The '''Bucharest Metro''' ({{langx|ro|Metroul din București}}) is an underground [[rapid transit]] system that serves [[Bucharest]], the capital of [[Romania]]. It first opened for service on 16 November 1979.<ref name="history">{{cite web |url=http://www.metrorex.ro/metrorex_history_p780-2 |title=Metrorex – Metrorex history |publisher=Metrorex |access-date=2014-05-08 |archive-date=3 March 2016 |archive-url=https://web.archive.org/web/20160303181957/http://www.metrorex.ro/metrorex_history_p780-2 |url-status=dead }}</ref> The network is run by Metrorex.

The Bucharest Metro has five lines ([[M1 Line (Bucharest Metro)|M1]], [[M2 Line|M2]], [[M3 Line|M3]], [[Bucharest Metro Line M4|M4]], and [[Bucharest Metro Line M5|M5]]). The newest metro line, M5, was opened in 2020.<ref>{{cite web | url=https://metroulbucuresti.com/linia-m5/ | title=Linia M5 Râul Doamnei - Eroilor }}</ref> A sixth metro line, [[Bucharest Metro Line M6|M6]] line, is currently under construction. 

As of 2024, Bucharest Metro is the only metro system in Romania; with a second one, the [[Cluj-Napoca Metro]], being under construction.

==Overview==
Bucharest Metro is part of the [[Transport in Bucharest|Bucharest public transport network]] which also includes STB, which operates a complex network of [[bus]]es, [[trolleybus]]es, [[light rail]] and [[tram]]s. STB is Bucharest's surface public network system, while Bucharest Metro operates underground (a short stretch between [[Dimitrie Leonida metro station|Dimitrie Leonida]] and [[Tudor Arghezi metro station|Tudor Arghezi]] metro stations is the only portion of the Bucharest Metro that does not run underground). Until relatively recently, car ownership in Romania was not common: during the first part of the 20th century few people had cars, and the subsequent communist regime installed after World War II restricted personal car use. The public transportation system in Bucharest has its origin in the 19th century, with the city introducing [[horse-drawn tram]]s in 1872.<ref>{{Cite web|url=https://www.rador.ro/2022/12/28/28-decembrie-1872-pe-strazile-bucurestene-aparea-primul-tramvai-tras-de-cai/|title=28 decembrie 1872, pe străzile bucureștene apărea primul tramvai tras de cai &#124; Agenția de presă Rador|date=28 December 2022}}</ref>

[[File:Statia Metrou Titan.jpg|thumb|[[Titan metro station]] on [[Bucharest Metro Line M1|M1 Line]]]]
[[File:Statie Metrou - Grozavesti.jpg|thumb|[[Grozăvești metro station]]]]
The first proposals for a metro system in Bucharest were made in the early part of the 20th century, by the Romanian engineers [[Dimitrie Leonida]] and [[Elie Radu]].<ref name="agir">{{cite web |url=http://www.agir.ro/univers-ingineresc/numar-17-2009/30-de-ani-de-exploatare-a-metroului-bucurestean_2599.html|title=30 de ani de exploatare a metroului bucurestean|publisher=agir.ro|date=August 2009|language=ro}}</ref>

The earliest plans for a Bucharest Metro were drafted in the late 1930s, alongside the general plans for urban modernization of the city.<ref>{{cite web|url=http://www.historia.ro/exclusiv_web/general/articol/metroul-bucurestean-10-lucruri-care-ar-trebui-sa-le-cunosti|title=Metroul bucureștean, 10 lucruri pe care ar trebui să le cunoști|publisher=historia.ro|access-date=2014-07-29|language=ro|archive-date=9 August 2014|archive-url=https://web.archive.org/web/20140809115758/http://www.historia.ro/exclusiv_web/general/articol/metroul-bucurestean-10-lucruri-care-ar-trebui-sa-le-cunosti|url-status=dead}}</ref> The outbreak of [[World War II]], followed by periods of political tensions culminating with the installation of [[Communist Romania|communism]], put an end to the plans.<ref>{{cite web |url=http://www.cotidianul.ro/bucurestiul-mileniului-trei-imaginat-in-1930-197263/|title=Bucureștiul mileniului trei imaginat în 1930|date=17 October 2012 |publisher=cotidianul.ro|access-date=2014-07-29|language=ro}}</ref>

