Essential works on Derry to Coleraine line planned this weekend

Partial line closures are planned on the Derry line on Saturday, September 20, Sunday, September 21 and Monday, September 22 2025 between Derry and Coleraine.

Services will have rail replacement buses in operation.

Translink is advising passengers to plan ahead as a series of essential planned engineering works will affect services between Derry and Coleraine.

To make the most of this closure period and reduce repeated disruption, Translink teams will carry out a range of essential works at multiple locations, including culvert repairs, Castlerock and Downhill tunnel maintenance, third-party infrastructure works, survey activities, and general maintenance and safety inspections. This coordinated approach helps maintain the safety and reliability of the rail network.

During these periods, rail replacement bus services will be in operation to minimise disruption. Valid rail tickets will also be valid on appropriate scheduled bus services.

Rail services between Coleraine and Belfast Grand Central Station will run as timetabled and Bangor, Larne, Portadown, and Cross Border services – are unaffected.

There will also be some changes to early trains on Tuesday, September 23.

John Glass, Director, Infrastructure and Projects at Translink, said: “We’ve planned these works carefully so that several essential upgrades – from tunnel repairs and drainage improvements to surveys and routine maintenance – can be delivered in one closure period.

We know the closure will affect journeys, particularly on the Monday, so we’re asking everyone to plan ahead, check timetables, and allow extra travel time.

We’d like to thank all our passengers and local neighbours for their patience and understanding while these important works are carried out, helping to maintain safe and reliable services for the future.”

Passengers travelling from Derry to Belfast for the Belfast City Half Marathon on Sunday, September 21, are advised to take the 06:00 212 Service from Foyle Street Station, arriving at Belfast Grand Central Station at 08:00. From there, scheduled services are available to Lanyon Place.
