Severn Tunnel rail line renewal
In a UK rail industry first, the South Rail Systems Alliance (SRSA), comprised of Colas Rail UK, Network Rail & Aecom, renewed the entirety of the down line of the Severn Tunnel in a 16-day blockade.
Between 3rd and 19th July 2024 SRSA installed more than 7,097 metres of new track on the down line, starting at the England entrance and moving through to Wales.
With a phased renewal programme, the team completed the renewals in approximately 700 metre sections so that a conveyor belt of activities could progress seamlessly through the tunnel using multiple engineering trains and work fronts. In total the team handled:
• 7,097 metres of new track system installed
• 66 x 216 metre rails
• 10,800 sleepers
• 22,000 tonnes of new ballast
• 24,000 tonnes of spoil.
