|url=http://hk.apple.nextmedia.com/news/art/20050704/5021127|publisher=[[Apple Daily]]|language=zh|date=4 July 2005|access-date=6 May 2016|archive-date=20 December 2016|archive-url=https://web.archive.org/web/20161220160701/http://hk.apple.nextmedia.com/news/art/20050704/5021127|url-status=live}}</ref> Following the completion of the [[Kowloon Southern Link]] and handing over of the station to the {{lnl|MTR|wrl}} (now part of the Tuen Ma line), the subsequent reduction of train length from 12 to 7 cars caused many of the screen doors to be put out of service, although the trains were lengthened to eight cars in May 2018.

The West Rail line (now part of Tuen Ma line), had all stations installed with APGs, and another constituent line of the Tuen Ma line, the Ma On Shan line, had its final APG installed enter service on 20 December 2017.

The last non-tram/light rail stations in Hong Kong without platform screen doors or gates are all on the {{lnl|MTR|eal}}, a former KCR line not part of the MTR APG retrofitting programmes. The [[KCR Corporation]] found it difficult to install APGs because of the wide curves of the platforms and large gaps of their platforms, especially in {{STN|University|x|MTR}}, {{STN|Lo Wu|x}}, and {{STN|Mong Kok East|x}} station. However, these remaining thirteen stations are all being retrofitted by [[Kaba Group|Kaba]] as part of the [[Sha Tin to Central Link]] project. The APGs are estimated to be at around {{cvt|1.8|m|ftin}} high.<ref>{{cite web|title=Contracts |url=http://www.mtr-shatincentrallink.hk/en/construction/contracts.html |website=Sha Tin to Central Link |publisher=MTR Corporation |access-date=23 November 2015 |url-status=dead |archive-url=https://web.archive.org/web/20160304194157/http://www.mtr-shatincentrallink.hk/en/construction/contracts.html |archive-date=4 March 2016}}</ref> Adding APGs to the East Rail Line platforms requires platform strengthening with rebars and brackets as the gates, combined with heavy winds, can greatly increase structural load on the platform structure. Also extensive waterproofing work is needed as many of these platforms are directly exposed to the elements.

The [[Lahore Metro]] utilises half-height platform edge doors at elevated stations and full-height platform screen doors at underground stations. Many [[bus rapid transit]] systems have full-height platform screen doors installed, including the [[Lahore Metrobus]], [[Rawalpindi-Islamabad Metrobus]], [[Multan Metrobus]], [[TransPeshawar]], and [[Karachi Breeze]].

[[Park Pobedy (Saint Petersburg Metro)|Park Pobedy]] (Russian: Парк Победы) is a station of the [[Saint Petersburg Metro]] that was the first station in the world with platform doors. The station was opened in 1961. Later, nine more stations of this type were built in [[Leningrad]] (nowadays [[Saint Petersburg]]): [[Petrogradskaya]] (Russian: Петроградская), [[Vasileostrovskaya]] (Russian: Василеостровская), [[Gostiny Dvor (Saint Petersburg Metro)|Gostiny Dvor]] (Russian: Гостиный двор), [[Mayakovskaya (Saint Petersburg Metro)|Mayakovskaya]] (Russian: Маяковская), [[Ploshchad Alexandra Nevskogo I]] (Russian: Площадь Александра Невского-1), [[Moskovskaya (Saint Petersburg Metro)|Moskovskaya]] (Russian: Московская), [[Yelizarovskaya (Saint Petersburg Metro)|Yelizarovskaya]] (Russian: Елизаровская), [[Lomonosovskaya (Saint Petersburg Metro)|Lomonosovskaya]] (Russian: Ломоносовская), and [[Zvyozdnaya]] (Russian: Звёздная).

There was an electronic device to ensure that the train stopped with its doors adjacent to the platform doors; they were installed so that driverless trains could eventually be used on the lines.<ref>{{cite magazine |editor-first=B.W.C. |editor-last=Cooke |date=November 1959 |title=Sliding Doors on Platform Edge |magazine=[[The Railway Magazine]] |volume=105 |issue=703 |page=796 |publisher=Tothill Press |location=Westminster }}</ref> Line 2 uses GoA2 [[automatic train operation]] to make this easier, however, Line 3 does not. Unlike other platform screen doors, which are lightweight units with extensive glazing installed on a normal platform edge, the St Petersburg units give the appearance of a solid wall with heavyweight doorways and solid steel sliding doors, similar to a bank of elevators in a large building, and the train cannot be seen entering from the platform; passengers become familiar with the sound alone to indicate a train arrival.

In May 2018, two other similar stations were opened: [[Zenit (Saint Petersburg Metro)|Novokrestovskaya (now Zenit)]] and [[Begovaya (Saint Petersburg Metro)|Begovaya]]. Unlike the first ten stations that were built, these stations utilize glass screen doors, allowing the train to be seen entering from the platform, like most other systems. It is unclear why platform doors were installed here as they are absent in all other metros in Russia, the [[Commonwealth of Independent States|CIS]] (except that of Minsk, shown above), or the former [[Eastern Bloc|Eastern bloc]] (excluding Sofia, also shown above, albeit on a line with equipment incompatible with that of the typical Eastern bloc metro).

The only other platform doors in Russia are found on the [[Sheremetyevo International Airport]] people mover.

