The Bucharest Metro (Romanian: Metroul București) is an underground rapid transit system that serves Bucharest, the capital of Romania. It first opened for service on 16 November 1979. The network is run by Metrorex. One of two parts of the larger Bucharest public transport network, Metrorex has an average of approximately 720,000 passenger trips per weekday (as of 2018), compared to the 1,180,000 daily riders on Bucharest's STB transit system. In total, the Metrorex system is 77.53 kilometres (48.2 mi) long and has 63 stations.
The earliest plans for a Bucharest Metro were drafted in the late 1930s, alongside the general plans for urban modernization of the city. The outbreak of World War II, followed by periods of political tensions culminating with the installation of communism, put an end to the plans.
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 plan and the construction on the new metro system started on 20 September 1975.
The network was not built in the same style as other Eastern European systems. Firstly, the design of the stations on the initial lines was simple, clean-cut modern, without excessive additions such as mosaics, awkward lighting sources or excessive 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. Each station usually followed a colour theme (generally white – in Unirii 2, Victoriei 1, Lujerului; but also light blue – in Obor, Universitate, and Gara de Nord; orange – in Tineretului; green - in 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. Bucharest being one of the largest cities in the region, the network is larger than those of Prague or Budapest. When the planned new line-extensions are finished, they will increase the system length to more than 100 km, with about 80 stations.
The first line, M1, opened on 19 November 1979, running from Semănătoarea (now Petrache Poenaru) to Timpuri Noi. It had a length of 8.1 kilometres (5.0 mi) with 6 stations. Following this, more lines and several extensions were opened:
- 28 December 1981: M1 Timpuri Noi – Republica; 9.2 kilometres (5.7 mi), 6 stations
- 19 August 1983: M1 (now M3) Branch line Eroilor – Industriilor (now Preciziei) ; 8.2 kilometres (5.1 mi), 4 stations (Gorjului added later)
- 22 December 1984: M1 Semănătoarea (Petrache Poenaru) – Crângași; 0.97 kilometres (0.60 mi), 1 station
- 24 January 1986: M2 Piața Unirii – Depoul IMGB (now Berceni) ; 9.96 kilometres (6.19 mi), 6 stations (Tineretului and Constantin Brâncoveanu added later)
- 6 April 1986: M2 Tineretului; 1 infill station
- 24 October 1987: M2 Piața Unirii – Pipera; 8.72 kilometres (5.42 mi), 5 stations (Piața Romană added later)
- 24 December 1987: M1 Crângași – Gara de Nord 1; 2.83 kilometres (1.76 mi), 1 station (Basarab added later)
- 28 November 1988: M2 Piața Romană; 1 infill station
- 5 December 1988: M2 Constantin Brâncoveanu; 1 infill station
- 17 August 1989: M3 (now M1) Gara de Nord 1 – Dristor 2; 7.8 kilometres (4.8 mi), 6 stations
- May 1991: M1 Republica – Pantelimon; 1.43 kilometres (0.89 mi), 1 station (single track, operational on a special schedule)
- 26 August 1992: M1 Basarab; 1 infill station
- 31 August 1994: M3 Gorjului; 1 infill station (westbound platform only; eastbound platform opened in 1998)
- 1 March 2000: M4 Gara de Nord 2 – 1 Mai; 3.6 kilometres (2.2 mi), 4 stations
- 20 November 2008: M3 branch Nicolae Grigorescu 2 – Linia de Centură (now Anghel Saligny), 4.75 kilometres (2.95 mi), 4 stations
- 1 July 2011: M4 1 Mai – Parc Bazilescu, 2.62 kilometres (1.63 mi), 2 stations
- 31 March 2017: M4 Parc Bazilescu – Străulești, 1.89 kilometres (1.17 mi), 2 stations
- 15 September 2020: M5 Raul Doamnei / Valea Ialomitei – Eroilor 2, 6.87 kilometres (4.27 mi), 10 stations
Lines M1 and M3 have been sharing the section between Eroilor and Nicolae Grigorescu.
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. The largest one, 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. 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 NetworkEdit
Starting in 2018, the entire network runs underground, except for a short stretch between Dimitrie Leonida and Berceni stations on the southern end of the M2 line. The network is served by six depots, two being located above ground (IMGB and Industriilor) and four underground (Ciurel, Străulești, Pantelimon and Valea Ialomitei) and smaller additional works at Gara de Nord and Eroilor 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). The latter connection however is unused and mothballed. The metro network and the national rail network share the same track gauge (1,435 mm / 4 ft 8 1⁄2 in) and loading gauge but not the same electrification system (the metro uses 750 V DC whereas the Romanian Railways use 25,000 V 50 Hz AC) making it possible for new metro cars to be transported cross country as unpowered railway cars.
There are 5 metro lines in operation, and another 1 in the planning phase:

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) and operation (Automatic train operation) of the new Bombardier Movia trains.
The system uses an IPU (Interlocking processing unit), TI21-M track circuits and EbiScreen workstations. Signals have been kept only in areas where points are present, but only use a white light, 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 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 signals have been removed.
Line 5 will use Alstom's Urbalis 400 Communications-based train control system.
Hours of operationEdit
At rush hour, trains run at 4–6-minute intervals on lines 1 and 3, 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, 7-9 minute intervals on line 2 and 10-minute intervals on line 4.
