We’re working on a major four-year package of upgrades to modernise 1980s track and signalling on the lines into London Victoria station.

The upgrades will improve reliability on the network, helping even more passenger and freight trains arrive at their destinations on time.

The installation of the new equipment will see signalling control of the area moving from the Victoria Area Signalling Centre to our new state-of-the-art centre Three Bridges Rail Operating Centre.

The first phase of work, to take place at weekends between London Victoria, Clapham Junction and Balham, and the West London Lines from Clapham to Shepherds Bush, got full underway in 2021 and will continue until after Christmas 2022.

Upgrades between Tulse Hill, Peckham Rye and Crystal Palace, and between Herne Hill, Nunhead, and the Battersea area will follow between 2022 and 2025.

Phase 3 – London Victoria to Clapham and Balham, 2020 to 2022

Work on this phase of the project is now underway and involves:

  • Replacement of all signalling equipment in the Clapham and Balham areas, and lines into London Victoria.
  • Relocation of signalling control for the area from Clapham, to the state-of-the-art Three Bridges Rail Operating Centre (TBROC).
  • Upgrade of track at key junctions surrounding Clapham and Balham with new, more reliable equipment.
  • A new and improved track layout will be installed between Clapham and Victoria stations, improving line speeds and reliability.

Upgrades to track and signalling on other South London lines will follow:

  • Tulse Hill to Peckham Rye and Crystal Palace – 2022 to 2024
  • Battersea (Stewarts Lane) to Herne Hill, Nunhead and Ravensbourne – 2023 to 2025.


Improved reliability and performance of trains in South London and the wider region

  • The new, modern equipment will mean fewer faults and fewer delays for passengers travelling on lines into and out of Victoria.
  • Relocating the signallers for the area to the state-of-the-art Three Bridges Rail Operating Centre will help them work as a team get trains back on time when an incident occurs.
  • The new equipment installed will be easier to maintain, fix and find faults when something does go wrong.
  • New turnback facilities at Clapham and at Balham, will help signallers keep more trains moving during planned engineering work and, when disruption on the railway.

Capacity uplift for the future

  • The improvements will allow an uplift in train services between Clapham Jct and London Victoria in the future.

What is the passenger impact?

Preparation work for the project has been ongoing for several years. The more visible elements of the project which will require access to track are now underway.

Passengers travelling on affected routes are advised to check before travelling at weekends and bank holidays.

On the following dates, no trains will run between Victoria-East Croydon. Most trains will be diverted to London Bridge. Rail tickets will be accepted on London Underground services between London Victoria, London Bridge and Balham, and on London Buses between Balham and Streatham Hill. Tickets will also be valid on South Western Railway services between Clapham Junction and London Waterloo. A limited rail replacement bus service will run between East Croydon and Clapham Junction for local journeys.

2021 passenger impact

  • Saturday 16 to Sunday 17 October
  • Saturday 27 to Sunday 28 November.

Christmas works

  • Saturday 25 December 2021 – Monday 3 January 2022 (10-day closure)
