Key takeaway
Complete guide to Irish Rail intercity trains in Ireland, covering routes, ticket prices, booking discounts, and how they compare to buses in 2025.
Irish Rail (Iarnród Éireann) operates the national rail network, connecting Dublin to all major cities. Trains are faster and more comfortable than buses on most routes, though typically pricier — here's what you need to know.
What Are the Main Irish Rail Intercity Routes?
Key intercity lines radiate from Dublin: Dublin–Cork (via Mallow), Dublin–Galway, Dublin–Limerick, Dublin–Waterford, Dublin–Sligo, Dublin–Belfast (the Enterprise service, jointly operated with Translink), and Dublin–Westport/Ballina. Dublin has two main intercity stations: Heuston (serving the south and west, including Cork, Galway, Limerick) and Connolly (serving the north, east, and Belfast).
How Long Do Journeys Take?
Dublin to Cork: approximately 2.5 hours. Dublin to Galway: around 2 hours 10 minutes. Dublin to Belfast (Enterprise): about 2 hours. Dublin to Limerick: roughly 2 hours 15 minutes. These are among the fastest ways to travel between Ireland's major cities without driving.
How Much Do Train Tickets Cost?
Fares vary significantly by how far in advance you book — advance 'Saver' fares on routes like Dublin–Cork can start around €15–€25 one-way, while walk-up 'Open Return' fares can exceed €70–€100. Booking via irishrail.ie as early as possible (tickets typically release around 3 months ahead) secures the cheapest prices, much like air travel pricing.
What Discounts Are Available?
Students with a valid Student Leap Card get roughly 40% off standard adult fares. Young Adult cardholders (ages 19–23) also get discounted travel. Children under 5 travel free, and ages 5–15 pay child fares (roughly half the adult rate). The Irish Rail website and app show all available fare classes at booking.
Trains vs Buses: Which Should You Choose?
Choose trains for speed and comfort, especially on longer routes like Dublin–Cork or Dublin–Galway, where you save 30–60 minutes versus the bus and get more space to work or relax. Choose buses for budget travel, more frequent departures on some routes, or destinations without a direct rail line — many smaller towns are bus-only.
