Elizabeth line

In 2005, ahead of Crossrail's hybrid bill submission, a number of feeder routes were considered by CLRL west of Paddington and east of Liverpool Street. It was viewed, given the 24 trains-per-hour (tph) core frequency, that two feeder routes, each of 12tph, could be taken forward.[6]

In the west, a route to Maidenhead (later extended to Reading) and Heathrow Airport was selected. In the east, routes to Abbey Wood (curtailed from Ebbsfleet to avoid conflicts with the North Kent lines) and Shenfield were selected.

The Crossrail Act 2008 authorising the construction project received royal assent on 22 July 2008.[7][8] In December 2008, TfL and the DfT announced that they had signed the "Crossrail Sponsors' Agreement". This committed them to financing the project, then projected to cost £15.9 billion, with further contributions from Network Rail, BAA[9] and the City of London.[10]

Construction of Crossrail at Tottenham Court Road in September 2011

Work began on 15 May 2009 when piling works started at the future Canary Wharf station.[11]

Boring of the railway tunnels was officially completed in June 2015.[12] Installation of the track was completed in September 2017.[13] The ETCS signalling was scheduled to be tested in the Heathrow tunnels over the winter of 2017–2018.[14]

At the end of August 2018, four months before the scheduled opening of the core section of the line, it was announced that completion was delayed and that the line would not open before autumn 2019.[15] After multiple delays, in August 2020 Crossrail announced that the central section would be ready to open "in the first half of 2022".[16]

In May 2021, trial running commenced.[17]

On 17 May 2022, the line was officially opened by the Queen in honour of her Platinum Jubilee. She was not scheduled to attend the event, but decided to attend with her son, Prince Edward, to unveil the plaque commemorating the official opening.[18]

Though the main tunnels under central London had not yet been opened, passenger operations on the outer branches of the future Elizabeth line were transferred to TfL for inclusion in the concession – this took place over several stages beginning May 2015. During this initial phase of operation, services were operated by MTR under the TfL Rail brand. Following the practice adopted during the transfer of former Silverlink services to London Overground in 2007, TfL carried out a deep clean of stations and trains on the future Elizabeth line route, installed new ticket machines and barriers, introduced Oyster card and contactless payment, and ensured all stations were staffed. Existing rolling stock was rebranded with the TfL Rail identity.[19]

Crossrail is the name of the construction project and of the limited company, wholly owned by TfL, that was formed to carry out construction works.[19][34]

The Elizabeth line is the name of the new service that is on signage throughout the stations. It is named in honour of Queen Elizabeth II.[35][36] The Elizabeth line logo features a Transport for London roundel with a purple ring and blue bar with white text. Unlike lines of the London Underground, the roundels contain the word "line".

TfL Rail was an intermediate brand name which was introduced in May 2015 and discontinued in May 2022. It was used by TfL on services between Paddington and Heathrow Terminal 5 and Reading, as well as trains between Liverpool Street and Shenfield.[37]

The new platforms at Farringdon

Ten new stations have been built in the central and south east sections of the line, and thirty-one existing stations were upgraded and refurbished.[40] Nine of the ten new built stations were fully opened on 24 May 2022 with Bond Street as the exception which, as of February 2022, still needed further final finishing prior to testing and commissioning.[41][42] All stations are equipped with CCTV[43] and because of the length of trains, central stations have train indicators above the platform-edge doors.[44] All 41 stations will be step-free, with 13 of these (the central and Heathrow stations) having level access between trains and platforms.[45]

Although the trains are 200 metres (660 feet) long, platforms at the new stations in the central core are built to enable 240-metre-long (790 ft) trains in case of possible future need. In the eastern section, Maryland and Manor Park have not had platform extensions, so trains use selective door opening instead.[46] At Maryland this is because of the prohibitive cost of extensions and the poor business case,[47] and at Manor Park it is due to the presence of a freight loop that would otherwise be cut off.[48]

A mock-up of the new stations was built in Bedfordshire in 2011 to ensure that their architectural integrity would last for a century.[49] It was planned to bring at least one mock-up to London for the public to view the design and give feedback before final construction commenced.[44]

