Rapid transit or mass rapid transit ( MRT ) or heavy rail , commonly referred to as metro , is a type of high-capacity public transport that is generally built in urban areas . A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway , tube , metro or underground . They are sometimes grade-separated on elevated railways , in which case some are referred to as el trains – short for "elevated" – or skytrains . Rapid transit systems are railways , usually electric , that unlike buses or trams operate on an exclusive right-of-way , which cannot be accessed by pedestrians or other vehicles.
150-646: The Hudson Terminal was a rapid transit station and office-tower complex in the Radio Row neighborhood of Lower Manhattan in New York City . Opened during 1908 and 1909, it was composed of a terminal station for the Hudson & Manhattan Railroad (H&M), as well as two 22-story office skyscrapers and three basement stories. The complex occupied much of a two-block site bounded by Greenwich , Cortlandt , Church , and Fulton Streets , which later became
300-425: A body of water), which are potential congestion sites but also offer an opportunity for transfers between lines. Ring lines provide good coverage, connect between the radial lines and serve tangential trips that would otherwise need to cross the typically congested core of the network. A rough grid pattern can offer a wide variety of routes while still maintaining reasonable speed and frequency of service. A study of
450-402: A cable-hauled line using stationary steam engines . As of 2021 , China has the largest number of rapid transit systems in the world – 40 in number, running on over 4,500 km (2,800 mi) of track – and was responsible for most of the world's rapid-transit expansion in the 2010s. The world's longest single-operator rapid transit system by route length
600-454: A code for its stations. Unlike that of Singapore's MRT, it is mostly numbers. Based on the line number, for example Sinyongsan station, is coded as station 429. Being on Line 4, the first number of the station code is 4. The last two numbers are the station number on that line. Interchange stations can have multiple codes. Like City Hall station in Seoul which is served by Line 1 and Line 2. It has
750-651: A code of 132 and 201 respectively. The Line 2 is a circle line and the first stop is City Hall, therefore, City Hall has the station code of 201. For lines without a number like Bundang line it will have an alphanumeric code. Lines without a number that are operated by KORAIL will start with the letter 'K'. With widespread use of the Internet and cell phones globally, transit operators now use these technologies to present information to their users. In addition to online maps and timetables, some transit operators now offer real-time information which allows passengers to know when
900-714: A combined 70,000 square feet (6,500 m). According to the Engineering Record , the Fulton Building occupied a lot measuring about 156 by 154 feet (48 by 47 m), while the Cortlandt Building occupied a lot measuring about 213 by 170 feet (65 by 52 m). However, the New-York Tribune gave slightly different measurements of 155.9 by 179.8 feet (48 by 55 m) for the Fulton Building and 214.35 by 186.3 feet (65 by 57 m) for
1050-493: A combined ten thousand tenants across 4,000 offices. At ground level, the buildings contained glass-enclosed shopping arcades that were "much larger than the famous European arcades". There were three stories of basements beneath the office buildings. The first basement level was a shopping and waiting concourse directly below the street. The second basement level contained the H&M platforms. The third and lowest level contained
1200-583: A conventional track is often provided in case of flat tires and for switching . There are also some rubber-tired systems that use a central guide rail , such as the Sapporo Municipal Subway and the NeoVal system in Rennes , France. Advocates of this system note that it is much quieter than conventional steel-wheeled trains, and allows for greater inclines given the increased traction of
1350-436: A day. This included 17 passenger elevators and a freight elevator in the Fulton Building, and 21 elevators in the Cortlandt Building. Of the 39 elevators in the buildings, 22 ran nonstop from the lobby to the eleventh floor while the remainder served every floor below the eleventh. Three of the elevators continued to the underground concourse, although the elevators did not descend to the concourse except during emergencies. With
1500-405: A dedicated right-of-way are typically used only outside dense areas, since they create a physical barrier in the urban fabric that hinders the flow of people and vehicles across their path and have a larger physical footprint. This method of construction is the cheapest as long as land values are low. It is often used for new systems in areas that are planned to fill up with buildings after the line
1650-421: A falling elevator in 1923, and a woman was killed two years later after being trapped in an elevator. Phillips Petroleum Company executive Taylor S. Gay was also shot and killed in the terminal in 1962. There were several incidents in the H&M station as well. In 1937, a 5-car H&M train crashed into a wall, injuring 33 passengers. Twenty-six people were injured in a 1962 crash between two H&M trains at

A transit system is expected to serve an area of land with a set of lines , which consist of shapes summarized as "I", "L", "U", "S", and "O" shapes or loops. Geographical barriers may cause chokepoints where transit lines must converge (for example, to cross
2100-652: A large part of the network, for example, in outer suburbs, runs at ground level. In most of Britain , a subway is a pedestrian underpass . The terms Underground and Tube are used for the London Underground . The North East England Tyne and Wear Metro , mostly overground, is known as the Metro . In Scotland , the Glasgow Subway underground rapid transit system is known as the Subway . In Ireland ,
2250-452: A line is obtained by multiplying the car capacity, the train length, and the service frequency . Heavy rapid transit trains might have six to twelve cars, while lighter systems may use four or fewer. Cars have a capacity of 100 to 150 passengers, varying with the seated to standing ratio – more standing gives higher capacity. The minimum time interval between trains is shorter for rapid transit than for mainline railways owing to
