Portsmouth bridge improvements

Between Saturday 15 and Sunday 23 January 2022 we will be returning to Portsmouth to continue our work improving the railway. 

Landport viaduct maintenance

In January 2021 we carried out essential maintenance in Portsmouth to improve the reliability of the railway. Works included:

  • Replacing Cow Lane bridge in Cosham
  • Strengthening 10 of the 17 spans of Landport Viaduct at Portsmouth & Southsea station
  • Renewing track and switches and crossings

Our work in January 2022 will finish strengthening Landport Viaduct, allowing trains to continue running at full line speed and keeping them on time.
