The Port Authority Trans-Hudson (PATH) is a rapid transit railroad linking Manhattan, New York with New Jersey, and providing service to Jersey City, Hoboken, Harrison, and Newark. It is operated by the Port Authority of New York and New Jersey. PATH is one of the few rapid transit systems in the world that operates 24 hours a day, 7 days a week. While some PATH stations are adjacent to New York City Subway, Newark Light Rail and Hudson-Bergen Light Rail stations, there are no free transfers as the four systems operate independently.

PATH spans 13.8 miles (22.2 km) of route mileage, not including any route overlap.^[2]

PATH trains only use tunnels in Manhattan and parts of New Jersey (specifically, Hoboken and downtown Jersey City). The tracks cross the Hudson River through century-old cast iron tubes that rest on the river bottom under a thin layer of silt. PATH's routes from Grove Street in Jersey City west to Newark run in open cuts, at grade level, and on elevated track.

As of 2006, PATH has an average weekday ridership of 239,200.^[3]

The history of PATH, originally known as the Hudson and Manhattan Railroad, predates the first underground line of the New York City Subway (the IRT). Although the railroad was first planned in 1874, existing technologies could not safely tunnel under the Hudson River. Construction began on the existing tunnels in 1890, but stopped shortly thereafter when funding ran out. Indeed, construction did not resume until 1900 under the direction of William Gibbs McAdoo, an ambitious, young lawyer who had moved to New York from Tennessee. McAdoo would later become president of what would, for many years, be known as the H&M, Hudson Tubes or McAdoo Tunnels.^[4]

The first tunnel (the northernmost of the uptown pair) was originally built without an excavation shield or iron construction because the chief engineer of the time, DeWitt Haskins, believed that the river silt was strong enough to maintain the tunnel's form (with the help of compressed air) until a 2 1/2 foot (76 cm) thick brick lining could be constructed. Haskins' plan was to excavate the tunnel, then fill it with compressed air to expel the water and to hold the iron plate lining in place. They succeeded in building the tunnel out by approximately 1,200 feet (366 m) from Jersey City until a series of blowouts — including a particularly serious one in 1880 that took the lives of 20 workers — ended the project.^[5]

When the New York and Jersey Tunnel Company resumed construction on the tunnels in 1902, they employed a different method of tunneling using tubular cast iron plating. An enormous mechanical shield was pushed through the silt at the bottom of the river. The displaced mud would then be placed into a chamber, where it would later be shoveled into small cars that hauled it to the surface.^{[citation needed]} In some cases, the silt would be baked with kerosene torches to facilitate easier removal of the mud. The southernmost tunnel of the uptown pair, as well as the downtown tunnels, were all constructed using the tubular cast iron method.

• The tunnels are separate for each track, which enables a better ventilation by so-called piston effect. When a train passes through the tunnel it pushes out the air in front of it toward the closest ventilation shaft it front, and "sucks-in" the air to the tunnel from the closest ventilation shaft behind it.

The tunnels in Manhattan, on the other hand, employed cut and cover construction methods.

The first trains ran in 1907 and revenue service started between Hoboken and 19th Street at midnight on February 26, 1908. On July 19, 1909, service began between Lower Manhattan and Jersey City, through a set of tunnels located about 1 1/4 miles (2 km) south of the first pair. After the completion of the uptown Manhattan extension to 33rd Street and the westward extension to Newark and the now-defunct Manhattan Transfer in 1911, the Hudson and Manhattan Railroad was considered to be complete. The cost of the entire project was estimated at between $55 and $60 million, equal to more than $1 billion in present-day dollars.^{[citation needed]}

Originally, the Hudson Tubes were designed to link the major railroad stations in New Jersey — the Lackawanna station in Hoboken, the Erie and PRR stations in Jersey City — with New York City. While it still provides a connection to train stations in Hoboken and Newark, the commuter train stations at Erie (now Pavonia-Newport) and Exchange Place (the PRR station) have since closed down. In recent years, the old rail yards at Pavonia and Exchange Place have been replaced with large-scale office, residential, and retail developments.

