Specialist divers are pouring underwater concrete to protect two major railway viaducts carrying the West Coast main line in Carlisle.

Detailed laser surveys carried out by Network Rail showed fast flowing water on the River Eden has caused parts of the riverbed to wash away posing a risk to the viaduct foundations.

Because of the deteriorating riverbed condition, trains have been running at reduced speeds of 20mph over the Victorian and 1940s-built structures.

Approximately 900 tonnes of special setting concrete is now being poured by the diving teams to provide a stable platform for the viaducts’ columns or piers.

The immediate repairs are being made to the structures as part of a £1.3m Great North Rail Project investment.