Class 345 trains at the Paddington terminus in 2018

The Elizabeth line route exclusively uses nine-car Class 345 trains for the services on the routes.[50][32] The requirement was for 65 trains, each 200 metres (660 feet) long and carrying up to 1,500 passengers.[50] The trains are accessible, including dedicated areas for wheelchairs, with audio and visual announcements, CCTV and speaker-phones connected to the driver in case of emergency.[51] They will run at up to 140 km/h (90 mph) on certain parts of the route.[52]

In March 2011, Crossrail announced that five bidders had been shortlisted for the contract to build the Class 345 and its associated depot.[53] One of the bidders, Alstom, withdrew from the process in July 2011. In February 2012, Crossrail issued an invitation to negotiate to CAF, Siemens, Hitachi and Bombardier, with tenders expected to be submitted by mid-2012.[54] In 2013, Siemens also withdrew from the bid, but will provide signalling and control systems for Crossrail.[55] In December 2013, the European Investment Bank (EIB) agreed to provide loans to Transport for London for the rolling stock of up to £500M.[56] On 6 February 2014, it was announced that Canada's Bombardier had been awarded a £1bn contract to supply 66 trains,[3][57] with an option for 18 more.[3] Bombardier Transportation would later be acquired by withdrawing bidder Alstom on 29 January 2021.

The first train entered service on 22 June 2017 on the TfL Rail route between London Liverpool Street and Shenfield as a seven-carriage unit,[58] since, before the platforms were lengthened,[59] the complete nine-car sets could not be accommodated at Liverpool Street station.[60]

In July 2017 an option for five more units was exercised taking the order to 70 units.[61]

Eight Class 315 trains, which were built in 1980–1981, are still needed to run on the Liverpool Street-Shenfield via Stratford section of the Elizabeth line. They will cover Elizabeth line services during weekday peak hours for an initial few months until there are enough Class 345 trains to run the service, as some are out of service temporarily whilst extra carriages are added to them.[62]

The Elizabeth line uses 25 kV, 50 Hz AC overhead lines, already in use on the Great Eastern and Great Western Main Lines.

The Heathrow branch started using the European Train Control System (ETCS) in 2020. The Automatic Warning (AWS) and Train Protection & Warning (TPWS) systems are used on the Great Western and Great Eastern Main Lines, with possible later upgrades to ETCS. Communications-based train control (CBTC) is installed in the central section and the Abbey Wood branch.[64][65][66]

The Elizabeth line has depots in west London at Old Oak Common TMD, in south-east London at Plumstead Depot, and in east London at Ilford EMU Depot.[67][68]

The Elizabeth line (in purple) in relation to other commuter railway lines in central London

Upon opening, the line ran as three physically separate services: between Reading or Heathrow airport and London Paddington in the west; from Paddington via Liverpool Street to Abbey Wood in the centre; and between London Liverpool Street and Shenfield in the east. To connect between services, a walk between the separate stations at Paddington or Liverpool Street was required.

As of 6 November 2022, when through-running began, there are two main service groups, overlapping through the core section: from Reading or Heathrow Airport to Abbey Wood; and from Paddington to Shenfield. The off-peak weekday service is as follows:[69]

Some early morning and late night services run into London Paddington main line terminus instead of going across central London. Likewise, some early, peak-direction, and late trains run between London Liverpool Street main line terminus and Gidea Park, bypassing Whitechapel.

In May 2023, it is planned to allow trains to run from both eastern branches to west of Paddington. This will allow both more flexible, and higher frequency, services.

Before the COVID-19 pandemic, the Elizabeth line was predicted to carry over 200 million passengers annually immediately after opening;[73] this was expected to relieve pressure on London Underground's lines, especially the Central line.[74] Farringdon is expected to become one of the busiest stations in the UK, due to it being the key interchange station with Thameslink services.[75] In a business plan for the line published in January 2020, Transport for London predicted total annual revenues from the line of nearly £500 million per year in 2022/23 (its first full year of operation) and over £1 billion per year in 2024/25.[73] By the time the line opened, TfL had reduced their passenger forecasts because passenger travelling habits changed during the pandemic; the estimate was between 130 and 170 million passengers by 2026.[76]