The original plan included an agreement between H&M and the Pennsylvania Railroad whereby PRR traffic headed for Lower Manhattan would transfer at Manhattan Transfer to the Hudson Tubes, and H&M would operate all traffic — ferry, train, or tube — between Lower Manhattan and Newark. The Tubes would also take over operation of the Jersey City Pennsylvania Railroad Harborside Terminal station at Exchange Place, when the new Pennsylvania Station in midtown Manhattan were to open, which would have its own tunnel under the Hudson River.^{[citation needed]} Penn Station in Manhattan did open some ten years later, but the plans had changed; the PRR maintained operation of its Jersey City Station and they also maintained their ferries between Exchange Place and Lower Manhattan. Additionally, the route between Journal Square (then Summit Avenue) and Newark became a joint operation of the H&M and PRR.

Attempts to extend the Tubes to Astor Place and Grand Central Terminal failed, even after some construction began on the extension. There was also a plan to build an extension from the curve west of Hoboken Terminal to where Secaucus Junction is now, and a plan for a north-south connection from the 33rd Street Station south on Broadway to Union Square and then a new alignment to Hudson Terminal.

The opening of the Holland Tunnel in 1927, coupled with the Depression that began shortly after, marked the decline of the Hudson and Manhattan Railroad. Later, the construction of the Lincoln Tunnel and the George Washington Bridge further enticed people away from the railroad. All of these tunnels were intended to increase the flow of auto-traffic, providing an alternative to the railway.

• February 25, 1908: The uptown tubes open from 19th Street to Hoboken Terminal.^[6]
• June 15, 1908: The H&M is extended from 19th Street to 23rd Street.^[7]
• July 19, 1909: The downtown tubes open from Hudson Terminal to Exchange Place.^[8]
• August 2, 1909: The New Jersey-side connection opens, between Exchange Place and the junction near Hoboken Terminal.^[9]
• September 6, 1910: The H&M is extended from Exchange Place west to Grove Street.^[10]
• November 10, 1910: The H&M is extended from 23rd Street to 33rd Street.^[11][12]
• November 27, 1910: The PRR tunnel to New York Penn Station opens.^[13]
• October 1, 1911: The H&M is extended from Grove Street west to Manhattan Transfer.^[14]
• November 26, 1911: The H&M opens to Park Place, Newark.^[15]
• June 20, 1937: Manhattan Transfer is closed and the H&M is realigned to Newark Penn Station; the Harrison station is moved several blocks south. On the same day, the Newark City Subway is extended to Newark Penn Station. The upper level of the Centre Street Bridge to Park Place later became Route 158.^[16]

Promotions and other advertising proved ineffectual at slowing the financial decline. In the 1950s, H&M fell into bankruptcy, but continued to operate. It remained under bankruptcy court protection for years, a source of embarrassment. For decades, New Jersey politicians asked the Port Authority to operate the vital transit link, but Port Authority officials were reluctant to assume the money-losing operation, and New York politicians did not want extra Port Authority money spent in New Jersey.

The World Trade Center finally enabled the three parties to compromise. The Port Authority agreed to purchase and maintain the Tubes in return for the rights to build the World Trade Center on the land occupied by H&M's Hudson Terminal, which was the Lower Manhattan terminus of the Tubes.

In 1962, the Hudson and Manhattan Railroad Company ceased operation of the Hudson Tubes, and service began through the Port Authority Trans-Hudson Corporation (PATH), a subsidiary organization of the Port Authority. Upon taking over the H&M Railroad, the Port Authority spent $70 million to modernize PATH's infrastructure.^[17]

The World Trade Center station, which is one of PATH's two New York terminals, was destroyed on September 11, 2001. Just prior to the collapse, the station was closed and any waiting passengers that were in the station were evacuated by a train that was already inside the terminal.

With the station destroyed, service to Lower Manhattan was suspended for over two years. Exchange Place, the next station on the Newark–World Trade Center line, also had to be closed because it could not operate as a "terminal" station.^[18] Instead, two uptown services (Newark–33rd Street (red) and Hoboken–33rd Street (blue)) and one intra-state New Jersey service (Hoboken-Journal Square (green)) were put into operation. Only one after-hours train was put into service, Newark–33rd Street (via Hoboken).

