Corridor

Gist

A corridor is a long narrow passage in a building or train, with doors that open into rooms, etc.

Details

A hallway (also passage, passageway, corridor or hall) is an interior space in a building that is used to connect other rooms. Hallways are generally long and narrow.

Hallways must be sufficiently wide to ensure buildings can be evacuated during a fire, and to allow people in wheelchairs to navigate them. The minimum width of a hallway is governed by building codes. Minimum widths in residences are 36 inches (910 mm) in the United States. Hallways are wider in higher-traffic settings, such as schools and hospitals.

In 1597 John Thorpe is the first recorded architect to replace multiple connected rooms with rooms along a corridor each accessed by a separate door.

Quebec City–Windsor Corridor (Via Rail)

The Quebec City–Windsor Corridor (French: Ligne de Québec à Windsor), also known as simply the Corridor, is a Via Rail passenger train service in the Canadian provinces of Quebec and Ontario. The Corridor service area has the heaviest passenger train frequency in Canada and contributes 67% of Via's revenue.

History

Prior to Via's formation in 1978, Canadian National Railway operated its passenger trains, branded Rapido, on the same tracks and Canadian Pacific Railway (now Canadian Pacific Kansas City) also offered limited service.

High-speed proposal

During the 1970s and early 1980s, CN and later Via Rail operated the Turbo Train on existing freight rail trackage. This equipment was later replaced by the Bombardier LRC (Light, Rapid, Comfortable) train sets. Beginning in the 1980s and through the 1990s, Via Rail, Bombardier and the provincial and federal governments studied the feasibility of establishing a dedicated high-speed passenger rail network linking Quebec City–Montreal–Ottawa–Toronto–Windsor similar to the French TGV as a means of reducing domestic air and highway travel between these destinations.

After a hiatus of ten years, a feasibility study on launching a high-speed rail service in the Corridor will be updated at the joint cost of the federal government, Ontario and Quebec. On November 14, 2011, the three governments officially released the final report of a high-speed rail study for this corridor.

2009–2010 improvements

In 2009–2010, Via used CA$300 million of government stimulus money to upgrade segments of the Corridor. Notable track improvements were 70 km (43 mi) of additional third main track in four segments, and a short segment of fourth main track, as well as additional yard tracks at three locations. Improvements were made to several stations along the line, with new station buildings constructed at Belleville and Cobourg, and additional platforms for existing stations at Brockville and Oshawa. The improvements were planned to reduce delays along the route and to allow for a reduction in travel time of up to 30 minutes from end to end. They were intended to allow Via to introduce two new round-trip trains from Toronto to both Montreal and Ottawa without requiring the acquisition of new equipment.

Service:

Inter-city rail

Inter-city service along the Corridor is provided by several different routes connecting the different cities served by the service. There is no single route that travels the entire length of the Corridor from Windsor to Quebec City. Via runs a mix of local-service and express trains in the Corridor. The Corridor service area has the heaviest passenger train frequency in Canada, with 36 Via trains traversing the route daily. About 67% of Via's revenue comes from Corridor routes.

Via trains that start and end within the geographic region of the Quebec City–Windsor Corridor are branded as a part of the Corridor service. Other inter-city trains from outside the Corridor may have their terminus at stations in the Corridor, such as the Canadian and the Ocean, but are marketed by their respective train names and are not considered to be Corridor services.

The Maple Leaf, a through service from Toronto to New York City, operated jointly with Amtrak, is crewed by Via as trains 97 and 98 on Via schedules, between Toronto and Niagara Falls, and can be considered part of Corridor services as well. It is the only scheduled rail service from the Corridor line from Burlington to Niagara Falls.

Commuter rail

Two commuter rail agencies, GO Transit and Exo, share tracks with Via's Corridor trains. Both agencies are provincially funded and independent of Via.

