In January we carried out essential maintenance and made improvements in Portsmouth to improve the reliability of the railway.

Landport viaduct maintenance

Working around the clock over a number of days in January, engineers completed the following:

  • Replaced Cow Lane bridge in Cosham
  • Strengthened ten of the 17 spans of the Landport Viaduct, the structure that supports the two platforms for trains to Portsmouth Harbour
  • Renewed and refurbished several sets of switches and crossings, including the heating component that keeps trains moving in freezing temperatures
  • Renewed timber rail supports at Portsbridge Creek near Hilsea and St George’s bridge on the approach to Portsmouth Harbour.
  • Installed new sidings at Fratton train care depot as part of a long-term programme of improvements to the facility used by Great Western Railway (GWR) and South Western Railway (SWR).

Work to paint Landport Viaduct is now underway and will continue until April 2021.

Future work

Landport Viaduct’s remaining seven spans will be strengthened at a later date in 2022 and will also require a line closure between Fratton/Portsmouth & Southsea and Portsmouth Harbour.

Details of future work will be published on this page.
