A planned upgrade to the railway line between Derry city and Coleraine has been confirmed in a letter of offer from the Department for Infrastructure.
The civil engineering work involves renewing the entire track between the Co Derry villages of Castlerock and Eglinton and is pencilled in for completion before 2028.
The news has been welcomed by local politicians, who say the rail upgrade will go "a long way to address regional imbalance" in infrastructure.