* The GO Transit Kitchener line shares tracks with Via trains for its entire route from Toronto Union Station to Kitchener station and a pilot to London station.
* The GO Transit Lakeshore West line shares tracks with Via trains from Toronto Union Station to Bayview junction, just west of Aldershot GO Station. The Lakeshore West line Niagara Branch shares tracks with Via trains for its entire route from Toronto Union Station to Niagara Falls.
* The GO Transit Lakeshore East line shares tracks with Via trains from Toronto Union Station to Durham Junction, just west of Pickering GO Station. Between Pickering and Oshawa, GO trains use a separate parallel line immediately north of the CN/Via tracks.
* The Exo Mont-Saint-Hilaire line shares tracks with Via trains for its entire route from Montreal Central Station to Mont-Saint-Hilaire.
* The Exo Vaudreuil-Hudson line operates in the same corridor as Via trains from Dorion to Lachine, but does not share tracks with Via trains. Exo trains operate on CPKC tracks, while Via trains operate on parallel CN tracks.

Trackage

Most of the trackage that Via trains use along the Corridor is owned by the Canadian National Railway. Via owns three former freight lines long the Corridor, one from Smiths Falls to Coteau-du-Lac, Quebec, via Ottawa; one from Smiths Falls to Brockville; and one from Chatham, Ontario, to Windsor, Ontario. Via Corridor trains run on three segments of tracks owned by Metrolinx; one from Burlington, Ontario, to Pickering, Ontario; one from Toronto Union Station to Malton, Mississauga; and one from Georgetown, Ontario, to Kitchener, Ontario. The proposed High Frequency Rail plan calls for adding Corridor services between Toronto and Quebec City that run on newly constructed dedicated tracks.

Future

On July 6, 2021, Transportation Minister Omar Alghabra announced that the federal government would launch the procurement process to build a high-frequency rail corridor between Toronto and Quebec City by 2030. The cost of the project was expected to be between $6 billion and $12 billion. The plan is to have trains travel up to 200 km/h (125 mph) on a line that would run from Toronto to Quebec City through Peterborough, Ottawa, Montreal, Laval, and Trois-Rivières. As opposed to current operations along the Corridor, the trains would run on dedicated passenger tracks, improving service reliability since the trains would not have to compete with freight trains. Service reliability could increase to 95 percent, up significantly from its 2021 rate of 67 percent. Travel times are projected to decrease by 90 minutes on some routes, such as between Ottawa and Toronto. 90 percent of the route is planned to be electrified. The timing of the announcement was criticized as political, since there was speculation of a federal election being held later in the year, which was later confirmed on August 15.

In July 2023, the government selected three consortia to proceed to the request-for-proposals stage:

* Cadence: CDPQ Infra, SNC-Lavalin, Systra and Keolis
* Intercity Rail Developers: Intercity Development Partners, EllisDon, Kilmer Transportation, Jacobs, Hatch, CIMA+, FirstGroup, RATP and Renfe
* QConnexiON Rail Partners: Fengate, John Laing, Bechtel, WSP and Deutsche Bahn.

Ramanathaswamy Temple

The Ramanathaswamy Temple (Rāmanātasvāmi Kōyil) is a Hindu temple dedicated to the Hindu god Shiva located on Rameswaram island in the state of Tamil Nadu, India. It is one of the twelve Jyotirlinga temples. It is one of the 275 Paadal Petra Sthalams, the sacred sites glorified by the Nayanars (Shaivite poet-saints), Appar, Sundarar, and Sambandar, with their songs. According to tradition, the lingam (an aniconic form of Shiva) of the Ramanathaswamy Temple was established and worshipped by Rama before he crossed the bridge called Rama Setu to the island kingdom of Lanka, identified with Sri Lanka. It is one of the Char Dham pilgrimage sites. The temple was expanded during the 12th century by the Pandya Dynasty, and its principal shrine’s sanctum was renovated by Jeyaveera Cinkaiariyan and his successor Gunaveera Cinkaiariyan, monarchs of the Jaffna kingdom. The temple has the longest corridor among all the Hindu temples of India. It was built by King Muthuramalinga Sethupathy. The temple is considered a pilgrimage site for Shaivites, Vaishnavites, and Smartas.