2400-572: A live load of 105 psf (5.0 kPa), for 200 psf (9.6 kPa) total, while the Cortlandt Building could carry a dead load of 85 psf (4.1 kPa) and a live load of 75 psf (3.6 kPa), for 160 psf (7.7 kPa) total. The columns were allowed to take a minimum stress of 11,500 psi (79,000 kPa) and a maximum stress of 13,000 psi (90,000 kPa). The floors were generally made of reinforced concrete slabs placed between I-beams , with cinder concrete fill and yellow-pine finish. Terracotta tile, brick, and concrete

The Italian cities of Catania , Genoa , Milan , Naples , Rome and Turin also have metro lines. In Germany and Austria they rapid transit is known as U-Bahn , which are often supported by S-Bahn systems. In Germany, U-Bahn systems exist in Berlin , Hamburg , Munich and Nuremberg , while in Austria such
2850-443: A new City Hall. The first prize of $ 350 was awarded to Joseph-François Mangin and John McComb Jr. Mangin studied architecture in his native France before becoming a New York City surveyor in 1795 and publishing an official map of the city in 1803 that was largely discredited for its inaccuracies. Mangin later served as the architect of the landmarked St. Patrick's Old Cathedral on Mulberry Street. McComb, whose father had worked on
3000-679: A new PATH station to replace the Hudson Terminal station, as well as a public plaza to replace the buildings. Groundbreaking on the World Trade Center took place in 1966, and as with the Hudson Terminal buildings, a slurry wall to keep out water from the Hudson River. During excavation of the site and construction of the towers, the Downtown Tubes remained in service, with excavations continuing around and below
3150-518: A pedestrian bridge over the street on the third story of each building. A bridge connecting the buildings' 17th floors was approved and built in 1913, soon after the complex had opened. As completed, the buildings used 16.3 million bricks, 13,000 lighting fixtures, 15,200 doors, 5,000 windows, and 4,500 short tons (4,000 long tons; 4,100 t) of terracotta, as well as 1,300,000 square feet (120,000 m) of partitions and 1,100,000 cubic feet (31,000 m) of concrete floor arches.

New York City Hall New York City Hall is the seat of New York City government , located at the center of City Hall Park in the Civic Center area of Lower Manhattan , between Broadway , Park Row , and Chambers Street . Constructed from 1803 to 1812, the building is the oldest city hall in the United States that still houses its original governmental functions. The building houses
3450-565: A specialized transit police may be established. These security measures are normally integrated with measures to protect revenue by checking that passengers are not travelling without paying. Some subway systems, such as the Beijing Subway , which is ranked by Worldwide Rapid Transit Data as the "World's Safest Rapid Transit Network" in 2015, incorporates airport-style security checkpoints at every station. Rapid transit systems have been subject to terrorism with many casualties, such as

There are no U-Bahn systems in the German-speaking part of Switzerland, but the city of Lausanne has its own, small metro system. In Zurich, Switzerland's largest city, a project for a U-Bahn network was stopped by a referendum in the 1970s and instead its S-Bahn system
3750-631: A third of the total space in the buildings. The top floors of each building had private dining clubs: the Downtown Millionaires Club atop the Cortlandt Building and the Machinery Club atop the Fulton Building. With the exception of a brief period between 1922 and 1923, the terminal's post office operated until the United States Postal Annex at 90 Church Street opened two blocks north in 1937. Space in

Rapid transit systems such as the Washington Metrorail , Los Angeles Metro Rail , the Miami Metrorail , and the Montreal Metro are generally called the Metro . In Philadelphia , the term "El" is used for the Market–Frankford Line which runs mostly on an elevated track, while the term "subway" applies to the Broad Street Line which is almost entirely underground. Chicago 's commuter rail system that serves
4650-608: Is a single corporate image for the entire transit authority, but the rapid transit uses its own logo that fits into the profile. A transit map is a topological map or schematic diagram used to show the routes and stations in a public transport system. The main components are color-coded lines to indicate each line or service, with named icons to indicate stations. Maps may show only rapid transit or also include other modes of public transport. Transit maps can be found in transit vehicles, on platforms , elsewhere in stations, and in printed timetables . Maps help users understand

4800-506: Is built. Most rapid transit trains are electric multiple units with lengths from three to over ten cars. Crew sizes have decreased throughout history, with some modern systems now running completely unstaffed trains. Other trains continue to have drivers, even if their only role in normal operation is to open and close the doors of the trains at stations. Power is commonly delivered by a third rail or by overhead wires . The whole London Underground network uses fourth rail and others use

If this extension had been built, it would have tripled the maximum number of trains that could go into the Hudson Terminal station. The sections of tunnel around the Hudson Terminal station were taken out of regular service when the World Trade Center station was built about 450 feet (140 m) to the west. The World Trade Center station could fit ten-car trains, and sat underneath Greenwich Street, which
5550-555: Is referred to simply as "the subway", despite 40% of the system running above ground. The term "L" or "El" is not used for elevated lines in general as the lines in the system are already designated with letters and numbers. The "L" train or L (New York City Subway service) refers specifically to the 14th Street–Canarsie Local line, and not other elevated trains. Similarly, the Toronto Subway is referred to as "the subway", with some of its system also running above ground. These are

Located directly under City Hall Park is the former City Hall subway station, the original southern terminal of the first service of the New York City Subway built by the Interborough Rapid Transit Company (IRT). Opened on October 27, 1904, this station beneath the public area in front of City Hall
8100-480: The World Trade Center site . The railroad terminal contained five tracks and six platforms serving H&M trains to and from New Jersey ; these trains traveled via the Downtown Hudson Tubes , under the Hudson River , to the west. The two 22-story office skyscrapers above the terminal, the Fulton Building to the north and the Cortlandt Building to the south, were designed by architect James Hollis Wells of