By 1970, the public transport system (ITB) was no longer adequate due to the fast pace of urban development, although the system was the fourth-largest in Europe. A commission was set up, and its conclusion pointed to the necessity of an underground transit system that would become the Bucharest Metro. The plan for the first line was approved on 25 November 1974 as part of the next [[Five-year plans of Romania|five-year plan]] and the construction on the new metro system started on 20 September 1975.<ref name="planuri">{{cite web |url=http://www.b365.ro/istoricul-metroului-bucurestean-de-la-proiect-la-magistrala-7_184826.html|title=Ce nu știați despre metroul bucureștean: De la planurile din 1909, la Magistrala 7|date=19 November 2012|access-date=2014-07-29|language=ro}}</ref>

The network was not built in the same style as other Eastern European systems.<ref name="agir"/> Firstly, the design of the stations on the initial lines was simple, clean-cut modern, with most stations being relatively austere, without excessive additions such as mosaics, awkward lighting sources or elaborate and ornate decoration. The main function of the stations was speed of transit and practicality. Secondly, the trainsets themselves were all constructed in Romania and did not follow the Eastern European style of construction.<ref name="urbanrail">[http://www.urbanrail.net/eu/ro/buc/bucurest.htm Bucharest Metro] at urbanrail.net</ref> Each station usually followed a colour theme (generally white – in [[Piața Unirii metro station|Unirii 2]] (Union 2), [[Piața Victoriei metro station|Victoriei 1]] (Victory 1), [[Armata Poporului metro station|Lujerului]]; but also light blue – in [[Obor metro station|Obor]], [[Universitate metro station|Universitate]] (University), and [[Gara de Nord]] (North Train Station); orange – in [[Tineretului metro station|Tineretului]] (Of Youth Station); green – in [[Grozăvești metro station|Grozăvești]]), and an open plan. No station was made to look exactly like any other. Despite this, many stations are rather dark, due to the policies of energy economy in the late 1980s, with later modernisations doing little to fix this problem. 

During the 1980s, the metro network expanded very rapidly, at a rate only surpassed by that of the [[Mexico City Metro]].<ref name="auto2">{{Cite web|url=https://observator.tv/social/inedit-cateva-lucruri-pe-care-sigur-nu-le-stiai-despre-metroul-bucurestean-119263.html|title=10 lucruri pe care nu le știai despre metroul bucureștean|last=Juncu|first=Diana|website=OBSERVATOR.TV|access-date=2018-07-07}}</ref> Two more lines were opened during this decade, M3 in 1983, and M2 in 1986. 
After the 1989 [[Romanian Revolution]], the socioeconomic and political turmoil of the 1990s largely stagnated the expansion of the metro. Advancement of the construction was difficult; for example, the [[Gorjului metro station| Gorjului]] metro station was built in two stages (1994 outbound platform and 
1998 inbound platform), and as a consequence the two platforms and associated vestibules were built with different materials and with different colour schemes. The fourth metro line, M4, for which construction was started in September 1989 (shortly before the Revolution), was finally opened in 2000. After Romania joined the [[European Union]] in 2007, EU funds helped with the expansion of the metro.<ref>{{Cite web |title=Finanțări europene: A fost deschisă Magistrala 5 de metrou |url=https://mfe.gov.ro/finantari-europene-a-fost-deschisa-magistrala-5-de-metrou/ |access-date=May 28, 2025 |website=Ministerul Investițiilor și Proiectelor Europene |language=ro}}</ref> The M5 line was opened in 2020, and the M6 line is under construction.

