Sussex Railway Upgrade plan

We’re modernising the railway network to improve passenger journeys across Sussex.

The new concourse at Gatwick Airport station

Between 2024 – 2029  we’re investing £900m as part of our Sussex Railway Upgrades to modernise track, signalling, stations, structures and earthworks.

Key track upgrades will include rebuilding the busy Windmill Bridge Junction at Croydon and the junctions at Redhill.  We’ll replace the 1980s signalling on the Arun Valley Line and between Selhurst and East Croydon with the latest technology.  Work to shore up Victorian era embankments and cutting will take place across the route with key planned interventions to the Haywards Heath cutting and on the West London lines.
