Translink Advances Belfast Track Renewal as All-Island Rail Review Plots New Lines to Airport and Derry
Translink is pressing ahead with a major programme of infrastructure investment in Northern Ireland's rail network, with the Central Area Track Renewal project modernising the heart of the Belfast system while the All-Island Strategic Rail Review has completed feasibility studies for transformative new routes that could reshape connectivity across the island — including a long-awaited rail link to Belfast International Airport.
Background
Northern Ireland's rail network has long been regarded as one of the most underdeveloped in these islands. The legacy of decades of underinvestment — compounded by the disruption of the Troubles, which made infrastructure development both difficult and politically contentious — left the province with a network that, while reliable on its core routes, lacks the reach and capacity of comparable systems in Britain and the Republic of Ireland.
The Belfast to Dublin Enterprise service, operated jointly by Translink and Iarnród Éireann, is the flagship cross-border route, but the journey time of approximately two hours and ten minutes between the two capitals compares unfavourably with high-speed rail connections between comparable European cities. The rolling stock on the route is ageing, and the infrastructure — particularly on the Northern Ireland section — requires significant investment to support faster and more frequent services.
The All-Island Strategic Rail Review, commissioned jointly by the Irish and British governments and published in 2023, set out an ambitious long-term vision for rail development across the island. The review identified a series of priority projects that could transform connectivity, reduce journey times, and shift passengers from road to rail — a critical objective given the climate commitments of both governments. The feasibility studies completed in 2025 and 2026 have moved several of these projects from aspiration to concrete planning.
Key Developments
The Central Area Track Renewal project in Belfast is the most immediately visible element of Translink's current investment programme. The project is modernising tracks and signalling between Lanyon Place — Belfast's main railway station — and Yorkgate station to the north of the city centre. The work is being carried out primarily during nights and weekends to minimise disruption to passengers, with bus substitutions provided on affected services during engineering possessions.
The renewal is a necessary precondition for any future increase in service frequency on the Belfast network. The existing infrastructure, much of which dates from the mid-twentieth century, is approaching the end of its operational life, and the signalling systems in particular need to be upgraded to support the kind of high-frequency, high-reliability operation that modern passengers expect.
On the strategic planning front, the All-Island Rail Review feasibility studies have confirmed the viability of several major projects. The reopening of the Antrim-Lisburn line, with a new station and rail link to Belfast International Airport, has been identified as a high-priority project that would address one of the most glaring gaps in Northern Ireland's transport network. The airport currently has no rail connection, forcing passengers to rely on bus services or private cars — a situation that compares poorly with Dublin Airport, which will be served by the MetroLink project currently in development.
The restoration of the Portadown-Derry/Londonderry line via Dungannon and Omagh has also been confirmed as feasible. This route, which was closed in 1965, would reconnect the west of Northern Ireland to the rail network for the first time in six decades, providing a vital transport link for communities in Tyrone and Fermanagh that currently have no rail access. The restoration of the Portadown-Armagh line is a further project under active consideration.
On the cross-border Enterprise service, a new fleet of eight tri-mode trains — capable of operating on electric, diesel, and battery power — is in development. These trains are scheduled to enter passenger service in 2030 and are designed to reduce the Belfast-Dublin journey time to under two hours, making the service significantly more competitive with road and air travel.
Why It Matters
The investment in Northern Ireland's rail network matters for reasons that go well beyond transport convenience. Rail connectivity is a fundamental driver of economic development, and the communities that lack it — particularly in the west of Northern Ireland — are at a structural disadvantage in attracting investment and retaining population. The restoration of the Portadown-Derry line would be transformative for towns like Dungannon and Omagh, which have been effectively cut off from the rail network for two generations.
The airport rail link is equally significant. Belfast International Airport handles millions of passengers annually, and the absence of a rail connection is a genuine competitive disadvantage for the region. The comparison with Dublin, where MetroLink will provide a direct rail link to the airport, is one that business leaders and politicians in Northern Ireland have been making with increasing urgency.
The all-island dimension of the rail review is also politically significant. Cross-border infrastructure investment is one of the areas where practical cooperation between the two jurisdictions has been most productive, and the joint commissioning of the review reflects a shared recognition that the island's transport network needs to be planned and developed as a whole rather than as two separate systems.
Local Impact
For commuters in Belfast, the Central Area Track Renewal will bring short-term disruption but long-term benefits in the form of more reliable and potentially more frequent services. Passengers on the Yorkgate line — which serves the north of the city and connects to Antrim and Derry — will notice the improvement most directly. Translink has been communicating the works programme to passengers through its app and website, and the bus substitution arrangements have been designed to minimise the impact on journey times.
For communities in Tyrone and Fermanagh, the prospect of rail restoration is a matter of profound significance. These are areas that have seen significant population decline and economic marginalisation, and the restoration of rail connectivity would be a powerful signal of investment in their future. The feasibility studies are an important step, but the political and financial commitment to actually build the lines will be the critical test.
What's Next
The Central Area Track Renewal is expected to continue through 2026 and into 2027, with the full programme of works scheduled for completion before the end of next year. The All-Island Rail Review projects will move into detailed design and planning phases over the coming years, with the airport rail link expected to be the first major new project to progress to planning application stage. The new Enterprise trains are on track for delivery in 2030, subject to the manufacturing programme proceeding as planned.
