Working on Chalkwell Station

Major rail upgrades underway in South Wales

Network Rail (Wales and Borders) has started a comprehensive programme of engineering works across key rail corridors in South Wales as part of its ongoing commitment to maintaining and improving rail infrastructure.

The works, taking place between Saturday 2 August and Monday 11 August, involve track renewals, drainage improvements, and essential maintenance to keep a safe and reliable railway for passengers and freight operators alike.

Areas affected are:

  • Dynevor Junction to Morlais Junction
  • Jersey Marine to Hendy
  • Llangyfelach Tunnel and surrounding track sections
  • Penllergaer Tunnel to Grovesend

Key engineering activities include:

  • Track renewals through Llangyfelach Tunnel, and various sections between Dynevor Junction and Felin Fran Junction.
  • Track and drainage upgrades and renewals between Grovesend and Penllergaer

The works will improve track reliability and see smoother journeys for passengers, while reducing the risk of service delays and the potential for anything going wrong with the infrastructure. They will also increase resilience against extreme weather.
