Overview
The Dublin‑Sligo InterCity line is one of Ireland’s most travelled north‑west corridors. Operated by Iarnród Éireann, the service runs ten times a day from Dublin Connolly to Sligo, covering the distance in just under three hours. The route threads through the Irish midlands, stopping at key towns such as Mullingar, Longford, Carrick‑on‑Shannon and Ballymote before reaching the greystone Sligo station. Passengers enjoy modern blue‑and‑cream coaches with comfortable seating, on‑board Wi‑Fi and a limited trolley service for snacks and drinks.
History
The line was laid in stages between 1846 and the early 1860s, making it one of the longest surviving routes in the Republic. Dublin’s original terminus opened in November 1844 as “Plain Old Dublin Station” and was later renamed Amiens Street before becoming Connolly in 1966, honouring the revolutionary James Connolly. Many of the intermediate stations retain historic names linked to the 1916 Easter Rising – for example, Sligo’s station is now called MacDiarmada after local hero Sean Mac Diarmada. In the 1920s the line was part of the Midland Great Western Railway, later merged into the Great Southern Railway under the 1924 Railways Act. Although the network once spanned over 3,000 miles, today the Dublin‑Sligo line remains the sole rail link serving the northwest.
Recent upgrades and future plans
Between 2023 and 2025 a €29.5 million programme, co‑funded by the EU and the Irish Exchequer, replaced 15.5 miles of jointed rail and wooden sleepers between Longford and Mullingar with continuous welded rail and concrete sleepers. The work, completed in mid‑July 2025, reduced track‑noise and promised a smoother ride. Further upgrades are scheduled for the Mullingar‑Dublin stretch and the Sligo‑Boyle section, with the long‑term goal of cutting the Dublin‑Sligo journey time to under 2 h 45 min.
The line carries roughly half a million passengers each year – a 33 % increase since 1990 – making it a vital transport artery for commuters, tourists and freight alike. During peak periods, especially bank‑holiday weekends, the service can become crowded; Irish Rail has been urged to add extra carriages and consider later evening departures.
What to See & Do
Travelers can turn the journey itself into a mini‑tour. Highlights include:
- River Shannon at Carrick‑on‑Shannon – the train crosses the iconic river, offering a brief glimpse of the waterway that defines much of Ireland’s western landscape.
- Croke Park View – as the train leaves Dublin’s suburbs, the imposing GAA stadium looms on the left, a reminder of Ireland’s sporting heritage.
- Mullingar & Lough Owel – the town is linked to the legend of the Children of Lir; the nearby lakes are renowned for trout fishing.
- Longford’s Viking Roots – the station sits in a town whose name derives from the Norse words for “ship” and “ford”.
- Ballymote’s Historical Monuments – a stop for fans of the Irish diaspora, the town hosts a monument to Brigadier General Michael Corcoran and a tribute to Brother Walfrid, founder of Celtic FC.
- Sligo’s Yeats Landscape – the final stop places you at the gateway to Benbulben, Lough Gill and the Lake Isle of Innisfree, perfect for poetry‑loving wanderers.
While the train does not provide a full dining service, the on‑board trolley sells coffee, sandwiches and sweets at premium prices – consider packing a picnic to enjoy at one of the scenic stations.
Station highlights
- Dublin Connolly – a major hub with Luas Red Line connections, ticket vending machines and lifts.
- Dromod (Co Leitrim) – opened 3 December 1862, the stone‑dressed Victorian building was designed by George Wilkinson. It remains a modest yet charming stop on the line.
- Sligo (Mac Diarmada) station – a terminal with two platforms, an intermediate carriage siding and a passing loop. The elevated building dominates the streetscape and offers lifts and tactile paving for accessibility. The adjacent Bus Éireann depot provides onward travel to Drumcliffe, the town centre and the wider northwest.
