Canary Wharf railway station

Canary Wharf is a future railway station in Canary Wharf on the Isle of Dogs in London, England. The station forms an artificial island in the West India Docks (North Dock). The five upper levels of the station are a mixed-use development known as Crossrail Place. It will be on the Abbey Wood branch of the Crossrail route between and Custom House. Construction began in May 2009, and it is expected to start receiving passenger rail services in 2021. 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 station will be one of the largest on the Crossrail route when it opens, providing Canary Wharf estate with a connection to the National Rail network and additionally an interchange with Canary Wharf station on the London Underground and Poplar DLR station on the Docklands Light Railway.
Design and construction.
The station is located beneath and within the West India North Dock on an artificial island. The station will extend from east of the Docklands Light Railway bridge to the east end of the dock. It stands within a long concrete box with a long island platform. It is fitted out to with the potential for extension should the need to operate longer trains arise.
Original design.
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 wide shaft to the station depth of below the dock water-level to enable crew and equipment to begin boring the box that would 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.
Redesign and construction.
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.
Throughout 2009 the main focus was on installing 293 interlocking steel piles high and wide into the dock floor using ten-storey high piling cranes and Giken piling machines to form a cofferdam. As part of this, deep reinforced concrete piles were placed through each of the 293 tubes.
On 11 February 2010 Sadiq Khan, then Transport Minister, activated pumps designed to drain nearly 100 million litres () 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 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 Underground 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.
Ownership.
While TfL Rail will operate services and manage the station as a train operating company and will form a part of National Rail, all infrastructure will be owned and maintained by Transport for London and not by Network Rail.