Due to [[Bucharest]] being one of the largest cities in the region, the network is larger than those of [[Prague Metro|Prague]], [[Warsaw Metro|Warsaw]], [[Budapest Metro|Budapest]] or [[Sofia Metro|Sofia]]. Bucharest Metro is also larger than some other metro systems within the [[European Union]], such as: [[Rome Metro]], [[Copenhagen Metro]], [[Helsinki Metro]], [[Amsterdam Metro]], [[Brussels Metro]], and [[Lisbon Metro]]. In addition, there are plans to extend the existing lines and to open two more lines: M7 and M8.<ref name="auto1"/><ref>{{cite web | url=https://arenaconstruct.ro/ce-linii-noi-de-metrou-vom-avea-in-bucuresti/ | title=Ce linii noi de metrou vom avea in Bucuresti | date=18 October 2023 }}</ref> Bucharest Metro opened in 1979 (line M1), shortly after [[Brussels Metro]] (1976), [[Vienna U-Bahn]] (1976) and [[Amsterdam Metro]] (1977), and before [[Helsinki Metro]] (1982) or [[Copenhagen Metro]] (2002).

Large stations which connect with other lines, such as Piața Victoriei, have two terminals, and each terminal goes by a different name (Victoriei 1 and Victoriei 2). On the official network map, they are shown as two stations with a connection in between, even though, in fact – and for trip planners – they are a single station with platforms at different levels. There is one exception: Gara de Nord 1 and Gara de Nord 2 are separate stations (although linked through a subterranean passage, the traveller is required to exit the station proper and pay for a new fare at the other station, thus leaving the system), passengers being required to change trains at Basarab.

Generally, the underground stations feature large interiors.<ref name="planuri"/> The largest one, [[Piața Unirii metro station|Piata Unirii]], is cathedral-like, with vast interior spaces, hosting retail outlets and fast-food restaurants and has an intricate network of underground corridors and passageways.

Metrorex is the Romanian company which runs the Bucharest Metro. It is fully owned by the [[Romanian Government]] through the Ministry of Transportation.<ref>{{Cite web |title=Obiective investitii - Metrou |url=https://www.mt.ro/web14/informatii-de-interes-public/investitii/1867-proiecte-investitii-metrou |access-date=2023-12-31 |website=www.mt.ro}}</ref><ref>{{Cite web |title=METROREX |url=http://www.metrorex.ro/about_metrorex_p1343-2 |access-date=2023-12-31 |website=www.metrorex.ro}}</ref> There were plans to merge the underground and overground transportation systems into one authority subordinated to the City of [[Bucharest]], however these plans did not come to fruition.

== Infrastructure and network == 
{{See also|List of Bucharest metro stations}}
[[File:Tudor Arghezi Station - Metrorex - M2 - 2024.jpg|thumb|[[Tudor Arghezi metro station]], which is latest station to be opened, in 2023, and is the newest terminus of the [[Bucharest Metro Line M2|M2 Line]] from [[Pipera metro station|Pipera]].]]
As of 2023, the entire network runs underground, except for a stretch between Dimitrie Leonida and Tudor Arghezi stations on the southern end of the M2 line. All metro stations are underground, except two (Berceni and Tudor Arghezi, which are the former terminus and current terminus, respectively, of line M2). The network is served by six depots, two being located above ground (IMGB and Industriilor) and four underground (Ciurel, Străulești, Pantelimon and Valea Ialomiței) and smaller additional works at Gara de Nord 1, Eroilor 1, Republica, Parc Drumul Taberei, Favorit, Anghel Saligny, Crângași, Piața Victoriei 2 and Dristor 2 stations.