Modifications were made to a stub end tunnel (also known as the Penn Pocket, which was originally built for short turn World Trade Center to Exchange Place runs to handle PRR commuters from Harborside Terminal) to allow trains from Newark to reach the Hoboken bound tunnel and vice versa. The modifications required PATH to bore through the bedrock dividing the stub tunnel and the tunnels to and from Newark. The new Exchange Place station opened in June 2003. Because of the original alignment of the tracks, trains to/from Hoboken use separate tunnels from the Newark service.^{[citation needed]} From Newark, trains would cross over to the Newark/Hoboken bound track just north of Exchange Place. The train would then reverse direction and go to Hoboken. From Hoboken, trains would enter on the Manhattan bound track at Exchange Place. The train would then reverse direction and use several switches west of the station to go to the Newark bound tracks before entering Grove Street.^{[citation needed]}

PATH service to Lower Manhattan was restored when a $323 million temporary station opened on November 23, 2003; the inaugural train was the same one that had been used for the evacuation. The new station still contains portions of the original station but it does not have heating or air conditioning systems installed, and is very functional in its design. The temporary entrance was closed and demolished on July 1, 2007 to make way for the permanent station, with the Church Street station open. ^[19] On April 11, 2007, the Port Authority announced that it will build a new entrance to the World Trade Center PATH station on Vesey Street. The entrance is expected to open by the end of 2007.^[20] The permanent World Trade Center PATH station, expected to be complete by 2009 at a cost of $2 billion, will likely be paid for through insurance settlements relating to the events of September 11th and through taxpayer funds from the states of New York and New Jersey.^{[citation needed]} This project, according to The Star-Ledger of Newark, has been awarded to a joint-venture of Granite Construction North-East (formally Granite Halmar), Fluor Enterprises, Bovis Lend Lease, and Slattery Skanska.

On July 7, 2006, an alleged plot to detonate explosives in the PATH tunnels (initially said to be a plot to bomb the Holland Tunnel) was uncovered by the Federal Bureau of Investigation. The plot included the detonation of a bomb that could significantly destroy and flood the tunnels, endangering all the occupants and vehicles in the tunnel at the time of the explosion. The terror planners believed that Lower Manhattan could, as a result of the explosion, be flooded due to river water surging up the remaining tunnel after the blast. Officials say that this plan was unsound due to the strength of the tunnels, and that it would require a large amount of explosives to explode. Since semi-trailer trucks are currently not allowed to pass through the Holland Tunnel, and it would be unfeasible to carry such a bomb on board a PATH train, it would be very difficult to get sufficient explosives into the tunnel to accomplish the plan. If the tunnel were to explode and allow water from the Hudson River to flood the (Holland) tunnel, Lower Manhattan would be spared since the area is 2-10 feet (1-3 meters) above sea level. Three of the eight planners have been arrested, based in six different countries. ^[21]

PATH operates 24 hours a day, seven days a week. During normal hours, PATH operates four train services, using three terminals in New Jersey and two in Manhattan. Each line is represented by a unique color, which also corresponds to the color of the lights on the front of the trains. The Journal Square–33rd Street service is the only line represented by two colors (yellow and blue), since it is an after-hours combination of the Journal Square–33rd Street and Hoboken–33rd Street services.

• Newark–World Trade Center
• Hoboken–World Trade Center
• Journal Square–33rd Street
• Hoboken-33rd Street

After 23:00 and before 06:00 Monday to Friday, and all-day Saturday, Sunday, and holidays, PATH operates two train services:

• Newark–World Trade Center
• Journal Square–33rd Street

Prior to April 9, 2006, Hoboken–World Trade Center and Journal Square–33rd Street services were offered on Saturday, Sunday, and holidays between 09:00 and 19:30. Ongoing construction of the permanent World Trade Center Station in Manhattan prompted the indefinite discontinuation of these services on Saturdays, Sundays, and holidays. They have been replaced with an all-day Journal Square–33rd Street service on those days. Passengers travelling from Hoboken to the World Trade Center must take the – to Grove Street and transfer to the Newark–World Trade Center train.

There are currently 13 active PATH stations:

As of 2006, the following is the schedule of fares for the PATH:

• One-Way $1.50 (Cash or MTA Pay-Per-Ride MetroCard. A PATH SingleRide ticket for one-way trips can be purchased from Metrocard Vending machines available in all in PATH stations (No discounts)
• Roundtrip $3.00 (PATH QuickCard or MTA Pay-Per-Ride MetroCard / No discounts)
• Eleven Trip $15.00 (PATH QuickCard Only / Fare discounted to $1.36 per trip)
• Twenty Trip $24.00 (PATH QuickCard Only / Fare discounted to $1.20 per trip)
• Forty Trip $48.00 (PATH QuickCard Only / Fare discounted to $1.20 per trip)
• Senior Citizens $1.00 (Seniors age 65 and older must possess a PATH Senior Fare Card in order to pay the Senior Fare)

PATH QuickCards can be purchased online, from NJ Transit ticket vending machines, and from some private vendors in the vicinity of PATH stations. Single ride PATH tickets, valid for 2 hours from time of purchase, are available from MetroCard Vending Machines inside all PATH stations.^[22]

The Port Authority installed new fare collection turnstiles at all PATH stations in 2005 and 2006. These turnstiles allow passengers to pay their fare with a PATH QuickCard or a MTA Pay-Per-Ride MetroCard — and eventually with a smart card, known as SmartLink. The project is part of a Port Authority project to implement usage of a regional smart card that could be used on transit systems throughout the New York metropolitan area. The new turnstile program first began at the World Trade Center station. PATH QuickCards are still only valid on the PATH rail system.