Fares and ticketsEdit
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. Like the STB, the metro can get crowded during morning and evening rush hours. The network uses magnetic stripe cards, that are not valid for use on trams, buses or trolleys . Payment by contactless credit cards is available directly at the turnstiles. One tap will take 2.5 RON, the equivalent of one trip. For multiple validations with the same card, tap the plus button.
Magnetic stripe cardsEdit
Older style metro cards can be purchased at any metro station, except discounted passes, which can only be purchased at a limited number of stations. Prices :
- 1 trip Integrated Metro and STB (Bus, tram, trolleybus) ticket; valid for 60 minutes after first use - 5 RON - Not to be used on express or regional bus lines.
- 10 trip Integrated Metro and STB (Bus, tram, trolleybus) ticket; valid for 60 minutes for each trip - 34 RON - Not to be used on express or regional bus lines.
- 1-trip card – 2.50 lei
- 2-trip card – 5 lei (€1.13)
- 1-day card – 8 lei (€1.80)
- 10-trip card – 20 lei (€4.52)
- Unlimited weekly pass (full price) – 25 lei (€5.65)
- Unlimited monthly pass (full price) – 70 lei (€15.82)
- Unlimited student monthly pass (available for students in Romanian universities) – 35 lei (€7.91)
- Free for senior citizens over 70 years of age
Older-style metro cards are not linked with personal data or usage data in a central database and thus they guarantee anonymity of the travel. Because of that, however, if a metro card is lost or damaged, the traveler cannot be reimbursed for the unused trips.
- M2 Line southbound extension (1.6 km (1.0 mi)):
- M2 Line: a further northbound extension of 1.6 km (1.0 mi) and two more stations from Pipera;
- M4 Line extension: between Gara de Nord, through Soseaua Giurgiului and ending at Gara Progresul at Bucharest' southern limit , this section is in a very early planning phase;
- M5 Line: a further extension of 9.2 km (5.7 mi) to Pantelimon is approved;
- M6 Line: between Gara de Nord and Henri Coandă International Airport.
Metrorex is also planning the following new lines, routes and stations:
- Line M7; it is supposed to run 25 kilometres (16 mi) from Bragadiru to Voluntari.
- Line M8, the south half ring. Its route has not been fully planned yet, but it will run through Piața Sudului and end at Crângași and Dristor stations.
- An extension of the Line M3 is also planned for 2030.
- Two more stations are planned and may be constructed on existing lines, both on M1. However, given the complexity of work required, and the limited benefits these stations would have it is unlikely that construction will begin in the near future:
- Astra IVA – 31 trainsets (186 cars), built between 1976 and 1992, of which 15 trainsets (90 cars) modernised by Metrorex and Alstom Transport România in 2011-2013, used on M3 and M4;
- Bombardier Movia 346 – 44 trainsets (264 cars), built between 2002 and 2008, used on M1, M2, M3 and M5;
- CAF - 24 trainsets (144 cars), built between 2013 and 2016, used on M2.
|Vehicle||Type and description||Interior|
|The Romanian designed Astra IVA trains, built in 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 and M4.|
|The Bombardier Movia 346 trains are made up of six permanently connected cars, forming an open corridor for the entire length of the train (2'2'+Bo'Bo'+Bo'Bo'+Bo'Bo'+Bo'Bo'+2'2' formation). Bombardier trains are used on all lines, except line M4.|
|In November 2011, Metrorex signed a €97 million contract with CAF for 16 metro trains (96 cars), with options for a further 8 sets (48 cars). The 114m-long six-car trains will be assembled in Romania. They each accommodate up to 1,200 passengers and are made up of four powered and two trailer vehicles. As of November 2014, all trains have been delivered and all 16 of them entered in service. As the CAF trains enter service, all of the Bombardier stock will be moved for use on line M3, according to Metrorex's plans to replace all of the old Astra IVA stock on the entire network.
In November 2014, Metrorex signed an additional €47 million contract with CAF for 8 metro trains. As of 2018, 24 CAF trains are in use, exclusively on line M2.
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 750 V DC third rail, or an overhead wire (in maintenance areas where a third rail would not be safe). Maximum speed on the system is 80 km/h (50 mph), although plans are to increase it to 100 km/h (60 mph) on M5, a new line that opened its first phase on the 15th September 2020.  New trains from Alstom (Metropolis) have been ordered and are due to arrive in 2023.

In its more than 40 years of operations, there never have been 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.
- 1986, April or May: 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.
- 1987, 1 May: 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.
- 1987, 2 May: 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.
- 2010, 17 November: An IVA train derailed between Timpuri Noi and Piața Unirii.
- 2015, 14 January: Due to a broken pipe, a fire started out at Tineretului station, leading to its closure for the rest of the day.
- 2016, 14 June: Piața Victoriei was closed after huge amounts of smoke originated from the third rail.
- 2017, 20 January: 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.
- 2018, 16 August: A train in Piața Unirii had to be evacuated, after someone began pepper-spraying the consist stopped in the station.
- 2019, 26 January: 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.
Aside from these incidents, there have been other disruptions, especially in the last 3 years, due to suicides at the metro. A recent one on 25 June 2019, lead 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, railfans reported harassment from security guards, being told "not to photograph in the stations", despite there being no official rule prohibiting photography in the metro network.
Bucharest Metro was the only one in the world that operated with passengers during testing.
