Map of proposed changes at Bank and Monument Map of proposed changes at Bank and Monument

Bank and Monument together are used by more than 52 million passengers a year. Demand has risen by around a quarter since 2008.

Improving the station is critical to keep London working and growing and is a key part of our plans to increase frequency on the Northern line.

Our plans

By 2022, the interlinked stations will feature several new escalators, a new station entrance and more room for Northern line passengers. This will increase capacity at the station by 40%.

The modernisation will include:

  • A new railway tunnel and platform for the Northern line that will reduce interchange times and create more space for passengers
  • Step-free access to the Northern line and DLR platforms
  • More direct routes within the station, with two new moving walkways
  • Two new lifts and 12 new escalators
  • A new station entrance in Cannon Street

Walbrook entrance - opened November 2018

A new station entrance on Walbrook (at the Bloomberg building) now offers easier access to the Waterloo & City line. The entrance has two lifts, four escalators and a new ticket hall.


More than 200 engineers and staff will work on site at Bank 24 hours a day until 2021. The station will remain open to customers throughout the work. Most of the construction work will take place below ground to minimise construction impact on the historically significant site which is bordered by 31 listed buildings.

Two main worksites are needed to construct the scheme:

  • The area bounded by Cannon Street, Abchurch Lane, King William Street and Nicholas Lane is known as the 'Whole Block' worksite. The new station entrance on Cannon Street, lifts and escalators will be built from this site
  • Most of the tunnelling works will take place from the Arthur Street worksite. This means Arthur Street is closed to vehicles - however, pedestrians, dismounted cyclists and deliveries still have access

We aim to keep disruption to a minimum during construction and manage environmental impacts with industry best practices.

Key progress milestones

  • Removed all six buildings to ground floor level on the Whole Block site
  • Excavated the main access shaft for the Arthur Street tunnelling works
  • Installed two silos to support tunnelling works
  • Started tunnelling work at Arthur Street to construct the new southbound Northern line railway tunnel

Transport and Works Act Order

We were granted a Transport and Works Act Order (TWAO) by the Secretary of State for Transport that came into force in January 2016. The TWAO authorises us to construct the works and operate the new section of railway.

Our TWAO application documents, Statement of case, factsheets and settlement deed procedure are on the Bank station capacity upgrade page.

Northern line City branch in 2020

We will need to close part of the Northern line City branch in 2020 to connect new and existing sections of tunnel safely. Closures will be as shown below, with reduced frequencies on those sections of the City branch which remain open.

  • April-May 2020 (40 days): line closed in both directions Moorgate to Kennington
  • May-August 2020 (77 days):
    northbound - trains not stopping at Bank
    southbound - line closed Moorgate to Kennington

Alternative services

There will be room for displaced passengers on the District/Circle lines and Elizabeth line (currently being built by Crossrail Ltd), which will be fully operational by 2019. In addition, Thameslink frequency will be up to 24 trains per hour between Elephant & Castle/London Bridge, Blackfriars, City Thameslink and King's Cross.

To further help passengers, we will:

  • Run 33% more trains on the Northern line Charing Cross branch
  • Review bus use and consider enhancing services where necessary
  • Investigate scope for passengers to use alternative National Rail services, such as Waterloo to London Bridge, and London Bridge to Cannon Street
  • Review available walking space on the Moorgate to London Bridge pedestrian corridor

  • 15 December 2015: TWAO decision
  • April 2016: works start
  • Spring 2017: tunnelling starts
  • April-August 2020: Northern line closure
  • Late 2022: works completed


Between them, Bank and Monument stations are served by five Underground lines as well as the DLR.

Currently, 123,000 passengers use Bank station during the morning peak period, about 51,000 of whom are changing between lines.

The two stations consist of three ticket halls, six lifts, 10 platforms, 15 escalators and two 300-foot moving walkways, making one of the largest and most complicated subterranean railway complexes in the world.

Our proposals follow public consultations held in 2011, 2012, 2013 and 2014.