8250-450: The deep tube lines . Historically, rapid transit trains used ceiling fans and openable windows to provide fresh air and piston-effect wind cooling to riders. From the 1950s to the 1990s (and in most of Europe until the 2000s), many rapid transit trains from that era were also fitted with forced-air ventilation systems in carriage ceiling units for passenger comfort. Early rapid transit rolling stock fitted with air conditioning , such as
8400-409: The linear motor for propulsion. Some urban rail lines are built to a loading gauge as large as that of main-line railways ; others are built to a smaller one and have tunnels that restrict the size and sometimes the shape of the train compartments. One example is most of the London Underground , which has acquired the informal term "tube train" due to the cylindrical shape of the trains used on

Dey Street was carried above the mezzanine via a series of plate girders and I-beams, which formed a "skeleton platform" measuring about 180 ft (55 m) long by 27 ft (8.2 m) wide. The structure carrying Dey Street could accommodate loads of up to 1,400 psf (67 kPa). In total, the substructure included 11,000 cubic yards (8,400 m) of concrete and 6,267 short tons (5,596 long tons; 5,685 t) of structural steel. During

The station ran perpendicularly to both of the Downtown Tubes, and at either end of the station, there were sharp curves to and from each tube, with track radii of 90 feet (27 m). The eastbound tunnel ran under Cortlandt Street and the westbound tunnel ran two blocks north under Fulton Street. The station had been built with five tracks because, at
9900-534: The IND had also planned for a passageway between its Chambers Street station and the H&M's terminal in the original plan for the Eighth Avenue Line, a direct passageway to the Chambers Street station was not opened until 1949. Hudson Terminal included two 22-story Romanesque-style office skyscrapers above the H&M station. The buildings were designed by architect James Hollis Wells, of
10050-524: The baggage room, electrical substation , and an engine and boiler room for the substation. The depth of the H&M platforms was mandated by the city's Rapid Transit Railroad Commission. To provide space for potential north–south subway lines in Lower Manhattan, the roof of any "tunnel railroad" in the area had to be at least 20 feet (6.1 m) below any north–south street. Four cement ramps, two each from Cortlandt and Fulton Streets, descended to
10200-478: The beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant. Experiments with pneumatic railways failed in their extended adoption by cities. In 1890, the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Prior to opening, the line was to be called the "City and South London Subway", thus introducing

As a result of the security breach, then-Mayor Michael Bloomberg revised security policy to require that everyone entering the building pass through metal detectors without exception. In 2008, work began on a restoration of the building, after a century without a major renovation. The construction included structural enhancements, upgrades to building services, as well as in-depth restoration of much of
10500-803: The buildings started in December 1905. The Hudson Companies acquired most of the two blocks bounded by Greenwich Street to the west, Cortlandt Street to the south, Church Street to the east, and Fulton Street to the north. Some low-rise buildings on Cortlandt Street were acquired to protect the views from the Hudson Terminal buildings. One landowner—the Wendel family, which owned a myriad of Manhattan properties—refused to sell their property, assessed at $ 75,000 (equivalent to $ 1,972,097 in 2023), and filed an unsuccessful lawsuit against H&M in which they spent $ 20,000 (equivalent to $ 525,892 in 2023) on legal fees. By May 1906, H&M had taken title to most of
10650-421: The buildings was also occupied by agencies of the United States federal government in the 1960s. H&M ridership declined substantially from a high of 113 million riders in 1927 to 26 million in 1958, after new automobile tunnels and bridges opened across the Hudson River. The H&M had gone bankrupt in 1954. The state of New Jersey wanted the Port Authority of New York and New Jersey to take over
10800-691: The buildings were demolished in 1972, the last remnants of the station were removed in the 2000s as part of the development of the new World Trade Center following the September 11 attacks in 2001. In January 1905, the Hudson Companies was incorporated for the purpose of completing the Uptown Hudson Tubes , a tunnel between Jersey City, New Jersey , and Midtown Manhattan , New York City, that had been under construction intermittently since 1874. The Hudson Companies would also build
10950-499: The buildings were many miles of plumbing, steam piping, wood base, picture molding, conduits, and electrical wiring. The superstructure of the Hudson Terminal buildings required over 28,000 short tons (25,000 long tons; 25,000 t) of steel, manufactured by the American Bridge Company . The superstructure of the Fulton Building was intended to carry a dead load of 95 pounds per square foot (4.5 kPa ) and
11100-596: The complex on the East River , on the opposite side of Lower Manhattan from Hudson Terminal. As an interstate agency, the Port Authority required approval for its projects from both New Jersey's and New York's state governments, but the New Jersey government objected that the proposed trade center would mostly benefit New York. In late 1961, Port Authority executive director Austin J. Tobin proposed shifting
11250-482: The complex's existence, the buildings experienced several incidents. Within a year of the office building's opening, in 1909, a man died after falling from a window in the Fulton Building; other deaths from falling occurred in 1927 and 1940. A bag full of explosives was found in the terminal in 1915, with enough explosives to blow up several buildings of the Hudson Terminal towers' size. The elevators were also involved in several accidents: two people were slightly injured by
11400-414: The display of the transit network. Often this has the effect of compressing the distance between stations in the outer area of the system, and expanding distances between those close to the center. Some systems assign unique alphanumeric codes to each of their stations to help commuters identify them, which briefly encodes information about the line it is on, and its position on the line. For example, on
