Three Bridges to Brighton and Lewes

Three Bridges and Brighton/Lewes 9-day closures – Saturday 19 to Sunday 27 February 2022

The Brighton Main Line between Three Bridges and Brighton/Lewes will close for nine-days from Saturday 19 to Sunday 27 February 2022 as part of major project to deliver long-term reliability improvements for passengers. Supporting work will also take place at weekends before and after the main closures. 

Network Rail engineering work

Network Rail will use the time when lines are closed to replace 1980s track at Copyhold junction (near Haywards Heath), and at Burgess Hill.  A new underpass to provide safe access under the railway at Hassocks will also be built during the nine-day closure.

Additional improvements on the line will be brought into the project over the coming months to ensure as much work as possible is done to give passengers additional benefits and minimise future disruption to passengers and neighbours.

When lines are closed, alternative travel arrangements will be put place for passengers, similar to the February 2019 Three Bridges to Brighton closure, including replacement buses and ticket acceptance on open routes. 

What work is being delivered?

Copyhold Junction and Burgess Hill track renewal

  • Replacing over 7,000 tonnes of ballast – the stones beneath the track that give support
  • Replacing over 1,000 metres of track
  • Renewing eight sets of points – these are the mechanical systems that move the switches and crossings that guide trains from one track to another.

More reliable journeys

  • Renewing the track and equipment at Copyhold Junction, a key junction on the network, will help maintain reliability on the Brighton Main Line.
  • The work will enable  line speed improvements and will support service recovery when delays do occur.

Less disruption to passengers and neighbours

  • Using an extended line closure to do the work will minimise overall disruption to passengers and neighbours. We can deliver the benefits more quickly and cost-effectively through a nine-day closure..
  • The alternative to delivering this investment over an extended closure in winter, when demand is naturally lower, was up to 20 weekend closures or multiple bank holiday closures over two years. 

New pedestrian subway under the railway at Hassocks

Following the closure of Woodside level crossing at Hasssocks due to misuse and safety concerns, a new underpass will be built to provide safe access under the railway. This will mean;

  • Safe access under the railway for local people
  • Fewer delays due to trespass and crossing misuse.

Passenger information

The alternative travel arrangements that will be put in place will be similar to the February 2019 Three Bridges to Brighton closures. We are working closely with Govia Thameslink Railway to plan the alternative travel arrangements and will regularly liaise with stakeholders and passenger groups as the plans develop.

We will also launch a large-scale passenger communications campaign targeting all passengers affected by the line closures. The campaign will ensure passengers and businesses are fully aware of the closures, the impact on journeys, the alternative travel options available and the benefits the work will bring for the region. 

Detailed travel advice for the 9-day closure, including the times of replacement buses and alternative train services via alternative routes will be available on this page and on train operator websites.