The [[Mass Rapid Transit (Singapore)|Mass Rapid Transit]] (MRT) was the first [[rapid transit]] system in Asia to incorporate platform screen doors in its stations in 1987.<ref>[http://www.platformscreendoors.com/psd/projects/massrapid.php Westinghouse Platform Screen Doors - Completed Projects] {{webarchive |url=https://web.archive.org/web/20080213223641/http://www.platformscreendoors.com/psd/projects/massrapid.php |date=13 February 2008 }}</ref> Full height PSDs mainly manufactured by [[Westinghouse Rail Systems|Westinghouse]] are installed at all underground MRT and sub-surface stations, while half-height platform screen doors were retrofitted into all elevated stations by March 2012. The [[Light Rail Transit (Singapore)|LRT stations]] at [[Bukit Panjang LRT line|Bukit Panjang]], [[Sengkang LRT line|Sengkang]] and [[Punggol LRT line|Punggol]] lack physical doors, only barriers with openings where the doors go (excluding the now-closed [[Ten Mile Junction LRT station|Ten Mile Junction station]], which had full height doors) and vary in size according to their location on the platform.{{citation needed|date=September 2021}}

There are two variants of the full-height platform screen doors in use. The first variant, made by Westinghouse, was installed at all underground stations along the [[North South MRT line|North South line]] and the [[East West MRT line|East West line]] from 1987 to the completion of the initial system in 1990. The second variant incorporating more glass on the doors has since been used on all lines thereafter.{{citation needed|date=September 2021}}

Considered a novelty at the time of its installation, platform screen doors were introduced primarily to minimise hefty air-conditioning costs, especially since elevated stations are not air-conditioned and are much more economical to run in comparison.<ref name="Intelligent Transport" /> The safety aspects of these doors became more important in light of high-profile incidents where individuals were injured or killed by oncoming trains.<ref>{{Cite web |last=NEE |first=Insight Down South SEAH CHIANG |title=Suicide rate climbs despite good times |url=https://www.thestar.com.my/opinion/letters/2007/08/18/suicide-rate-climbs-despite-good-times |access-date=2022-07-16 |website=The Star |date=18 August 2007 |language=en |archive-date=16 July 2022 |archive-url=https://web.archive.org/web/20220716165314/https://www.thestar.com.my/opinion/letters/2007/08/18/suicide-rate-climbs-despite-good-times/ |url-status=live }}</ref> In 2008, authorities began the process of retrofitting existing elevated stations with half-height screen doors.<ref>{{Cite web |title=Platform screen doors for all above-ground MRT stations by 2012 |url=https://www.asiaone.com/News/AsiaOne+News/Singapore/Story/A1Story20080125-46683.html |access-date=2022-07-16 |website=www.asiaone.com |archive-date=16 July 2022 |archive-url=https://web.archive.org/web/20220716171833/https://www.asiaone.com/News/AsiaOne+News/Singapore/Story/A1Story20080125-46683.html |url-status=live }}</ref> However, [[Land Transport Authority]] stated that the retrofit was not motivated by the need to make the stations safe, "but to prevent system-wide delay and service disruption and to reduce the social cost to all commuters caused by track intrusions."<ref>{{Caselaw source|case=[2013] SGHC 286 - BNJ (suing by her lawful father and litigation representative, B) v SMRT Trains Ltd and another|other_source1=eLitigation|other_url1=https://www.elitigation.sg/gdviewer/s/2013_SGHC_286}}</ref> The retrofit was completed in 2012.<ref>{{Cite web |title=LTA completes installing elevated MRT station screen doors early |url=https://www.channelnewsasia.com/singapore/lta-completes-installing-elevated-mrt-station-screen-doors-early-1890761 |access-date=2022-07-16 |website=CNA |language=en |archive-date=16 July 2022 |archive-url=https://web.archive.org/web/20220716172025/https://www.channelnewsasia.com/singapore/lta-completes-installing-elevated-mrt-station-screen-doors-early-1890761 |url-status=live }}</ref>

The Elizabeth line, the new cross-city line for [[London]] (delivered as the [[Crossrail]] Project) has platform screen doors on each of the sixteen sub-surface platforms of its central section.<ref>{{cite web |url=https://www.crossrail.co.uk/project/routeway/platform-screen-doors |title=Floor-to-ceiling Platform Screen Doors |publisher=Crossrail |access-date=8 February 2021 |archive-date=27 February 2021 |archive-url=https://web.archive.org/web/20210227184014/https://www.crossrail.co.uk/project/routeway/platform-screen-doors |url-status=dead }}</ref> Each platform has twenty-seven doors which align with the twenty-seven saloon doors of the new [[British Rail Class 345]] which operates the service. The doors form a {{cvt|2.5|m|ftin}} high glass and steel screen the entire length of the platform. The door opening is {{cvt|2.1|m|ftin}} wide, and the system includes integrated passenger information and digital advertising screens. The system is unusual in that the trains served are full-sized commuter trains, larger and longer than the trains of metro systems more commonly equipped with platform screen doors. In total, some 4&nbsp;km of platform screen is provided.

Platform screen doors are rare in the United States, and are nearly exclusively found on small-scale systems. Honolulu's [[Skyline (Honolulu)|Skyline]], which began operations in June 2023, is the first and only large-scale publicly-run metro system in the country to feature platform screen doors, with platform gates at every station manufactured by [[Allegion|Stanley Access Technologies]].<ref>{{Cite web |title=Rail News - HART to install safety gates at 21 rail stations.

[[People mover]]s, systems that ferry passengers across large distances they would otherwise walk, make use of platform screen doors. These systems are common at airports such as [[Hartsfield–Jackson Atlanta International Airport]] and [[Denver International Airport Automated Guideway Transit System|Denver International Airport]]. The [[Port Authority of New York and New Jersey]] uses full height platform screen doors at two of its systems: [[AirTrain JFK]] and [[AirTrain Newark]] (serving [[John F.