11550-611: The entire metropolitan area is called Metra (short for Met ropolitan Ra il), while its rapid transit system that serves the city is called the "L" . Boston's subway system is known locally as "The T". In Atlanta , the Metropolitan Atlanta Rapid Transit Authority goes by the acronym "MARTA." In the San Francisco Bay Area , residents refer to Bay Area Rapid Transit by its acronym "BART". The New York City Subway
11700-408: The financial strains of the war delayed progress. The Council chose a site at the old Common at the northern limits of the city, now City Hall Park . City Hall was originally an area for the first almshouse in 1653. In 1736, there was a financed almshouse for those who were fit to work, for the unfit, and those that were like criminals but were paupers. In 1802, New York City held a competition for
11850-574: The firm Clinton and Russell in the Romanesque Revival style. The basements contained facilities such as a shopping concourse, an electrical substation , and baggage areas. The complex could accommodate 687,000 people per day, more than Pennsylvania Station in Midtown Manhattan . The buildings opened first, being the world's largest office buildings upon their completion, and the terminal station opened afterward. The H&M
12000-405: The firm Clinton and Russell , and built by construction contractor George A. Fuller . Purdy and Henderson were retained as the structural engineers. Located on what would later become the World Trade Center site , the Hudson Terminal buildings preceded the original World Trade Center complex in both size and function. When the Hudson Terminal buildings opened, the height and design of skyscrapers
12150-412: The first basement level. The floor surface of each ramp is made of a compound of cement and carborundum . The original plans had called for one ramp each from Cortlandt and Fulton Streets and two from Dey Street, but the engineers deemed this to be impractical. There were also two bluestone staircases from Dey Street. At the end of each ramp or staircase, Karl Bitter designed a large clock face, and there
12300-412: The five tracks. The basements also contained a training school and break rooms for the H&M Railroad, as well as an ice-making plant, elevator hydraulic pumps, a generating plant, and a storage battery. Hudson Terminal's electrical substation consisted of two 1,500-kilowatt (2,000 hp) rotary converters for the railroad and four 750-kilowatt (1,010 hp) rotaries for the buildings. This equipment
12450-516: The floor rather than resting on ballast , such as normal railway tracks. An alternate technology, using rubber tires on narrow concrete or steel roll ways , was pioneered on certain lines of the Paris Métro and Mexico City Metro , and the first completely new system to use it was in Montreal , Canada. On most of these networks, additional horizontal wheels are required for guidance, and
12600-439: The interconnections between different parts of the system; for example, they show the interchange stations where passengers can transfer between lines. Unlike conventional maps, transit maps are usually not geographically accurate, but emphasize the topological connections among the different stations. The graphic presentation may use straight lines and fixed angles, and often a fixed minimum distance between stations, to simplify
12750-494: The interior and exterior. Due to the complexity of the demands of the project, the New York City Department of Design and Construction hired Hill International to provide construction management. Renovations were originally estimated to cost $ 104 million and take four years, but ended up costing nearly $ 150 million and taking over five years. Although Mangin and McComb designed the building, which
12900-412: The land. The 70,000 square feet (6,500 m) acquired for the complex had cost an average of $ 40 to $ 45 per square foot ($ 430 to $ 480/m). The New York Times predicted that the development of Hudson Terminal would result in the relocation of many manufacturing plants from New Jersey to Lower Manhattan. Excavations at the site of the office buildings were underway by early 1907, and the first columns for
13050-602: The lines of the Lyon Metro includes a section of rack (cog) railway , while the Carmelit , in Haifa, is an underground funicular . For elevated lines, another alternative is the monorail , which can be built either as straddle-beam monorails or as a suspended monorail . While monorails have never gained wide acceptance outside Japan, there are some such as Chongqing Rail Transit 's monorail lines which are widely used in
13200-439: The low-rise buildings on Greenwich Street to expand the Hudson Terminal buildings. Upon the tubes' opening, they were also popular with New Jersey residents who wanted to travel to New York City. Passenger volume at Hudson Terminal had reached 30,535,500 annually by 1914, and within eight years, nearly doubled to 59,221,354. Several modifications were made to the complex in the years after its completion. Smaller annexes were added to
13350-472: The main corridors of each level on both buildings extended eastward from Church Street. The Cortlandt Building's light courts measured 32 by 76 feet (9.8 by 23.2 m), while the Fulton Building's light courts were 48 by 32 feet (14.6 by 9.8 m). The wings on either side of the light courts were of asymmetrical width. The main roofs of the buildings were carried to 275.75 feet (84.05 m) above ground. Small projecting "towers" with pitched roofs rose from
13500-557: The main rapid transit system. For instance, the Wenhu Line of the Taipei Metro serves many relatively sparse neighbourhoods and feeds into and complements the high capacity metro lines. Some systems have been built from scratch, others are reclaimed from former commuter rail or suburban tramway systems that have been upgraded, and often supplemented with an underground or elevated downtown section. Ground-level alignments with
13650-600: The medium by which passengers travel in busy central business districts ; the use of tunnels inspires names such as subway , underground , Untergrundbahn ( U-Bahn ) in German, or the Tunnelbana (T-bana) in Swedish. The use of viaducts inspires names such as elevated ( L or el ), skytrain , overhead , overground or Hochbahn in German. One of these terms may apply to an entire system, even if
13800-418: The network map "readable" by illiterate people, this system has since become an "icon" of the system. Compared to other modes of transport, rapid transit has a good safety record, with few accidents. Rail transport is subject to strict safety regulations , with requirements for procedure and maintenance to minimize risk. Head-on collisions are rare due to use of double track, and low operating speeds reduce