There are two connections between the Metro network and the [[Romanian Railways]] network, one at Berceni (connecting to the Bucharest Belt Ring), the other at Ciurel (connecting via an underground passage to the Cotroceni-Militari industrial railway). However, the latter connection is currently unused and mothballed. The metro network and the national rail network have almost similar [[track gauge]] (using the {{track gauge|1432mm|disp=/}} vs {{track gauge|sg|disp=/}}) and [[loading gauge]] but not the same electrification system (the metro uses {{750 V DC|conductor=y}}{{efn|Overhead lines with same voltage employed only in works, depots and selected tunnels.}} whereas the Romanian Railways use {{25 kV 50 Hz}} [[overhead line]]s) making it possible for new metro cars to be transported cross country as unpowered railway cars. This distinction is also seen in the pre-2007 separation between the [[MTR]] and the former [[Kowloon–Canton Railway|KCR]] network in Hong Kong (see [[Track gauge in Hong Kong]]).

=== Signalling system ===
{{More citations needed section|date=September 2022}}
There are multiple signalling systems used. Line 2, the first one that has been modernized, uses Bombardier's CITYFLO 350 [[automatic train control]] system. It ensures the protection ([[Automatic train protection|ATP]]) and operation ([[Automatic train operation|ATO]]) of the new Bombardier Movia trains.

The system uses an IPU ([[Interlocking]] processing unit), TI21-M [[track circuit]]s and EbiScreen workstations. Signals have been kept only in areas where points are present, meaning that the route has been assigned and the driver can use cab signalling.
Trains are usually operated automatically, with the driver only opening and closing the doors and supervising the operation.
Other features include auto turnback and a [[balise]] system, called PSM (precision stop marker). This ensures that the train can stop at the platform automatically.

On line 3, the ATC system has been merged with the [[Punktförmige Zugbeeinflussung|Indusi]] system. Signals are present in point areas and platform ends. Along with the three red-yellow-green lights, the white ATP light has been added. Optical routes can be assigned, meaning that a train gets a green light (permission to pass the signal) only after the next signal has been passed by the train ahead, or a yellow light, meaning that the signal can be passed at low speed. [[Automatic block signaling|Automatic block signals]] have been removed.

Line 4 uses [[Siemens]]'s TBS 100 FB ATC system.

Line 5 uses Alstom's Urbalis 400 [[Communications-based train control]] system.<ref>{{Cite web|url=https://www.alstom.com/press-releases-news/2020/9/alstom-salutes-opening-bucharest-metro-line-5|title = Alstom salutes the opening of the Bucharest Metro Line 5}}</ref>

=== Hours of operation ===
Trains run from 5 AM to 11 PM every day. The last trains on M1, M2 and M3 wait for the transfer of the passengers between lines to complete, before leaving [[Piața Unirii metro station|Piața Unirii]] station.<ref>{{cite web |url=http://www.metrorex.ro/schedule_p775-2 |title=Metrorex – Schedule |publisher=Metrorex |access-date=2014-05-07}}</ref>

=== Headway ===
At rush hour, trains run at 4–6-minute intervals on lines 1 and 3, at 1-3 minute intervals on line 2, and at 7–8-minute on line 4; during the rest of the day, trains run at 8-minute intervals on lines 1 and 3, at 7-9 minute intervals on line 2 and at 10-minute intervals on line 4.<ref name="features" />

=== Fares and tickets ===
[[Image:METROREX ticket.jpg|thumb|Metrorex ticket]]
Public transport in Bucharest is heavily subsidized, and the subsidies will increase, as the City Council wants to reduce traffic jams, pollution and parking problems and promote public transport.{{Citation needed|date=March 2013}} Like the [[RATB|STB]], the metro can get crowded during morning and evening rush hours. The network uses [[magnetic stripe card]]s, that are not valid for use on trams, buses or trolleybuses. Payment by contactless credit cards is available directly at the turnstiles. One tap will take 5 RON, the equivalent of one trip. For multiple validations with the same card, tap the plus button. Starting from 29 July 2021 Metrorex began replacing the magnetic stripe cards with contactless ones for weekly and monthly passes.<ref>{{Cite web|title=Metrorex introduce propriul card contactless pentru abonamentul săptămânal, lunar sau anual|url=https://www.digi24.ro/stiri/actualitate/social/metrorex-introduce-propriul-card-contactless-pentru-abonamentul-saptamanal-lunar-sau-anual-1614307|access-date=2021-11-19|website=digi24.ro|date=28 July 2021 |language=ro}}</ref> As of November 2021 most of the cards with have been replaced with contactless ones. 
<!-- 
==== Card Activ ====
From July 2006, the public transport in Bucharest was to be coordinated by the Metropolitan Transportation Authority. Hhowever, this was postponed indefinitely. The ticketing systems for ground and subway transportation are currently being unified, with a new [[RFID]] card system being deployed across the network, with the old cards slated to be discontinued.{{needs update|date=April 2021}}

