102-693: Queen Elizabeth Olympic Park is a sporting complex and public park in Stratford , Hackney Wick , Leyton and Bow , in east London . It was purpose-built for the 2012 Summer Olympics and Paralympics , situated adjacent to the Stratford City development. It contains the Olympic stadium , now known as the London Stadium, and the Olympic swimming pool together with the athletes' Olympic Village and several other Olympic sporting venues and

204-476: A dispute with the landlord. The club would merge with Thames Ironworks F.C. , the forerunner of West Ham United F.C. , in 1895. Directly to the south of the churchyard stands a 12.80-metre tall granite obelisk , which was erected in 1861 as a memorial to the Quaker philanthropist and abolitionist , Samuel Gurney (1766 to 1856). The plinth carries two brass drinking fountain heads on opposite sides, with

306-476: A hamlet in the northwest part of the ancient parish of West Ham , as the area urbanised it expanded, increased in population and merged with neighbouring districts. Except as a ward, Stratford has never been a unit of administration and so, like many London districts, lacks formally defined boundaries. As described however, Stratford occupies the north-west part of West Ham and so takes the northwest boundaries of that area; boundaries which have subsequently become

408-570: A large height clearance for navigation. Such towers and the conductors they carry must be equipped with flight safety lamps and reflectors. Two well-known wide river crossings are the Elbe Crossing 1 and Elbe Crossing 2 . The latter has the tallest overhead line masts in Europe, at 227 m (745 ft) tall. In Spain, the overhead line crossing pylons in the Spanish bay of Cádiz have

510-443: A line is constructed using towers designed to carry several circuits, it is not necessary to install all the circuits at the time of construction. Indeed, for economic reasons, some transmission lines are designed for three (or four) circuits, but only two (or three) circuits are initially installed. Some high voltage circuits are often erected on the same tower as 110 kV lines. Paralleling circuits of 380 kV, 220 kV and 110 kV-lines on

612-516: A lower cost than building a new transmission line. Towers used for single-phase AC railway traction lines are similar in construction to those towers used for 110 kV three-phase lines. Steel tube or concrete poles are also often used for these lines. However, railway traction current systems are two-pole AC systems, so traction lines are designed for two conductors (or multiples of two, usually four, eight, or twelve). These are usually arranged on one level, whereby each circuit occupies one half of

714-457: A natural boundary between Essex on the eastern bank and Middlesex on the west, and was a formidable obstacle to overland trade and travel. The name is first recorded in 1067 as Strætforda and means ' ford on a Roman road'. It is formed from Old English 'stræt' (in modern English 'street') and 'ford'. The former river crossing lay at an uncertain location north of Stratford High Street . The district of Old Ford in northern Bow – west of

816-534: A neighbourhood except for Waltham Forest . The park was designed by the EDAW Consortium (including EDAW , Allies and Morrison and Buro Happold ), working with Arup and WS Atkins . Detailed landscape architecture was by LDA Design in conjunction with Hargreaves Associates. LDA design contracted Wallace Whittle to carry out various aspects of the M+E Building services design. The NHBC carried out

918-552: A new home for Newham and Essex Beagles Athletic Club following the 2017 World Championships . Football side Altis FC, members of the Amateur Football Combination , are based at the stadium. In January 2013, music concert promoter Live Nation won the right to stage shows at the stadium and in the surrounding park. The park hosted the music events in July 2013, but the stadium was not used. The former site of

1020-492: A new hotel. The area is accessible via Stratford station . Although the sporting venues in the park were reduced in scale after the conclusion of London 2012, part of the legacy is to ensure the continued use of those facilities that are permanent, as local and community resources and for major international sporting events that make use of the world class facilities constructed for the Olympics and Paralympics: In addition to

1122-674: A particularly interesting construction. The main crossing towers are 158 m (518 ft) tall with one crossarm atop a frustum framework construction. The longest overhead line spans are the crossing of the Norwegian Sognefjord Span (4,597 m (15,082 ft) between two masts) and the Ameralik Span in Greenland (5,376 m (17,638 ft)). In Germany, the overhead line of the EnBW AG crossing of