In the fall of 2005, PATH and the MTA installed a number of MetroCard Vending Machines (MVM) on the concourse at the World Trade Center station and at the 30th Street entrance of the 33rd Street station. These machines sell Pay-Per-Ride MetroCards and will allow people to refill SmartLink cards once they are introduced in 2007. In addition, these machines sell SingleRide PATH tickets for use only on the PATH system. By the 2nd quarter of 2006 MVMs were installed in all PATH stations.

Starting with the week of July 2, 2007 PATH commenced an initial roll out of the SmartLink card to the general public at the World Trade Center station. On July 23, 2007 the card was introduced at the 33rd Street terminal. On August 6, 2007 the card was introduced at the Hoboken terminal. Vending machines have been installed at terminal stations that sell an 11 trip SmartLink card. The cost of the card is $20 which includes an 11 ride fare of $15 plus a $5 charge for the card. The cards can be registered for replacement (at a $5 fee) if lost or stolen.^[23]In the initial stage, the SmartLink card will allow riders to place the same value on it as if they were purchasing a QuickCard by using machines located in PATH stations. A later stage will allow the rider to register the card to be automatically be refilled if the value on the card reaches a pre-set minimum.^{[citation needed]}

As of November 30, a NJ Transit Ticket machine which sold PATH 20 and 40 trip QuickCards as well as Hudson-Bergen Light Rail tickets and was located on the mezzanine level at the Pavonia-Newport station was removed. It was replaced the week of December 10, 2007 by a machine that sells 11 trip SmartLink cards. Similar machines located at the 33rd Street terminal have stickers placed on them indicating that they will be removed in December 2007.

The initial testing phase noted above has been delayed several times due to software problems. It was originally intended to start in August 2006 and then was postponed to October 2006. Continuing problems have moved the testing phase using Senior SmartCards to February 2007.

All terminals (33rd Street, Hoboken, World Trade Center, Journal Square and Newark) are wheelchair accessible, as are Exchange Place and Pavonia/Newport. The Port Authority's 2007-2016 Capital Plan has allocated over $17 million to renovate Grove Street, with a little over $750,000 allocated for 2007. The renovation will include compliance with the Americans with Disabilities Act of 1990. When completed, only five stations, Harrison in New Jersey and four stations along Sixth Avenue in New York City, will not be accessible to the disabled.

PATH has a fleet of 333 cars that are in active revenue service. There are 4 models: PA1, PA2, PA3 and PA4. PATH cars are 51 ft (15.5 m) long, with a width of approximately 9'-2 3/4" (2.8 m). They can achieve a maximum speed of 70 mph (112 km/h). Each car seats 35 passengers, on seats that line the sides of the cars.

The PA1 was built by St. Louis Car in 1965. PA2 cars were built in 1966-67, also by St. Louis. Hawker Siddeley built the PA3 cars in 1972. The PA4s were built by Kawasaki Heavy Industries in 1986-88.

PA1, PA2, and PA3 cars have painted aluminum bodies, and have two doors on each side. Back-lit panels above the doors display the destination of that particular train: HOB for Hoboken, JSQ for Journal Square, NWK for Newark, 33 for 33rd Street, and WTC for World Trade Center. (Some of the older PA3 signs contain such overzealous punctuation as J.S.Q., N.W.K. and 33RD. ST.). The MBTA's Blue and Orange Line cars, built in 1978-79 and 1980-81 respectively are based on the PA3.

PA4 cars have stainless steel bodies, and have three doors on each side. These are the newest cars in the current fleet. Back-lit displays above the windows (between the doors) display the destination of that particular train.