13950-402: The next vehicle will arrive, and expected travel times. The standardized GTFS data format for transit information allows many third-party software developers to produce web and smartphone app programs which give passengers customized updates regarding specific transit lines and stations of interest. Mexico City Metro uses a unique pictogram for each station. Originally intended to help make
14100-421: The north and south of the station, each end of the loop had a loading gauge large enough to fit one train. The cars required a clearance of 12 feet 6 inches (3.81 m) above the tops of the rails, while the floor of the tunnel was 24 inches (610 mm) below the tops of the rails. The single tubes of the Downtown Tubes enabled better ventilation of the station by the so-called piston effect . When
14250-958: The occurrence and severity of rear-end collisions and derailments . Fire is more of a danger underground, such as the King's Cross fire in London in November 1987, which killed 31 people. Systems are generally built to allow evacuation of trains at many places throughout the system. High platforms , usually over 1 meter / 3 feet, are a safety risk, as people falling onto the tracks have trouble climbing back. Platform screen doors are used on some systems to eliminate this danger. Rapid transit facilities are public spaces and may suffer from security problems: petty crimes , such as pickpocketing and baggage theft, and more serious violent crimes , as well as sexual assaults on tightly packed trains and platforms. Security measures include video surveillance , security guards , and conductors . In some countries
14400-491: The office buildings at some point after they opened, during the early or mid-20th century. A passageway to the Independent Subway System (IND)'s Chambers Street station was opened in 1949. The passageway measured 14 feet (4.3 m) wide and 90 feet (27 m) long. Construction contractor Great Atlantic Construction Company described the tunnel as "one of the most difficult of engineering feats", as
14550-579: The office of the Mayor of New York City and the chambers of the New York City Council . While the Mayor's Office is in the building, the staff of thirteen municipal agencies under mayoral control are located in the nearby Manhattan Municipal Building , one of the largest government buildings in the world, with many others housed in various buildings in the immediate vicinity. New York City Hall
14700-496: The old City Hall, was a New Yorker and designed Castle Clinton in Battery Park, among other buildings and structures. Mangin had no known involvement with City Hall after winning the commission. McComb alone supervised every aspect of construction and was in charge of the architectural modifications and detailing during the extended building process. The cornerstone of the new City Hall was laid on May 26, 1803. Construction
14850-603: The only two North American systems that are primarily called "subways". In most of Southeast Asia and in Taiwan , rapid transit systems are primarily known by the acronym MRT . The meaning varies from one country to another. In Indonesia , the acronym stands for Moda Raya Terpadu or Integrated Mass [Transit] Mode in English. In the Philippines , it stands for Metro Rail Transit . Two underground lines use
15000-413: The other. This removed conflicts between departing and boarding passengers. The width of the station averaged 180 feet (55 m) from west to east, and the station measured 530 feet (160 m) long from north to south. Lower Manhattan's topography made it impossible for the H&M to build a "stub-end" terminal, with the tracks oriented on a west–east axis and terminating at bumper blocks . Therefore,
15150-587: The outset. Budapest , Chicago , Glasgow , Boston and New York City all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services. Hybrid solutions have also evolved, such as tram-train and premetro , which incorporate some of the features of rapid transit systems. In response to cost, engineering considerations and topological challenges some cities have opted to construct tram systems, particularly those in Australia, where density in cities
15300-471: The passageway had to pass above the H&M tunnels while avoiding various pipes, wires, water mains, and cable car lines. Early tenants of the Hudson Terminal buildings included companies in the railroad industry; the offices of U.S. Steel ; and some departments of New York City's general post office, which had been crowded out of its older building . U.S. Steel, the post office, and six railroad companies occupied 309,000 square feet (28,700 m), or over
15450-512: The presence of the tracks on the second basement level, and the cofferdam was said to be five times larger than any other similar structure previously constructed. The perimeter of the foundation was excavated using 51 pneumatic caissons , drilled to depths of between 75 and 98 feet (23 and 30 m), with an average depth of 80 feet (24 m). This required the underpinning of every building nearby. The caissons were made of reinforced concrete with 8-foot-thick (2.4 m) walls. At this location,
15600-489: The project to Hudson Terminal and taking over the H&M in exchange for New Jersey's agreement. On January 22, 1962, the two states reached an agreement to allow the Port Authority to take over the railroad, rebrand it as the Port Authority Trans-Hudson (PATH), and build the World Trade Center on the Hudson Terminal site, which was by then deemed obsolete. The World Trade Center project would include
15750-470: The railroad, but the Port Authority had long viewed it as unprofitable. In 1958, the investment firm Koeppel & Koeppel offered to buy the terminal buildings for $ 15 million (equivalent to $ 122 million in 2023), as part of a reorganization hearing for the H&M. The Port Authority ultimately took over the H&M as part of an agreement concerning the construction of the World Trade Center . The Port Authority had initially proposed constructing
15900-908: The rapid transit system varies greatly between cities, with several transport strategies. Some systems may extend only to the limits of the inner city, or to its inner ring of suburbs with trains making frequent station stops. The outer suburbs may then be reached by a separate commuter rail network where more widely spaced stations allow higher speeds. In some cases the differences between urban rapid transit and suburban systems are not clear. Rapid transit systems may be supplemented by other systems such as trolleybuses , regular buses , trams , or commuter rail. This combination of transit modes serves to offset certain limitations of rapid transit such as limited stops and long walking distances between outside access points. Bus or tram feeder systems transport people to rapid transit stops. Each rapid transit system consists of one or more lines , or circuits. Each line
