This work is the second phase of a major upgrade delivered this year and includes the installation of 600 rock bolts in the Ffestiniog Tunnel, the replacement of sleepers along the line and vegetation management. Work will also continue to replace the flood damaged platform at Dolgarrog station, which remains closed.

The line was initially closed in March, following extreme weather that washed out ballast and damaged infrastructure over a six-mile stretch. Work during this phase included the removal of 8,000 tonnes of wash out materials, the installation of additional culverts and over 7,500 tonnes of 'rock armour' to improve flood resilience.