1224-565: A permanent legacy of the 2012 Summer Olympics. It closed after the end of the Games, but was reopened to the public in April 2014. Built in 1868, as part of the new London sewerage system by Sir Joseph Bazalgette , the building originally housed steam pumps and is a notable example of Italian style Gothic Revival architecture . It is opened to the public on an occasional basis, when the "flamboyant interior of enriched cast ironwork" can be seen. It

1326-451: A ready market for its produce. By the 18th century, the area around Stratford was noted for potato growing, a business that continued into the mid-1800s. Stratford also became a desirable country retreat for wealthy merchants and financiers, within an easy ride of the City . When Daniel Defoe visited Stratford in 1722, he reported it had "...increased in buildings to a strange degree, within

1428-523: A steel plant in Piombino, Italy [4] and on a roof on an industrial building at Cherepovets, Russia at 59°8'52"N 37°51'55"E. Until 2015, on a residential highrise building in Dazhou, China at 31°11'28"N 107°30'43"E a powerline tower stood. Beside this, it is also possible that the lower parts of an electricity pylon stand in a building. Such a structure a person, who cannot have a view of the interior of

1530-429: A variety of ways they can then be assembled and erected: The International Civil Aviation Organization issues recommendations on markers for towers and the conductors suspended between them. Certain jurisdictions will make these recommendations mandatory, for example that certain power lines must have overhead wire markers placed at intervals, and that warning lights be placed on any sufficiently high towers, this

1632-426: A very small footprint and relies on guy wires in tension to support the structure and any unbalanced tension load from the conductors. A guyed tower can be made in a V shape, which saves weight and cost. Poles made of tubular steel generally are assembled at the factory and placed on the right-of-way afterward. Because of its durability and ease of manufacturing and installation, many utilities in recent years prefer

1734-561: Is a 61.3 m (201 ft) tall pylon of a 380 kV powerline near Reuter West Power Plant in Berlin. In China some pylons for lines crossing rivers were built of concrete. The tallest of these pylons belong to the Yangtze Powerline crossing at Nanjing with a height of 257 m (843 ft). Sometimes (in particular on steel lattice towers for the highest voltage levels) transmitting plants are installed, and antennas mounted on

1836-599: Is a memorial to the Stratford Martyrs , who were burned at the stake in 1556 (possibly at Stratford, but more likely at Bow ) during the reign of Queen Mary . The memorial itself is octagonal with terracotta plaques on each face, surmounted by a twelve sided spire. It was unveiled in 1878. St Francis of Assisi Church, Stratford is the Roman Catholic church in Stratford. It was built in 1868 and

1938-479: Is a new commercial district in Stratford, East London , which hosted the London 2012 Olympic and Paralympic Games . It will be a mixed-use development, with a total investment of in excess of £1.3 billion, and will be delivered by Lend Lease and London and Continental Railways in a 50/50 joint venture. Stratford Cross will include 4 million sq ft of commercial office space, 330 homes known as Glasshouse Gardens and

2040-470: Is also used in environments that would be corrosive to steel. The extra material cost of aluminium towers will be offset by lower installation cost. Design of aluminium lattice towers is similar to that for steel, but must take into account aluminium's lower Young's modulus . A lattice tower is usually assembled at the location where it is to be erected. This makes very tall towers possible, up to 100 m (328 ft) (and in special cases even higher, as in

2142-565: Is held by Rokhsana Fiaz since 4 May 2018. In 2018, previous incumbent Sir Robin Wales was de-selected by the Newham Labour Party to be their candidate in the mayoral election, losing to Custom House councillor Rokhsana Fiaz by 861 votes to Wales who had 503. The modern borough has an electoral ward named 'Stratford and New Town'. Most of the 560-acre Queen Elizabeth Olympic Park is located within Stratford, with other parts of

2244-553: Is limited to approximately 30 m (98 ft). Wood is rarely used for lattice framework. Instead, they are used to build multi-pole structures, such as H-frame and K-frame structures. The voltages they carry are also limited, such as in other regions, where wood structures only carry voltages up to approximately 30 kV. In countries such as Canada or the United States, wooden towers carry voltages up to 345 kV; these can be less costly than steel structures and take advantage of