16050-546: The rear elevation, had deteriorated over time from pollution and pigeons. It was completely reclad in Alabama limestone above a Missouri granite base in 1954–56 by Shreve, Lamb & Harmon , architects of the Empire State Building . The steps of City Hall frequently provide a backdrop for political demonstrations and press conferences concerning city politics. Live, unedited coverage of events at City Hall
16200-542: The rubber tires. However, they have higher maintenance costs and are less energy efficient. They also lose traction when weather conditions are wet or icy, preventing above-ground use of the Montréal Metro and limiting it on the Sapporo Municipal Subway, but not rubber-tired systems in other cities. Some cities with steep hills incorporate mountain railway technologies in their metros. One of
16350-451: The same public transport authorities . Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. The world's first rapid transit system was the partially underground Metropolitan Railway which opened in 1863 using steam locomotives , and now forms part of the London Underground . In 1868, New York opened the elevated West Side and Yonkers Patent Railway , initially
16500-411: The site bounded by Cortlandt Street to the south, Church Street to the east, and Fulton Street to the west, with the northern building at 50 Church Street and the southern building at 30 Church Street. The site was also abutted by several low-rise buildings on Greenwich Street to the west. They were respectively called the Fulton Building and the Cortlandt Building, and were also collectively referred to as
16650-462: The soaring rotunda dome – as did Colonel Elmer Ephraim Ellsworth , first Union officer killed in the Civil War and commander of the 11th New York Volunteer Infantry Regiment (First Fire Zouaves). There are 108 paintings from the late 18th century through the 20th century, which The New York Times declared were "almost unrivaled as an ensemble, with several masterpieces". Among the collection
16800-449: The southern office building was called the Cortlandt Building, reflecting the streets that they abutted. The H&M terminal opened on July 19, 1909, along with the Downtown Tubes. The combined rail terminal and office block was the first of its kind anywhere in the world. The space in the office buildings was in high demand, and the offices were almost fully rented by 1911. The following year, McAdoo denied rumors that H&M would acquire
16950-453: The substructure were placed in May 1907. Because of the presence of wet soil in the area, and the proximity of the Hudson River immediately to the west, a cofferdam was built around the site of the Hudson Terminal buildings. According to architectural writers Sarah Landau and Carl W. Condit , the cofferdam was five times larger than any such structure previously constructed. At the time, there
17100-663: The suburbs, allowing a higher service frequency in the center. This arrangement is used by many systems, such as the Copenhagen Metro , the Milan Metro , the Oslo Metro , the Istanbul Metro and the New York City Subway . Alternatively, there may be a single central terminal (often shared with the central railway station), or multiple interchange stations between lines in the city center, for instance in
17250-714: The term subway . In Thailand , it stands for Metropolitan Rapid Transit , previously using the Mass Rapid Transit name. Outside of Southeast Asia, Kaohsiung and Taoyuan, Taiwan , have their own MRT systems which stands for Mass Rapid Transit , as with Singapore and Malaysia . In general rapid transit is a synonym for "metro" type transit, though sometimes rapid transit is defined to include "metro", commuter trains and grade separated light rail . Also high-capacity bus-based transit systems can have features similar to "metro" systems. The opening of London's steam-hauled Metropolitan Railway in 1863 marked
17400-467: The term Subway into railway terminology. Both railways, alongside others, were eventually merged into London Underground . The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset. The technology quickly spread to other cities in Europe , the United States, Argentina, and Canada, with some railways being converted from steam and others being designed to be electric from
17550-524: The terminal. Rapid transit Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks . Some systems use guided rubber tires , magnetic levitation ( maglev ), or monorail . The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by
17700-404: The time of its construction, there were plans to build another pair of tunnels under the Hudson River near the Downtown Tubes. The H&M anticipated that two terminal tracks would be needed for each pair of tunnels; the fifth track was needed for flexibility. The additional tunnels were ultimately never built, and several subway tunnels were built very close to the Hudson Terminal complex. Track 5,
17850-595: The tunnels. The Hudson Terminal station closed on July 2, 1971, to allow a three-day maintenance period to divert service to its replacement, the original World Trade Center PATH station . The World Trade Center station opened on July 6, 1971, west of the Hudson Terminal station. Just before the buildings' demolition, in early 1972, the New York City Fire Department used the empty Cortlandt Building for several fire safety tests, setting fires to collect data for fire safety. The Hudson Terminal complex
18000-424: The underlying rock layer descended a maximum of 110 feet (34 m) beneath Church Street. Within the interiors of the enclosed cofferdam, 115 circular pits and 32 rectangular pits were dug. The steel columns supporting the superstructure were then placed in the pits; they weighed up to 26 short tons (23 long tons; 24 t) and could carry loads of 1,725 short tons (1,540 long tons; 1,565 t). The entire lot area
18150-601: The use of communications-based train control : the minimum headway can reach 90 seconds, but many systems typically use 120 seconds to allow for recovery from delays. Typical capacity lines allow 1,200 people per train, giving 36,000 passengers per hour per direction . However, much higher capacities are attained in East Asia with ranges of 75,000 to 85,000 people per hour achieved by MTR Corporation 's urban lines in Hong Kong. Rapid transit topologies are determined by