The newer RFID card system is managed by [[RATB]] and RFID cards can only be obtained from RATB kiosks. The system is called Card ACTIV. RFID cards are given away free of charge, but only if one agrees to have one's personal data (name and personal numeric code) imprinted on the card. Along with the personal data, as one uses the transport system, cost and usage data is collected in a centralised database. [[RATB]] claims this data is used only for improving the transport system. Only the person with the name imprinted on the card may use that card if used in combination with a monthly pass. If the card is lost, the lost card can be canceled and the traveler, for a small fee, can obtain a new card with the remaining credit on it. Anonymous RFID cards can also be obtained for a small fee and they can be used by multiple travelers.

One must purchase a pass or credit to actually use the Card ACTIV on the underground or ground network. Also, these newer cards currently support for the metro network only monthly passes and a form of payment by trip, where travelers can buy credit (at RATB kiosks and online). The full cost of a trip – 2 [[Romanian leu|lei]] (€0.47) is then deducted from the card whenever entering the metro network, regardless of the number of times a traveler enters the metro network in a given time interval. Because of this limitation, the 10 trip older-style metro card (see below) remains the most cost-effective solution for the casual traveler.

The RFID cards can also be recharged online at the RATB Online website.<ref>{{cite web |url=https://online.ratb.ro/ |title=RATB Online |publisher=[[Regia Autonomă de Transport București]] (RATB) |access-date=2014-05-07}}</ref> At the website, a user can recharge the card's electronic wallet with an arbitrary amount of money, in increments of 1 [[Romanian leu|RON]] or extend the existing monthly passes, for both underground and surface transport.

''Due to unknown problems that [[Metrorex]] had with RATB, the Activ cards can no longer be used on the metro as of spring 2014. Due to 20 million euros of debt RATB had to Metrorex, the cards system has been abolished truly making a mark at the rampant corruption present in the City.'' -->

These projects are financed by the EU, with the exception of M6.2 which is financed by a loan from [[JICA]].

=== Other proposals ===
Metrorex is also planning the following new lines, routes and stations:

**[[Giulești]] between [[Crângași]] and Basarab.

== Rolling stock ==
The Bucharest Metro uses three types of trainsets:<ref name="features" /><ref>{{Cite web|url=https://www.economica.net/in-cele-mai-noi-statii-de-metrou-vor-circula-cele-mai-vechi-trenuri-metrorex_130788.html|title=În cele mai noi staţii de metrou vor circula cele mai vechi trenuri Metrorex|date=31 December 2016|website=Economica.net}}</ref>
* [[Astra IVA]] (BM1) – 84 trainsets (504 cars), built between 1976 and 1992. Only 15 trainsets (90 cars) are still operating. Until now, 69 trainsets (414 cars) have been retired from service. The remaining of 15 trainsets which are still active were refurbished by Metrorex and Alstom Transport România in 2011–2013.<ref name="Metrorex" /> In the past, they were used on M1, M2, M3 and M4. Presently, they are still used on M4 and occasionally on M3.
* [[Bombardier Transportation|Bombardier]] Movia 346 (BM2, BM21) – 44 trainsets (264 cars), built between 2002 and 2008, used on M1, M2, M3 and M5 (a modification of the Swedish [[SL C20]] metro train type)
* [[Construcciones y Auxiliar de Ferrocarriles|CAF]] Inneo (BM3) – 24 trainsets (144 cars), built between 2013 and 2016, used on M2.
* [[Alstom Metropolis]] [[Alstom Metropolis BM4|(BM4)]] - 13 trainsets built in [[Taubaté]] between 2023 and 2025, will be used on M5 when they will finish testing.