In 1972, PATH revived the tradition of naming its passenger cars. Each car is named after a community whose residents rely on PATH service to reach their destinations. Most of the municipalities are in New Jersey, but there are also a few from Rockland County, New York, along with New York City itself. Each end of the interior of a named car features a brushed aluminum plaque bearing the name of the city or town along with a brief history and description of the area "today" (meaning in 1972), followed by the lines "This car is named in honor of (municipality name), one of more than 300 communities whose residents travel on the Port Authority Trans-Hudson interstate rail system."

The Port Authority awarded a $499 million contract to Kawasaki to design and build 340 new PATH cars (tentatively to be called the PA5), which will replace the system's entire aging fleet. With an average age of 33 years, the fleet is the oldest of any operating heavy rail line in the United States. The Port Authority announced that the new cars will be an updated version of MTA's R142A cars, which are currently in service on the New York City Subway's 4 and 6 lines. These new cars are expected to go into service in 2008.^[24]

Notes: All PA1 through PA3 cars were general overhaul by Morrison Knudsen in the mid 1980s. Cars 139, 143, 160, 612, 745, 750, 845 were left under the World Trade Center on 9/11/01 and survived the collapse. They are currently stored out of service and stripped of usable parts.

While the PATH resembles a typical intraurban rapid transit service, it is in fact a railroad under the jurisdiction of the Federal Railroad Administration. PATH continues to be subject to FRA regulations since the line has a connection to the Amtrak mainline near Harrison station. While the PATH does operate under a number of grandfather waivers, it is required to do things not typically seen on American transit systems. Some of these include the proper fitting of grab irons to all PATH rolling stock, the use of federally certified locomotive engineers, and compliance with the federal railroad hours of service regulations.^{[citation needed]}

While the PATH did once share trackage with the Pennsylvania Railroad, this joint running and all interlocking connections to the former rail lines, other than the afore-mentioned Amtrak connection, have been cut. Due to its near-isolation from the national rail network, PATH could potentially end its status as a railroad, however this railroad status might prove valuable if PATH were to extend service along existing rail routes as normally transit lines are required to either run on separate rights of way or time share with FRA railroads.

The PATH shares a similar status with the Staten Island Railway, which is also an FRA railroad running on a somewhat different waiver.^{[citation needed]}

The Port Authority has allocated funds to conduct a feasibility study of extending PATH two miles (3.2 km) south of Newark Penn Station to Newark Liberty International Airport. If the project is deemed to be possible from an engineering, operational, and financial standpoint, the Port Authority would include funding for the project in its Capital Plan. The extension to Newark Airport is estimated to cost $500 million.^[25]

In October 2007, PATH announced that it would be spending $500 million upgrading its signal system to accommodate anticipated growth in ridership. Construction of the new signal system is expected to be completed around 2014. The signals will reduce headways so trains move more efficiently through the system and reduce passenger wait times.^[26]

Trivia sections are discouraged under Wikipedia guidelines. The article could be improved by integrating relevant items and removing inappropriate ones.

• On 33rd Street trains (between 14th Street and 23rd Street) and on Newark trains (between World Trade Center and Exchange Place), a short, zoetrope-like advertisement can be seen in the tunnels.^[27]
• Every year, around Thanksgiving, PATH employees put up and decorate a lit Christmas tree at a switching station in the tunnel used by trains running from 33rd Street and Hoboken into the Pavonia/Newport station. This tradition has continued since the 1950s when a signal operator, Joe Wojtowicz, started hanging a string of Christmas lights in the tunnel. While PATH officials were initially concerned about putting up decorations in the tunnel, they later acquiesced and the tradition continues to this day. After the September 11th, 2001 attacks, a back-lit U.S. flag was put up beside the tree as a tribute to the victims of the attacks.^[28]
• Photography is prohibited on any PATH trains, or stations. A permit must be requested in advance with the Port Authority and the photographer must be accompanied by Port Authority personnel, but enforcement of this rule is spotty.
• PATH is one of the few transit systems which continue to rely on air-operated switch machines and trip stops throughout its entire system. PATH has found their performance and reliability to be superior in the wet environment of their tunnels and low-lying surface trackage.
• PATH trains and stations have occasionally been the setting for music videos, commercials, and TV programs, sometimes as a stand-in for the New York City Subway. Notable examples are the video for the White Stripes's song "The Hardest Button to Button,"^[29] the Law & Order: Special Victims Unit episode "Control," and the Law & Order episode "Tabula Rasa."
• PATH management has two principal passenger outreach initiatives: the "PATHways" newsletter, distributed free at terminals, and the Patron Advisory Committee.^[30][31]