18300-757: The west; the Broadway–Chambers Building to the northwest; 280 Broadway , 49 Chambers , Tweed Courthouse , and Surrogate's Courthouse to the north; the Manhattan Municipal Building to the northeast; the Brooklyn Bridge to the east; and the New York Times Building , the Potter Building , and the Park Row Building to the southwest. City Hall Park is approximately three blocks away from
18450-423: The westernmost side platform or the baggage room in the third basement. Four elevators also transported baggage from the baggage room to the end of each of the island platforms. Each of the freight elevators had a capacity of 13,000 pounds (5,900 kg), while each of the island-platform elevators had a capacity of 8,000 to 13,000 pounds (3,600 to 5,900 kg). Thus, baggage could be transported to trains on any of
18600-491: The westernmost track, was used by baggage trains and was designated as the "emergency" track. The westernmost side platform, serving Track 5, was used for handling baggage, delivering coal, and depositing ashes from the buildings' power station. The easternmost side platform adjacent to track 1, as well as the island platforms between tracks 2/3 and 4/5, were used by alighting passengers only. The island platforms between tracks 1/2 and 3/4 were used by boarding passengers. The station
18750-481: The width of the trains. The eastern side platform was 11.5 feet (3.5 m) wide because it was used only by alighting passengers from track 1, and the island platform for alighting passengers between tracks 4/5 was 13 feet (4.0 m) wide because track 5 was not used in regular service. The other three island platforms were 22 feet (6.7 m) wide because they each served two tracks that were used in regular passenger service. The engineers studied pedestrian traffic at
18900-559: Was Singapore's Mass Rapid Transit (MRT) system, which launched its first underground mobile phone network using AMPS in 1989. Many metro systems, such as the Hong Kong Mass Transit Railway (MTR) and the Berlin U-Bahn, provide mobile data connections in their tunnels for various network operators. The technology used for public, mass rapid transit has undergone significant changes in the years since
19050-403: Was a Portland concrete slab 36 inches (910 mm) thick. The platforms contained columns at intervals of about every 20 feet (6.1 m). Some of the girders in the substructure were spaced irregularly because of the placement of the railroad platforms at the second basement level. Heavy sets of three distributing girders, encased in concrete, were used in these locations to support the weight of
19200-421: Was a lot of office space being developed in Lower Manhattan, even as the area saw a decrease in real-estate transactions. The project was completed for $ 8 million (equivalent to $ 191 million in 2023). The buildings were owned by the H&M Railroad upon their completion. By April 4, 1908, tenants started moving into the towers. Originally, the northern office building was called the Fulton Building while
19350-445: Was also a steel and glass marquee protruding onto the sidewalk. According to Landau and Condit, "At full capacity, the Hudson Terminal could accommodate 687,000 people per day; in comparison, Pennsylvania Station (1902–1910) was designed with a capacity of 500,000." The concourse, on the first basement level, contained ticket offices, waiting rooms, and some retail shops. It measured 430 by 185 feet (131 by 56 m), much of which
19500-458: Was concentrated around the neighborhood of Exchange Place , while traffic in Lower Manhattan was centered south of New York City Hall . In addition, low construction costs and low property values were considerations in selecting the location of the railroad's Lower Manhattan terminal. The H&M only searched for sites west of Broadway , since there were more transit connections and fewer existing buildings west of that street. Land acquisition for
19650-529: Was constructed between 1810 and 1812, it has been altered numerous times over the years by several architects. These include Leopold Eidlitz in 1860, John H. Duncan in 1898, William Martin Aiken in 1903, Grosvenor Atterbury from 1907 to 1917, Shreve, Lamb & Harmon in 1956, and Cabrera Barricklo in 1998. The architectural style of City Hall combines international architectural influences, French Renaissance and English neoclassicism. American- Georgian
19800-462: Was crumbling. On July 23, 2003, at 2:08 p.m., City Hall was the scene of a rare political assassination. Othniel Askew , a political rival of City Councilman James E. Davis , opened fire with a pistol from the balcony of the City Council chamber. Askew shot Davis twice, fatally wounding him. A police officer on the floor of the chamber then fatally shot Askew. Askew and Davis had entered
19950-477: Was delayed after the City Council objected that the design was too extravagant. In response, McComb reduced the size of the building and used brownstone at the rear of the building to lower costs. The brownstone, along with the original deteriorated Massachusetts marble facade, quarried from Alford, Massachusetts , was later replaced with Alabama limestone between 1954 and 1956. Labor disputes and an outbreak of yellow fever further slowed construction. The building
20100-421: Was demolished by the end of 1972. After the World Trade Center station opened, the sections of the Downtown Tubes between the Hudson Terminal and World Trade Center stations were taken out of service and turned into loading docks for the 4 World Trade Center and 5 World Trade Center buildings on Church Street. The original PATH station was destroyed in 2001 during the September 11 attacks . The last remnant of
20250-572: Was demolished in 1690. The city's second City Hall, built in 1700, stood on Wall and Nassau Streets . That building was renamed Federal Hall in 1789, after New York became the first official capital of the United States after the Constitution was ratified. It was demolished in 1812 and current Federal Hall was built in 1842. Plans for building a new City Hall were discussed by the New York City Council as early as 1776, but
20400-412: Was designed to accommodate a full trainload of 800 passengers every 90 seconds, the maximum capacity of the Downtown Tubes. Each of the platforms were 370 feet (110 m) long and could fit trains of eight 48.5-foot-long (14.8 m) cars. The platform widths were determined by the projected passenger loads for each track; the boarding platforms were wider than the alighting platforms and at least twice