| style="vertical-align: top;" | The Romanian designed [[Astra IVA]] trains, built in [[Arad, Romania|Arad]], are made up of various trainsets (''rame'') connected together. Each trainset is made up of two permanently connected train-cars (B′B′+B′B′ formation) that can only be run together. The Astra IVA rolling stock is approaching the end of its service life, so it is gradually being phased out. They are used on the Bucharest Metro Lines M3 (only on weekdays due to lack of available Bombardier trainsets) and M4.

Bombardier trains are used on all lines, except line [[Bucharest Metro Line M4|M4]]. These trains were built in two series: the first 18 trains (BM2) and the last 26 trains (BM21). BM21 trains have some improvements compared to BM2 trains. These trains have electronic displays at the end of the rail cars and more grab bars.

The subway livery for Bucharest is either white with two yellow or red horizontal stripes below the window for the Astra trains, stainless steel with black and white for the Bombardier trains, or stainless steel with blue and white for the CAF trains.

All trains run on a bottom-contact {{750 V DC|conductor=y}}, or an overhead wire (in maintenance areas where a third rail would not be safe).

== Incidents ==
{{More citations needed section|date=September 2022}}
In its 45 years of operations, there have never been any very grave accidents, however, there have been various incidents, either during construction or operation. Accidents are investigated by the Railway Investigation Authority (Agenția de Investigare Feroviară Română (AGIFER)).

*1983: Due to works on M2, the Piața Unirii 1 station was flooded by the [[Dâmbovița (river)|Dâmbovița]].
*April–May 1986: Whilst digging for a connection service tunnel for the M1-M2 lines, the foundations and altar of the [[Slobozia Church]] were cracked, leading to the subsequent closure of the construction site of the tunnel, which was filled with sand. Thus, trains for the M2 were disconnected from the rest of the network up to 1987 (trains were sent through the Bucharest Freight Railway Bypass), when another link tunnel was created at Piața Victoriei.
*1 May 1987: During reconstruction work at Piața Unirii, the Dâmbovița was breached again, this time flooding both stations and forcing train circulation to cease for the next 5 days as a result. The flooding took place during a heavy rainstorm and during work on the [[Unirii Underpass]] (which was opened on 6 June 1987, after a record 34 days of work), when an excavator damaged a collecting canal of the Dâmbovița, flooding the underpass construction site, and subsequently, the M1 station. The M2 metro station was flooded due to an improperly sealed tube, designed for electric installations. At its peak, the flooding was 30 centimeters over the platforms, but further damages to the electrical transformers were avoided.
*2 May 1987: During recovery from the flooding at Piața Unirii the previous day, the tunnel between Timpuri Noi and Mihai Bravu was found fully submerged by the Dâmbovița, possibly in relation to the previous incident. Signalling and other electrical cables were damaged, which further prolonged the repair efforts for the previous incident.
*4 March 1996: The metro workers began a strike, demanding a 48% pay increase to offset inflation and better working conditions. It continued for at least 2 days, and was condemned by the Văcăroiu government as illegal.<ref>{{Cite news|url=https://www.rferl.org/a/1080164.html|title=Bucharest Metro Workers Continue Strike|newspaper=Radio Free Europe/Radio Liberty |date=9 April 2008 }}</ref>
*17 November 2010: An IVA train derailed between Timpuri Noi and Piața Unirii.
*14 January 2015: Due to a broken pipe, a fire started out at Tineretului station, leading to its closure for the rest of the day.
*14 June 2016: Piața Victoriei was closed after huge amounts of smoke originated from the third rail.
*20 January 2017: A fire, originating from electrical contactors, led to the evacuation of the Universitate station, subsequently leading to the closure of one of the tracks towards Piața Unirii.
*16 August 2018: A train in Piața Unirii had to be evacuated, after someone began pepper-spraying the consist stopped in the station.
*26 January 2019: A newly purchased CAF unit crashed in the Berceni depot. The train, which was stabled outside, was being shunted into the depot to prevent icing, however, due to software failure, it could not stop on time and crashed past the buffers. It is likely that the train could be scrapped since there is no way to remove it.
*26 March 2021: A sudden strike, launched by the union of the metro employees began at 5 AM, effectively blocking the circulation of all trains. The dispute is related to the activity of commercial spaces within metro stations.<ref>{{Cite web|url=https://clubferoviar.ro/breaking-greva-spontana-la-metrou/|title = Grevă spontană la metrou.

