Brighton Main Line improvement project

Network Rail will carry out major engineering works between Three Bridges and Brighton / Lewes / Hove, closing the line for 9 days from Saturday 19 to Sunday 27 February 2022, to deliver track replacement work and build a new underpass. Supporting work will also take place at weekends before and after the main closures.

What area is impacted?

The map below shows the general service arrangements.


This will mean changes to train services across the Southern and Thameslink networks and significantly longer journey times for some passengers.

No trains will serve the following stations:

  • Balcombe
  • Haywards Heath
  • Wivelsfield
  • Burgess Hill
  • Hassocks
  • Preston Park
  • Plumpton
  • Cooksbridge

Replacement buses will run between Three Bridges and Brighton / Lewes.

What dates are affected?

  • Saturday 15 – Sunday 16 January 2022
  • Saturday 12 – Sunday 13 February 2022
  • Saturday 19 – Sunday 27 February 2022 (main 9-day blockade)
  • Saturday 5 – Sunday 6 March 2022
  • Sunday 3 April 2022

Please note services on the Brighton Main Line may be affected outside of these dates for other engineering work. Please check before you travel.

What does this mean for my journey?

We are currently developing our plans for the alternatives and will share more information closer to the time.

Why is this happening?

The nine-day closure in February is so that Network Rail can renew a junction near Haywards Heath, carry out track replacement in the Burgess Hill area and upgrade some drainage systems near Balcombe, all work that can only be done when trains are not running. These improvements will help to avoid future disruption to your journeys in the area.

Engineers will also use the time to construct a new pedestrian underpass underneath the railway near Hassocks.

Doing this work together during an extended closure over nine days avoids the need for a lot of separate weekend closures.