2346-418: Is served by Franciscan Friars . As of the 2011 census, White British is the largest ethnic group in the Stratford and New Town ward, at 21% of the population, followed by Other White at 19% and Black African at 13%; other ethnic groups comprised the remaining 47%. Electricity pylon There are four categories of transmission towers: (i) the suspension tower , (ii) the dead-end terminal tower, (iii)

Following the demolition of the original warm-up track after the end of the Olympics, a new six-lane facility, the London Marathon Community Track , was constructed on the south side of the Olympic Stadium, for use both as a community venue and as

2550-1051: Is the name for the structure used in the industry in the United States and some other English-speaking countries. In Europe and the U.K., the terms electricity pylon and pylon derive from the basic shape of the structure, an obelisk with a tapered top. In Canada, the term hydrotower is used, because hydroelectricity is the principal source of electricity for the country. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines. In some European countries, e.g. Germany, Spain or Czech Republic, smaller lattice towers are used for medium voltage (above 10 kV) transmission lines too. The towers must be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses (wooden structures are used in Australia, Canada, Germany, and Scandinavia in some cases) and

2652-461: The Elbe crossing 1 and Elbe crossing 2 ). Assembly of lattice steel towers can be done using a crane . Lattice steel towers are generally made of angle-profiled steel beams (L-beam or T-beams ). For very tall towers, trusses are often used. Wood is a material which is limited in use in high-voltage transmission. Because of the limited height of available trees, the maximum height of wooden pylons

2754-455: The Hamburg water and navigation office. For crossing broad valleys, a large distance between the conductors must be maintained to avoid short-circuits caused by conductor cables colliding during storms. To achieve this, sometimes a separate mast or tower is used for each conductor. For crossing wide rivers and straits with flat coastlines, very tall towers must be built due to the necessity of

2856-694: The London Olympics Media Centre . The park is overlooked by the ArcelorMittal Orbit , an observation tower and Britain's largest piece of public art. It was simply called The Olympic Park during the Games but was later renamed to commemorate the Diamond Jubilee of Queen Elizabeth II (though it is not an official Royal Park of London ). The park occupies an area straddling four east London boroughs; Newham , Tower Hamlets , Hackney and Waltham Forest . Part of

Stratford grew rapidly in the 19th century after the railway came to the area in 1839, forming part of the conurbation of London , similar to much of south-west Essex. The late 20th century was a period of severe economic decline in

3162-422: The tension tower , and (iv) the transposition tower . The heights of transmission towers typically range from 15 to 55 m (49 to 180 ft), although when longer spans are needed, such as for crossing water, taller towers are sometimes used. More transmission towers are needed to mitigate climate change , and as a result, transmission towers became politically important in the 2020s. Transmission tower

3264-477: The "white" space between the venue construction zones, including managing the internal road network. To enable the major phase of construction to begin, the 52 electricity pylons , up to 65 metres (213 feet) high, that dominated the landscape in and around the park were removed and the power transferred through the new Lower Lea Valley Cable Tunnels constructed by Murphy. Also there was a Roman village underground when they were digging it up Following site clearance,

The level of industrialisation experienced by the parish and borough of West Ham led to it becoming known as the Factory centre of the south of England . Stratford was the base the greatest concentration of manufacturing activity within West Ham. Stratford was originally an agricultural community, whose proximity to London provided

3468-667: The 20th century. This was compounded by the closing of the London Docks in the 1960s. Around this time, the Stratford Shopping Centre was built, beginning efforts to guide the area through the process of transformation from a working-class industrial and transport hub to a retail and leisure destination for the contemporary age. These efforts continued with the Olympic bid for Stratford, and the ongoing urban regeneration work going on there. Stratford began as

3570-629: The Bow), eventually became known simply as Bow , while over time the eastern Stratford lost its "Langthorne" suffix. The bridge was repaired and upgraded many times over the centuries until eventually demolished and replaced in the 19th century. In 1135 the Cistercian Order founded Stratford Langthorne Abbey , also known as West Ham Abbey. This became one of the largest and most wealthy monasteries in England, owning 1,500 acres (610 hectares) in

