Reopen key rail links, add airport access, and connect communities with frequent, greener travel.
The Belfast Circle Line Campaign is a grassroots initiative advocating for better rail connectivity across Greater Belfast. The vision centers on reopening the Knockmore Line (Antrim-Lisburn) as the foundation for a true orbital service.
This would transform how people move around the region - reducing dependence on cars, cutting journey times, and opening up access to jobs, education, and leisure without forcing every trip through the city center.
We're calling for improved service frequency, new and upgraded stations serving Belfast International Airport, Belfast City Airport, and growing rural villages and commuter towns.
This is a campaign vision - detailed engineering, approvals, and delivery would be led by the relevant authorities. We're here to build public and political support for making it happen.
A comprehensive rail network connecting communities, airports, and employment hubs
Reopen the Knockmore Line (Antrim–Lisburn) and upgrade existing corridors for modern, frequent service.
New and upgraded stations at Belfast International Airport, City Airport, and key growth areas.
Seamless connections with buses, walking, and cycling infrastructure for end-to-end journeys.
Rail access to Belfast International Airport and improved services to City Airport - no more expensive taxis or limited bus routes.
Orbital journeys without routing through the city centre - cutting journey times by up to 40 minutes for some trips.
Better connections to employment hubs, universities, and training centers - opening opportunities for communities currently underserved.
Shift thousands of car journeys to rail - reducing carbon emissions, improving air quality, and easing pressure on M1, M2, and city centre roads.
Enhanced rail connectivity makes Belfast more accessible to visitors, boosting local hospitality, tourism attractions, and nightlife.
Better connectivity drives economic development, creating jobs and investment opportunities across the region.
