138-525: A pylon station . The first deep column station in the world is Mayakovskaya , opened in 1938 in Moscow. One variety of column station is the "column-wall station". In such stations, some of the spaces between the columns are replaced with walls. In this way, the resistance to earth pressure is improved in difficult ground environments. Examples of such stations in Moscow are Krestyanskaya Zastava and Dubrovka . In Saint Petersburg , Komendantsky Prospekt
184-564: A disabled or troubled train. A subway station may provide additional facilities, such as toilets , kiosks and amenities for staff and security services, such as Transit police . Some metro stations are interchanges , serving to transfer passengers between lines or transport systems. The platforms may be multi-level. Transfer stations handle more passengers than regular stations, with additional connecting tunnels and larger concourses to reduce walking times and manage crowd flows. In some stations, especially where trains are fully automated ,
230-497: A preexisting railway land corridor is re-purposed for rapid transit. At street level the logo of the metro company marks the entrances/exits of the station. Usually, signage shows the name of the station and describes the facilities of the station and the system it serves. Often there are several entrances for one station, saving pedestrians from needing to cross a street and reducing crowding. A metro station typically provides ticket vending and ticket validating systems. The station
276-451: A radius of 201.9 m (662 ft)—both are the tightest of the overpass. According to the Metro union leader, the trains wear out the rails and wheels when there are sharp curves and cause them to clatter. This damage structures such as girders and columns. After the 2017 earthquake, a girder in the section was reinforced with a diagonally-reinforced beam because a seismic top on Column 41
322-432: A station may be elevated above a road, or at ground level depending on the level of the train tracks. The physical, visual and economic impact of the station and its operations will be greater. Planners will often take metro lines or parts of lines at or above ground where urban density decreases, extending the system further for less cost. Metros are most commonly used in urban cities, with great populations. Alternatively,
368-740: A whole is usually called a "metro" or "subway". A station provides a means for passengers to purchase tickets , board trains, and evacuate the system in the case of an emergency. In the United Kingdom, they are known as underground stations , most commonly used in reference to the London Underground . The location of a metro station is carefully planned to provide easy access to important urban facilities such as roads, commercial centres, major buildings and other transport nodes . Most stations are located underground, with entrances/exits leading up to ground or street level. The bulk of
414-412: Is a bicycle parking station . In 2019, the station had an average daily ridership of 22,491 passengers, making it the 5th busiest station on the line. Since it was opened, Nopalera metro station has had multiple incidents, including a 20-month closure in 2014 due to structural faults found in the elevated section of the line, a closure caused by the 19 September 2017 earthquake that affected
460-416: Is a type of subway station consisting of a central hall with two side halls connected by ring-like passages between a row of columns. Depending on the type of station, the rings transmit load to the columns either by "wedged arches" or through Purlins , forming a "column-purlin complex". The fundamental advantage of the column station is the significantly greater connection between the halls, compared with
506-410: Is an example. The pylon station is a type of deep underground subway station. The basic distinguishing characteristic of the pylon station is the manner of division of the central hall from the station tunnels The pylon station consists of three separate halls, separated from each other by a row of pylons with passages between them. The independence of the halls allows the architectural form of

#1732797660103552-493: Is at the expense of character. Metro stations usually feature prominent poster and video advertising, especially at locations where people are waiting, producing an alternative revenue stream for the operator . The shallow column station is a type of construction of subway stations, with the distinguishing feature being an abundance of supplementary supports for the underground cavity. Most designs employ metal columns or concrete and steel columns arranged in lines parallel to
598-787: Is decorated with tiles spelling the Déclaration des Droits de l'Homme et du Citoyen . Every metro station in Valencia , Spain has a different sculpture on the ticket-hall level.