3672-483: The ECR at Stratford on 15 September 1840. A railway works and depot for engines and rolling stock was established by Great Eastern in 1847 to the north of Stratford. At its peak, the works employed over 2,500, many of whom had homes, along with other railway workers, in the town that developed nearby. It was originally called Hudson Town, after George Hudson , the "Railway King", but after his involvement in bribery and fraud

3774-782: The Eyachtal has the longest span in the country at 1,444 m (4,738 ft). In order to drop overhead lines into steep, deep valleys, inclined towers are occasionally used. These are utilized at the Hoover Dam , located in the United States, to descend the cliff walls of the Black Canyon of the Colorado . In Switzerland, a pylon inclined around 20 degrees to the vertical is located near Sargans , St. Gallens . Highly sloping masts are used on two 380 kV pylons in Switzerland,

In 1914, the first year of World War One , the pub was renamed in honour of the preceding king, Edward VII who had died in 1910. The old name was problematic as 'The King of Prussia' was one of the titles of the German Emperor, Kaiser Wilhelm II . More than a hundred years later,

3978-830: The King Edward VII pub is still locally nicknamed 'The Prussian'. A 38 tonne 0-6-0 saddle-tank steam locomotive named Robert is displayed in Meridian Square, the forecourt of Stratford Station. It was built in 1933 by the Avonside Engine Company of Bristol for use at the Lamport Ironstone mines railway near Brixworth , Northamptonshire. It was previously an exhibit at the North Woolwich Old Station Museum , but moved to Stratford in 1999. In 2008, it

5304-646: The country. The site of the factory was to the north of Stratford High Street near the modern Bow Flyover; it was the subject of archaeological excavations in 1921 and 1969. The Victorian era saw growth hugely accelerated by three major factors: the Metropolitan Building Act , the arrival of the railway and the creation of the nearby Royal Docks . Rapid growth followed the Metropolitan Building Act of 1844, which restricted dangerous and noxious industries from operating in

5406-488: The cross arm. For four traction circuits, the arrangement of the conductors is in two levels and for six electric circuits, the arrangement of the conductors is in three levels. Transmission towers must withstand various external forces, including wind, ice, and seismic activity, while supporting the weight of heavy conductors. Different shapes of transmission towers are typical for different countries. The shape also depends on voltage and number of circuits. Delta pylons are

5508-417: The decision and eventually the deal with West Ham collapsed due to legal pressure on 11 October 2011. West Ham did go on to win the later tenancy bid and began using the stadium from the start of the 2016–17 football season as the main tenant. The Copper Box was the only permanent indoor arena remaining after the end of London 2012. Built primarily for use in the handball and goalball competitions, it

5610-489: The decision to allow West Ham to relocate to the stadium, as he believed that having West Ham playing within one mile (1.6 kilometres) of their Brisbane Road stadium could cost Orient support and even their existence. Incidentally, Hearn had expressed interest some years earlier in moving Orient to Olympic Park and reducing its capacity to 25,000 seats, while West Ham would cut the capacity to 60,000 if their relocation went ahead. Tottenham Hotspur also pursued legal action over

The industrialisation of Stratford started slowly and accelerated rapidly in the early Victorian era. The Stratford and national experience of the Industrial Revolution inspired scenes in the 2012 Olympic Opening Ceremony covering the traumatic transition from a 'Green and Pleasant Land' to

6018-440: The ground. A semi-flexible tower is designed so that it can use overhead grounding wires to transfer mechanical load to adjacent structures, if a phase conductor breaks and the structure is subject to unbalanced loads. This type is useful at extra-high voltages, where phase conductors are bundled (two or more wires per phase). It is unlikely for all of them to break at once, barring a catastrophic crash or storm. A guyed mast has

Bog Fox is a design pylon in Estonia south of Risti at 58° 59′ 33.44″ N, 24° 3′ 33.19″ E. In Russia several pylons designed as artwork were built [6] Before transmission towers are even erected, prototype towers are tested at tower testing stations . There are

