Conwy Valley Line

We are writing to let you know that we will soon be carrying out further essential resilience work on

the Conwy Valley railway line. To carry out this work safely and effectively the line, which runs between Llandudno and Blaenau Ffestiniog, will be closed from 21:30 on Friday 22 November until 10.30 on Sunday 15 December. We would also like to invite you to attend our drop-in events we will be hosting to update you about this work.

As you may know, we experienced severe flooding in the spring which caused significant damage. The railway line was closed so we could carry out extensive repairs to six miles of track, ten level crossings, nine culverts and Dolgarrog station, before reopening in the summer ahead of the Eisteddfod.

Surveys have revealed additional resilience work is required to further reduce the risk of future closures of this vital railway line. During this temporary closure our engineers will work day and night to install over 600 rock bolts in the Ffestiniog Tunnel, replace sleepers along the line and complete essential vegetation management.

We are also continuing to carry out work to replace the flood damaged platform at Dolgarrog station, which will remain closed until this essential platform work is completed. The work at the station will include piling, which involves driving steel piles into the ground using road/rail vehicles with attached hammers. Piling is a noisy activity and we will make every effort to minimise unnecessary noise and complete each pile as quickly as possible. We would like to thank you in advance for your patience during this essential work.