The temple is one of the most famous pilgrimage sites and has several historical references about it. The Maratha kings who ruled Thanjavur established chatrams or rest houses throughout Mayiladuthurai and Rameswaram between 1745 and 1837 CE and donated them to the temple.

The outer set of corridors is reputed to be the longest in the world, measuring about 6.9 m in height, 400 feet each in the east and west and about 640 feet in the north and the south. The inner corridors are about 224 feet each in the east and the west and about 352 feet each in the north and the south.

Like all ancient temples in South India, there is a high compound wall (madil) on all four sides of the temple premises measuring about 865 feet furlong from east to west and one furlong of 657 feet from north to south with huge towers (Gopurams) to the east and the west and finished gate towers to the north and south. The temple has striking long corridors in its interior, running between huge colonnades on platforms above five feet high.

The second corridor is formed by sandstone pillars, beams, and ceiling. The junction of the third corridor on the west and the paved way leading from the western gopuram to the Setumadhava shrine forms a unique structure in the form of a chess board, popularly known as Chokkattan Madapam, where the Utsava deities are adorned and kept during the Vasanthotsavam (Spring festival) and on the 6th day festival in Adi (July–August) and Masi (February–March) conducted by the Sethupathi of Ramnad.

The outer set of corridors is reputed to be the longest in the world, measuring about 6.9 m in height, 400 feet each in the east and west and about 640 feet in the north and the south. The inner corridors are about 224 feet each in the east and the west and about 352 feet each in the north and the south. Their width varies from 15.5 feet to 17 feet in the east and west about 172 feet on the north and south with width varying 14.5 feet to 17 feet. The total length of these corridors is thus 3850 feet. There are about 1212 pillars in the outer corridor. Their height is about 30 feet from the floor to the center of the roof. The main tower or rajagopuram is 53 m tall. Most pillars are carved with individual compositions. At the beginning, Ramanathaswamy Temple was a thatched shed. The present structure was the work of many individuals spread over a number of centuries. The pride of place in the establishment of the Temple goes to the Setupatis of Ramanathapuram. In the seventeenth century, Dalavai Setupati built a portion of the main eastern Gopuram. In the late eighteenth century, the world-famous third corridor was constructed by Muthuramalinga Setupati who lived for forty-nine years and ruled between 1763 and 1795. The corridor was called "Chokkatan Mandapam". The Mukhya Pradhani (Chief Minister) was Muthuirullappa Pillai and the Chinna Pradhani (Deputy Chief Minister) was Krishna Iyengar. The Setupati's statue and those of his two Pradhanis (ministers) can be seen at the western entrance to the third corridor.

The composite columns of Virabhadra holding sword and horn are found be additions of the Vijayanagara kings during the early 1500s. Similar columns of Virabhadra are found in Adikesava Perumal Temple at Thiruvattaru, Meenakshi Temple at Madurai, Nellaiappar Temple at Tirunelveli, Kasi Viswanathar temple at Tenkasi, Krishnapuram Venkatachalapathy temple, Soundararajaperumal temple at Thadikombu, Srivilliputhur Andal temple, Srivaikuntanathan Permual temple at Srivaikuntam, Avudayarkovil, Vaishnava Nambi and Thirukurungudivalli Nachiar temple at Thirukkurungudi.

There are separate shrines for Ramanathaswamy and his consort goddess Parvathavardhini separated by a corridor. There are separate shrines for the goddess Vishalakshi, the utsava images, sayanagriha, Vishnu and Ganesha. The samadhi of the great Yogi Patanjali is said to be at this temple and there is a separate shrine for him here. There are various halls inside the temple, namely Anuppu Mandapam, Sukravara Mandapam, Setupati Mandapam, Kalyana Mandapam, and Nandi Mandapam.