6222-523: The highest arm has each one cable, the second has two cables and the third has three cables on each side. The cables on the third arm usually carry circuits for lower high voltage. Special designed pylons are necessary to introduce branching lines, e.g. to connect nearby substations. Towers may be self-supporting and capable of resisting all forces due to conductor loads, unbalanced conductors, wind and ice in any direction. Such towers often have approximately square bases and usually four points of contact with

In 1110 Matilda , wife of Henry I , ordered a distinctively bow-shaped (arched) bridge to be built over the River Lea, together with a causeway across the marshes along the line now occupied by Stratford High Street. Reports state she (or her retinue) encountered problems crossing the river to get to Barking Abbey . The western Stratford then become suffixed by "-atte-Bow" (at

7242-540: The most common design for single circuit lines, because of their stability. They have a V-shaped body with a horizontal arm on the top, which forms an inverted delta . Larger Delta towers usually use two guard cables. Portal pylons are widely used in the USA, Ireland, Scandinavia and Canada. They stand on two legs with one cross arm, which gives them a H-shape. Up to 110 kV they often were made from wood, but higher voltage lines use steel pylons. Smaller single circuit pylons may have two small cross arms on one side and one on

7344-721: The northwest boundary of the modern London Borough of Newham . In this way the River Lea and the complex network of the Bow Back Rivers mark the western limits of the area, which also extends north as far as the boundary of the London Borough of Waltham Forest . Most of Stratford is in the E15 postal area, however the Royal Mail has given the new E20 postcode to the Olympic Park and Stratford City developments; this

7446-494: The other. One level pylons only have one cross arm carrying 3 cables on each side. Sometimes they have an additional cross arm for the protection cables. They are frequently used close to airports due to their reduced height. Danube pylons or Donaumasten got their name from a line built in 1927 next to the Danube river . They are the most common design in central European countries like Germany or Poland. They have two cross arms,

7548-468: The park and Stratford City the postcode E20 , which had previously only appeared in the television soap opera EastEnders for the fictional suburb of Walford . On 2 August 2011, it was announced the five neighbourhoods of housing and amenities (anti-clockwise from north-east) are: These names have relevant history in the area. All four of the East London boroughs covering the park as such have

7650-480: The park have been built on, replaced by cultural and commercial premises, as well as new housing. Stratford Park on West Ham Lane was laid out, in stages, by the County Borough of West Ham between 1899 and 1912. It was originally called West Ham Recreation Ground and is still known to many as West Ham Rec . The name was changed in 1999 to avoid confusion with nearby West Ham Park . In 1892–93, before

7752-403: The park in the London Borough of Tower Hamlets , the London Borough of Hackney and the London Borough of Waltham Forest . The park was prepared as the main venue of the 2012 Summer Olympics and permanently opened to the public in 2014. As part of the games and its legacy, the park included a number of sporting venues as well as extensive open spaces. Since the games many of the open parts of

7854-532: The park reopened in July 2013, while a large majority of the rest (including the Aquatics Centre, Velopark and Orbit observation tower) reopened in April 2014. The site covers parts of Stratford , Bow , Leyton , and Hackney Wick in east London , overlooking the A12 road . The site was previously a mixture of greenfield and brownfield land, including parts of Hackney Marshes . The Royal Mail gave

7956-558: The pleasure and health of the latter part of their days". An early industrial undertaking at Stratford was the Bow porcelain factory , which despite the name, was on the Essex side of the River Lea. Using a process that was patented in 1744, Edward Heylin and Thomas Frye operated a factory near Bow Bridge called "New Canton" to produce some of the first soft-paste porcelain to be made in

8058-583: The pole in use. In the latter case, the line from the converter station to the earthing (grounding) electrode is built as underground cable, as overhead line on a separate right of way or by using the ground conductors. Electrode line towers are used in some HVDC schemes to carry the power line from the converter station to the grounding electrode. They are similar to structures used for lines with voltages of 10–30 kV, but normally carry only one or two conductors. AC transmission towers may be converted to full or mixed HVDC use, to increase power transmission levels at