Each of the original four stations in the Olympic Green on Line 8 of the Beijing Subway are decorated in Olympic styles, while
644-422: Is divided into an unpaid zone connected to the street, and a paid zone connected to the train platforms. The ticket barrier allows passengers with valid tickets to pass between these zones. The barrier may be operated by staff or more typically with automated turnstiles or gates that open when a transit pass is scanned or detected. Some metro systems dispense with paid zones and validate tickets with staff in
690-550: Is famous for its Art Nouveau station entrances; while the Athens Metro is known for its display of archeological relics found during construction. However, it is not always the case that metro designers strive to make all stations artistically unique. Sir Norman Foster 's new system in Bilbao , Spain uses the same modern architecture at every station to make navigation easier for the passenger, though some may argue that this
736-658: Is only one vault (hence the name). The first single-vault stations were built in Leningrad in 1975: Politekhnicheskaya and Ploshchad Muzhestva . Not long after, the first two-level single-vault transfer stations were opened in Washington DC in 1976: L'Enfant Plaza , Metro Center and Gallery Place . In the Moscow Metro there is only one deep underground single-vault station, Timiryazevskaya , in addition to several single-vault stations at shallow depth. In

Atlalilco metro station Atlalilco is a station along Line 8 and Line 12 of
1242-444: The central and side halls to be differentiated. This is especially characteristic in the non-metro Jerusalem–Yitzhak Navon railway station , constructed as a pylon station due to its 80-meter depth, where the platform halls are built to superficially resemble an outdoor train station. Building stations of the pylon type is preferable in difficult geological situations, as such a station is better able to oppose earth pressure. However,
1288-597: The downtown stations are decorated traditionally with elements of Chinese culture. On the Tyne and Wear Metro , the station at Newcastle United 's home ground St James' Park is decorated in the clubs famous black and white stripes. Each station of the Red Line and Purple Line subway in Los Angeles was built with different artwork and decorating schemes, such as murals, tile artwork and sculptural benches. Every station of
1334-452: The entire platform is screened from the track by a wall, typically of glass, with automatic platform-edge doors (PEDs). These open, like elevator doors, only when a train is stopped, and thus eliminate the hazard that a passenger will accidentally fall (or deliberately jump ) onto the tracks and be run over or electrocuted . Control over ventilation of the platform is also improved, allowing it to be heated or cooled without having to do
1380-453: The former USSR there is currently only one such station: Arsenalna in Kyiv . In Jerusalem, two planned underground heavy rail stations, Jerusalem–Central and Jerusalem–Khan , will be built this way. In Moscow, there were such stations, but they have since been rebuilt: Lubyanka and Chistiye Prudy are now ordinary pylon stations, and Paveletskaya-Radialnaya is now a column station. In
1426-453: The interstation tunnel is about 800 m (2,625 ft) long because the original plan for a transfer station to be named Axomulco was canceled. The interstation tunnel runs underground through Calzada Ermita Iztapalapa and Avenida Tlahuac, with an additional access to the station at the intersection of both avenues. It is the only station that has mechanical bands to assist in the interstation walk. This Mexico metro station article

1472-409: The limited number of narrow passages limits the throughput between the halls. The pylon station was the earliest type of deep underground station. One variation is the so-called London-style station. In such stations the central hall is reduced to the size of an anteroom, leading to the inclined walkway or elevators. In some cases the anteroom is also the base of the escalators. In the countries of
1518-461: The long axis of the station. Stations can be double-span with a single row of columns, triple-span with two rows of columns, or multi-span. The typical shallow column station in Russia is triple-span, assembled from concrete and steel, and is from 102 to 164 metres in length with a column spacing of 4–6 m. Along with the typical stations, there are also specially built stations. For example, one of

Since 2010, the Superior Auditor of the Federation has audited Line 12 several times and has reported several faults, like cracks and detachments along the line, including some at the Nopalera–Zapotitlán–Tlaltenco overpass. From 12 March 2014 to 29 November 2015, Nopalera was closed due to technical and structural faults in
1610-481: The same for the tunnels. The doors add cost and complexity to the system, and trains may have to approach the station more slowly so they can stop in accurate alignment with them. Metro stations, more so than railway and bus stations, often have a characteristic artistic design that can identify each stop. Some have sculptures or frescoes. For example, London's Baker Street station is adorned with tiles depicting Sherlock Holmes . The tunnel for Paris' Concorde station
1656-792: The spans may be replaced with a monolithic vault (as in the Moskovskaya station of the Samara Metro or Sibirskaya of the Novosibirsk Metro ). In some cases, one of the rows of columns may be replaced with a load-bearing wall. Such a dual hall, one-span station, Kashirskaya , was constructed to provide a convenient cross-platform transfer. Recently, stations have appeared with monolithic concrete and steel instead of assembled pieces, as Ploshchad Tukaya in Kazan . The typical shallow column station has two vestibules at both ends of