20550-437: Was designed to be the showpiece of the new subway. The platform and mezzanine feature Guastavino tile , skylights, colored glass tile work and brass chandeliers. Passenger service was discontinued on December 31, 1945, although the station is still used as a turning loop for 6 and <6> trains. Another station named City Hall ( N , R , and W trains) also exists on
20700-899: Was developed further. Other Central European countries also have metro lines, for example in the cities of Budapest (Hungary), Prague (Czech Republic) and Warsaw (Poland). In Eastern Europe , metro systems are in operation in Minsk (Belarus), Kyiv (Ukraine), Riga (Latvia), Vilnius (Lithuania) and Moscow (Russia). In Southeastern European countries, there are metro systems in Athens and Thessaloniki (Greece), Belgrade (Serbia), Sofia (Bulgaria) and Istanbul (Turkey). In Northern Europe , rapid transit systems exist in Copenhagen (Denmark), Oslo (Norway), Stockholm (Sweden) and Helsinki (Finland). Various terms are used for rapid transit systems around North America . The term metro
20850-525: Was filled with glass. The top six stories of each building contained light-toned terracotta, as in the original plan. The corners of each building had light terracotta strips as well. Tall arches connected three of the top six stories. Because of the differing dimensions of the buildings, the Fulton Building had eighteen bays facing Church Street and nineteen facing Dey Street, while the Cortlandt Building had twenty-two bays facing Church Street and twenty facing Cortlandt Street. The two buildings were connected by
21000-481: Was incorporated in December 1906 to operate the Hudson & Manhattan Railroad (H&M), a passenger railroad system headed by William Gibbs McAdoo , which would use the tubes. The system connected Hoboken , Pavonia , and Exchange Place , three of the five major railroad terminals on the western shore of the Hudson River waterfront . At the time, there was high passenger traffic between New Jersey and Lower Manhattan. Passenger and mass-transit traffic in Jersey City
21150-702: Was low and suburbs tended to spread out . Since the 1970s, the viability of underground train systems in Australian cities, particularly Sydney and Melbourne , has been reconsidered and proposed as a solution to over-capacity. Melbourne had tunnels and stations developed in the 1970s and opened in 1980. The first line of the Sydney Metro was opened in 2019. Since the 1960s, many new systems have been introduced in Europe , Asia and Latin America . In
21300-500: Was not dedicated until 1811, and opened officially in 1812. The New York City Police riot occurred in front of New York City Hall between the recently dissolved New York Municipal Police and the newly formed Metropolitan Police on June 16, 1857. Municipal police fought with Metropolitan officers who were attempting to arrest New York City Mayor Fernando Wood . In 1953, the city's public works commissioner Frederick H. Zurmuhlen requested $ 2.2 million to repair City Hall's facade, which
21450-475: Was open pedestrian space. The floor of the concourse was made of white terracotta with colored mosaic bands, while the columns and walls were made of plaster wainscoted with white terracotta. The concourse contained a dropped ceiling , concealing some utility pipes and wires placed beneath the main ceiling. The basements were equipped with baggage handling facilities for the baggage trains traveling on Track 5. Two freight elevators carried baggage from Dey Street to
21600-430: Was oriented further northwestward compared to the Hudson Terminal station parallel to Church Street. Because it was longer than the Hudson Terminal station, a large jughandle curve was built from either tube to the World Trade Center station, surrounding the Hudson Terminal approach tracks. The sections of the tubes east of Greenwich Street were subsequently turned into loading docks serving 4 and 5 World Trade Center. To
21750-425: Was overseen by Charles H. Jacobs, chief engineer, and J. Vipond Davies, deputy chief engineer. The terminal was two stories below street level and consisted of five tracks numbered 1–5 from east to west. The tracks were served by four island platforms and two side platforms . All tracks had a Spanish solution layout with platforms on both sides, thereby enabling passengers to exit trains from one side and enter from
21900-474: Was placed 75.8 feet (23.1 m) below ground level at Church Street. From the Hudson and Manhattan Railroad Powerhouse in Jersey City, an 11,000- volt line of alternating current transmitted power to Hudson Terminal, where it was converted to 625 volts of direct current for the railroad and 240V DC for the offices. The O'Rourke Engineering and Contracting Company were hired to build the complex's foundation . The foundation used irregular framing because of
22050-445: Was still heavily debated, and New York City skyscrapers were criticized for their bulk and density. Some of the city's early-20th-century skyscrapers were thus designed with towers, campaniles, or domes above a bulky base, while others were divided into two structures, as at Hudson Terminal. Furthermore, high real-estate costs made it impractical to build "anything but an office building" above the terminal. The buildings occupied most of
22200-503: Was successful until the mid-20th century, when it went bankrupt. The railroad and Hudson Terminal were acquired in 1962 by the Port Authority of New York and New Jersey , which rebranded the railroad as Port Authority Trans-Hudson (PATH) . The Port Authority agreed to demolish Hudson Terminal to make way for the World Trade Center , and the railroad station closed in 1971, being replaced by PATH's World Trade Center station . While
22350-423: Was then excavated to the second basement level. Part of the third basement was also excavated down to bedrock. Overall, 238,000 cubic yards (182,000 m) of earth were excavated manually and 80,000 cubic yards (61,000 m) excavated via caissons. The main girders at the Hudson Terminal station's platform level were 48 inches (1,200 mm) deep with flanges 16 inches (410 mm) wide. The floor of this level
22500-417: Was used to encase the structural steel frame. The I-beams were supported by columns or on plate girders . Large wind braces were not used; instead, the flanges of the beams and girders were riveted to the columns with what the Engineering Record described as "a moment of stiffness equal or somewhat superior to the depth of the girder". The towers had a combined 39 elevators, which could carry 30,000 people