8160-737: The public grid or for the railway traction current grid. Concrete poles for medium-voltage are also used in Canada and the United States. In Switzerland, concrete pylons with heights of up to 59.5 metres (world's tallest pylon of prefabricated concrete at Littau ) are used for 380 kV overhead lines. In Argentina and some other south american countries, many overhead power lines, except the ultra-high voltage grid, were placed on tubular concrete pylons. Also in former soviet countries, concrete pylons are common, though with crossarms made of steel. Concrete pylons, which are not prefabricated, are also used for constructions taller than 60 metres. One example

8262-454: The pylons in order to prevent electrochemical corrosion of the pylons. For single-pole HVDC transmission with ground return, towers with only one conductor can be used. In many cases, however, the towers are designed for later conversion to a two-pole system. In these cases, often conductors on both sides of the tower are installed for mechanical reasons. Until the second pole is needed, it is either used as electrode line or joined in parallel with

8364-455: The realization of overhead 400/230 volt grids for the power supply of homes [1] . However, there are also roof-mounted support structures for high-voltage. Some thermal power plants in Poland like Połaniec Power Station and in the former Soviet Union like Lukoml Power Station use portal pylons on the roof of the power station building for the high voltage line from the machine transformer to

8466-516: The same towers is common. Sometimes, especially with 110 kV circuits, a parallel circuit carries traction lines for railway electrification . High-voltage direct current (HVDC) transmission lines are either monopolar or bipolar systems. With bipolar systems, a conductor arrangement with one conductor on each side of the tower is used. On some schemes, the ground conductor is used as electrode line or ground return. In this case, it had to be installed with insulators equipped with surge arrestors on

8568-469: The same width. In 2021 the first T-pylon, a new tubular T-shaped design, was installed in United Kingdom for a new power line to Hinkley Point C nuclear power station , carrying two high voltage 400 kV power lines. The design features electricity cables strung below a cross-arm atop a single pole which reduces the visual impact on the environment compared to lattice pylons. These 36 T-pylons were

8670-516: The second most significant business location in east London after Canary Wharf . Stratford's early significance was due to a Roman road (later known as the Great Essex Road ) running from Aldgate in the City , across the River Lea , to Romford , Chelmsford and Colchester . At that time the various branches of the river were tidal and without channels, while the marshes surrounding them had yet to be drained. The Lea Valley formed

8772-500: The soil across the Park site was cleaned down to a human health layer, by soil washing. In addition, at the time of the Olympic and Paralympic games: The park has been given over to a number of current and planned uses after the London 2012 Summer Olympics finished, such as: As of January 2021, several arts and creativity institutions are constructing outposts at the park as part of a £1.1billion development, including: Stratford Cross

8874-559: The surge voltage insulating properties of wood. As of 2012 , 345 kV lines on wood towers are still in use in the US and some are still being constructed on this technology. Wood can also be used for temporary structures while constructing a permanent replacement. Concrete pylons are used in Germany normally only for lines with operating voltages below 30 kV. In exceptional cases, concrete pylons are used also for 110 kV lines, as well as for

8976-519: The switchyard. Also other industrial buildings may have a rooftop powerline support structure. One can find such a device at a steel work in Dnipro, Ukraine at 48°28'57"N 34°58'43"E and at a steel work in Freital, Germany at 50°59'53"N 13°38'26"E. In the United States such device may be more common as in other countries [2] , [3] There are also real rooftop high voltage towers on industry buildings as at

9078-442: The top 32 meters of one of them being bent by 18 degrees to the vertical. Power station chimneys are sometimes equipped with crossbars for fixing conductors of the outgoing lines. Because of possible problems with corrosion by flue gases, such constructions are very rare. There exist also a variety of pylons and powerline poles mounted on buildings. The most common forms are small rooftop poles used in some countries like Germany for

9180-412: The top above or below the overhead ground wire . Usually these installations are for mobile phone services or the operating radio of the power supply firm, but occasionally also for other radio services, like directional radio. Thus transmitting antennas for low-power FM radio and television transmitters were already installed on pylons. On the Elbe Crossing 1 tower, there is a radar facility belonging to