Aside from these incidents, there have been other disruptions due to suicides at the metro. A recent one on 25 June 2019, led to the disruption of metro traffic at rush hour between Piața Unirii and Eroilor (the suicide took place at Izvor). Aside from that, in 2017, one woman was arrested for pushing a person in front of a train. These incidents led to criticism of METROREX, and suggestions to install [[platform screen doors]] or to increase security. Additionally, [[railfan]]s reported harassment from security guards, being told "not to photograph in the stations".

Currently, the Bucharest Metro does not use platform screen doors. Debates about the opportunity of using platform screen doors have been going on for years, and testing of such doors has been taking place at [[Berceni metro station]],<ref>{{cite web | url=https://economedia.ro/proiect-pilot-la-metrou-metrorex-monteaza-porti-de-protectie-anti-suicid-pe-peronul-statiei-berceni.html | title=VIDEO Proiect pilot la Metrou : Metrorex montează porți de protecție ,,anti-suicid" pe peronul stației Berceni | date=9 July 2022 }}</ref> but in 2024 authorities stated that it is uncertain whether platform screen doors will be installed, given concerns about financing and [[costs and benefits]].<ref>{{cite web |last=Andone |first=Anemona |date=3 May 2024 |title=Porți de protecție la metrou: Ce se mai întâmplă cu proiectul – pilot din stația Berceni |url=https://www.economica.net/porti-de-protectie-la-metrou_744294.html |website=Economica.net |language=ro}}</ref> Since all the stations of Bucharest Metro were inaugurated without having platform screen doors, installing such doors would require [[retrofitting]], namely the process of installing platform screen doors on a system that was not initially designed to accommodate such doors, which may be complex and difficult,<ref>{{cite web | url=https://www.capital.ro/de-ce-nu-vom-avea-vreodata-sisteme-de-protectie-de-la-metrou.html | title=De ce nu vom avea vreodată sisteme de protecţie la metrou | date=May 2018 }}</ref> especially if the [[Platform_screen_doors#Types|type]] installed were to be full-height doors (rather than half-height doors or rope-doors which are more common in retrofitting, but have limited benefits compared to full height doors).

== Miscellaneous ==
Bucharest Metro was the only one in the world that operated with passengers during testing.<ref>{{Cite web|url=http://www.bucurestiivechisinoi.ro/2014/11/metroul-din-bucuresti-singurul-din-lume-care-a-functionat-cu-calatori-in-perioada-de-probe/|title=Metroul din București, singurul din lume care a funcționat cu călători în perioada de probe |work=Bucurestii Vechi si Noi|date=24 November 2014|language=ro-RO|access-date=2018-07-07}}</ref>

In the 1980s, the speed of building the network (4 kilometers / year) placed the Bucharest Metro on the second place in the world, after [[Mexico City Metro]].<ref name="auto2"/>

The shortest distance between two adjacent stations is between [[Gara de Nord metro station|Gara de Nord 2]] [[Bucharest Metro Line M4|(M4)]] and [[Basarab metro station|Basarab 2]] [[Bucharest Metro Line M4|(M4)]] and is 430 meters.
