The Thameslink Programme

Rebuilding London Bridge station

London Bridge is the fourth busiest station in the country, handling around 54 million passengers each year.

As part of the Government-sponsored Thameslink Programme, London Bridge station is being rebuilt to provide dedicated platforms for up to 18 Thameslink trains an hour in each direction. There’ll be more space, with a concourse the size of the pitch at Wembley Stadium, and improved connections to more destinations.

The station is being rebuilt in phases with construction work at London Bridge station going well and on schedule. The new track and signalling being installed will mean fewer trains delayed outside the station, waiting for platforms to clear.

Both London Bridge rail and Underground stations are open throughout, but Thameslink, Southern and Southeastern and London Overground customers have been and will continue to be, affected at certain times by substantial service changes until the project is completed in 2018.

Work on the ‘through’ platforms and the creation of the new dedicated platforms and tracks for Charing Cross services continues. In addition, work on the dedicated Thameslink platforms is due to be completed and ready for passenger service in early 2018.

Plus, as part of the Programme, by 2018 115 new Class 700 trains will have been introduced on the Thameslink and Great Northern routes. These will offer more capacity, better connections, additional destinations and improved customer information, both on the train and at stations.

What are the main changes to services?

Until the work is finished in 2018, Thameslink cross-London Bedford to Brighton Thameslink trains will not use London Bridge station. Instead they will take an alternative route between East Croydon and London Blackfriars.

There is a reduced off-peak service between Brighton and London Bridge, with only a very limited service between these stations at peak times.

Full details of major changes and travel alternatives


Additional facilities have been created across the network for the new trains, and depots have been redeveloped so that 700s can use them.

Hornsey depot

This historic depot has experienced a new lease of life with the opening of the dedicated Class 700 maintenance facility. The new depot represents millions of pounds of investment by the Department for Transport (DfT) to support the Thameslink Programme.

The site – the size of 12 football pitches – will maintain a total of six classes of trains.

Hornsey is also set to become a centre of engineering excellence, with GTR and Siemens sponsoring 20 engineering apprentices each year to train there.

Horsham depot

The first Class 700 used the depot on 5 December 2016, with full passenger service use planned for early 2017.

Peterborough Spital

This is a brand new, state-of-the-art train servicing facility, with capacity for five x 12 car Class 700 units and purpose-built staff accommodation. It was built by Carillion on behalf of the DfT as part of the Thameslink Programme.


London Bridge

The Bermondsey Dive Under – a major new junction on the approaches to London Bridge –– was commissioned in the new year. This will cut delays and allow more trains to run.

Service disruptions

There will be more closures and changes to services over weekends and bank holidays in 2017 as the rebuild of London Bridge station continues.

There will be substantial changes to services during the following periods:

  • Easter, May/Spring bank holidays
  • 26 August - 2 September 2017
  • 23 December 2017 - 2 January 2018

Passengers are likely to need to change their routes. Check before you travel.

Meldreth, Shepreth and Foxton

Work is due to start on extending platforms at Meldreth, Shepreth and Foxton. This will allow Class 700s to use the stations, ready for when the new fleet goes into operation on the Great Northern route in 2017.