9282-416: The upper arm carries one and the lower arm carries two cables on each side. Sometimes they have an additional cross arm for the protection cables. Ton shaped towers are the most common design, they have 3 horizontal levels with one cable very close to the pylon on each side. In the United Kingdom the second level is often (but not always) wider than the other ones while in the United States all cross arms have

9384-469: The use of monopolar steel or concrete towers over lattice steel for new power lines and tower replacements. In Germany steel tube pylons are also established predominantly for medium voltage lines, in addition, for high voltage transmission lines or two electric circuits for operating voltages by up to 110 kV. Steel tube pylons are also frequently used for 380 kV lines in France , and for 500 kV lines in

9486-517: The use of the venues for international events, some of them are intended for use on a regular basis by amateur and professional sports teams in various sports. On 11 February 2011, West Ham United were selected as preferred bidders, ahead of Tottenham Hotspur , to take over the Olympic Stadium as a football venue after the end of the games. However, five days later Leyton Orient chairman Barry Hearn announced that he would be challenging

9588-484: The world), increased Stratford's importance as a transport and manufacturing centre. Rising population levels led to two major new Anglican churches in the area, St John's Church in 1834 and Christ Church in 1851. Stratford station was opened on 20 June 1839 by the Eastern Counties Railway (ECR). The Northern and Eastern Railway opened a section of its authorised line from Broxbourne to join

9690-845: Was also cancelled, with the fencing events taking place at ExCeL London . The remaining indoor arenas are the Basketball Arena and the Copper Box , in addition to the Water Polo Arena , the Aquatics Centre , and the Velopark . The final design of the park was approved by the Olympic Delivery Authority and its planning-decisions committee. The Legacy List is the independent charity for Queen Elizabeth Olympic Park, set up in 2011 to support

9792-846: Was converted to a multi-use venue that will include use for basketball . As a result of the owners of the Prestige Homes Arena in Milton Keynes terminating their lease, the London Lions basketball club, after a season at the National Sports Centre , Selhurst , relocated to the Copper Box for the 2013-14 BBL season . The Lee Valley Hockey Centre was born from a revamp of the Olympic Legacy Hockey Facility . The facility

9894-595: Was erected on the marshy wastes of Stratford and Plaistow, and it only required the construction at Canning Town of the Victoria and Albert Docks to make the once desolate parish of West Ham a manufacturing and commercial centre of the first importance and to bring upon it a teeming and an industrious population." By the early 19th century, Stratford was an important transport hub, with omnibuses and coaches running into London four times every hour and coaches from East Anglia passing through hourly. The route into London

9996-564: Was moved on to the East Anglia Railway Museum at Chappel and Wakes Colne railway station near Colchester ; there it was cleaned and repainted at the expense of the Olympic Delivery Authority and returned to Stratford in 2011. A 114-metre-tall (374 ft) sculpture and observation tower in the Queen Elizabeth Olympic Park. It is Britain's largest piece of public art and is intended to be

10098-598: Was plied by Walter Hancock 's steam coaches for a period during the 1830s. A small dock and a number of wharves were operating on the River Lea at Stratford by the 1820s, serving the needs of local industries. The opening of the Victoria Dock (later Royal Victoria Dock ) nearby on the Thames in 1855, and the subsequent construction of the Royal Group of Docks (at one time the largest area of impounded water in

10200-608: Was previously only used by the BBC TV soap EastEnders for its fictional East London setting of Walford . The name "Walford" is a portmanteau of the names of nearby Walthamstow and Stratford itself. Stratford was one of three ancient wards in the large ancient parish of West Ham , in the Becontree hundred of Essex . It came within the Metropolitan Police District in 1840. Despite forming part of

10302-534: Was revealed in 1849, the settlement quickly became better known as Stratford New Town , which by 1862 had a population of 20,000. During the lifetime of the Stratford works, 1,682 locomotives , 5,500 passenger coaches and 33,000 goods wagons were built. The last part of the works closed in March 1991. Stratford, like many areas of London, particularly in the East End, suffered significant de-industrialisation in
