Information for Business Stakeholders

Our stakeholder engagement team are dedicated to connecting with and working with businesses impacted by the planned work on the Brighton Main Line. After consulting with stakeholders and listening to your needs, our team has developed a series of resources which will explain the engineering works and reasons for the £300 million investment along the Brighton Main Line.  These resources will help your colleagues, employees and customers prepare for the closures and with minimal impact to their business.  The south coast is a key destination for tourists and home to many commuters.  The planned improvements will help to reduce delays on the line and make future journeys much more reliable. Passengers will benefit from:

  • Improved performance and greater reliability on the line
  • Fewer delays for Southern, Thameslink and Gatwick Express passengers

We will be:

  • Stemming leaks into the tunnels and improving drainage
  • Upgrading or replacing the third rail power system and signalling
  • Replacing track and sets of points, which enable trains to switch between tracks
  • Replacing fencing and improving security to deter trespassers

Proactive engagement is a central tenet of our programme communications strategy.  In addition to our passenger communications, our approach includes bespoke toolkit for businesses, stakeholder forums, face-to-face meetings along with questionnaires and surveys. In order to ensure we really understand the views of our business stakeholders, we are available to answer any queries you may have or meet with you to understand how we can work together.


There are five core guiding principles which we adhere to to ensure we engage with you, our stakeholders, in the most effective way:

Business Toolkit

We have developed a toolkit which is for use by businesses to help you engage with your employees and customers to ensure they are kept updated with information about the Brighton Main Line Improvement Project. As the project progresses, updated tools will become available.


Prepare your business for line closures for preparatory weekend works from September 2018 and for a 9-day closure in February 2019 From September 2018 to May 2019, there will be 15 weekends of preparatory work as well as one 9-day closure from 16-24 February 2019.  Throughout these weekends and this 9-day period, no trains will run between Three Bridges and Brighton or between Three Bridges and Lewes. The unprecedented access provided by these planned closures will allow Network Rail engineers to renew and upgrade a stretch of railway that is responsible for more delays than any other section in the south east of England. The improvement work will focus on four Victorian-era tunnels – Balcombe, Clayton, Patcham and Haywards Heath – and the railway which runs through them.  


Alternative travel and ticketing arrangements  Network Rail and Govia Thameslink Rail (Southern, Thameslink, Gatwick Express & Great Northern) are working closely together to plan the alternative travel advice and ticketing arrangements that will be available during these line closures. Please plan your journey in advance using the National Rail Enquiries Journey Planner.  


Encourage your staff and visitors to work out their plan B The February closure has been carefully planned for school half-term, when passenger numbers are lower and some people may be able to be more flexible with their travel plans or take holiday. Alternative options including replacement buses are still being finalised. Our travel microsite provides information on affected stations.
