Canary Wharf railway station, designed by Foster + Partners, is currently under construction in Canary Wharf, east London, as part of the Crossrail project. Construction began in May 2009, its above-ground floors (containing services and retail units, topped by a roof garden) opened in 2016, and is expected to start receiving railway services in 2018. During the project's development the station was named Isle of Dogs, before the current name was adopted. Construction will cost an estimated £500 million to complete. The design includes Crossrail Place, a roof garden.
The station will be one of the largest on the Crossrail route, which will be branded as the Elizabeth Line from 2018. The station will be situated between Whitechapel and Custom House and it will provide an interchange with Canary Wharf tube station on the London Underground and Poplar DLR station on the Docklands Light Railway.
The station is located beneath and within the West India North Dock. The station will extend from east of the Docklands Light Railway bridge to the east end of the dock. It stands within a 475-metre (1,558 ft) long concrete box with a 245-metre (804 ft) long island platform. It is fitted out to 210 m (690 ft) with the potential for extension should the need to operate longer trains arise. A 165-metre (541 ft) long scissor crossover at the western end of the station will enable trains to either terminate at Canary Wharf and turn back towards central London, or to continue to the terminus at Abbey Wood.
The main access point for the Crossrail station was to be the rebuilt Great Wharf Bridge. From this entrance there would have been a set of escalators to the concourse level, which will be located underwater. Another bank of escalators would take passengers to the platforms.
Construction of the station was to predominantly take place on Hertsmere Road, which runs parallel to the West India North Dock. This would have involved digging a 9 m (30 ft) wide shaft to the station depth of 30 m (98 ft) below the dock water-level to enable crew and equipment to begin boring the box that will form the station. The construction including fit-out and commissioning of the Hertsmere Road shaft was expected to take approximately four years whilst the same would take five years for the station.
In December 2008 an extra £150 million of funding from the Canary Wharf Group was announced for the station. Work was due to commence in January 2009. As part of the deal Canary Wharf Group substantially redesigned the station, incorporating a large shopping centre and a park above the platforms situated in the middle of the dock.
A groundbreaking ceremony for the station was held on 15 May 2009. It was also announced that the station would be named Canary Wharf, and not Isle of Dogs as initially planned.
Throughout 2009 the main focus was on installing 293 interlocking steel piles 18.5 m (61 ft) high and 1.2 m (3 ft 11 in) wide into the dock floor using ten-storey high piling cranes and Giken piling machines to form a cofferdam. As part of this, 38 m (125 ft) deep reinforced concrete piles were placed through each of the 293 tubes. A further 160 temporary anchor piles and ties were installed to provide restraint for the cofferdam wall.
On 11 February 2010 Sadiq Khan, then Transport Minister, activated pumps designed to drain nearly 100 million litres (22,000,000 imp gal; 26,000,000 US gal) from the work site over the following six weeks. The pumps transferred water from inside the site's specially constructed cofferdam to the North Dock at a maximum rate of 13,500 litres (3,000 imp gal; 3,600 US gal) per minute.
A station 'box' was constructed in a dry environment in a similar technique to that used in the construction of the nearby Canary Wharf tube station. Crossrail Place is the structure above the platforms and was partly opened on 1 May 2015. In September 2015, the station construction was completed and the focus has shifted to fitting the station screen doors, ticket machines and other things before the station is scheduled for opening in 2018.
The station will provide connection to the Docklands Light Railway at Poplar and the London Underground at Canary Wharf. It will also have indirect interchanges with Canary Wharf DLR station and West India Quay DLR station. The station will be served by London Buses routes 277, D7, D8, D3 135 and night route N550 at Cabot Square.
