  • Services that include stops at intermediate stations add roughly 10–15 minutes to the total trip time.

Which Dublin train station goes to Limerick?

Dublin Heuston as the primary station

  • Most services from Limerick arrive at Dublin Heuston, the main station for trains from the south and west, confirm Irish Rail.
  • Heuston is directly linked to Dublin city centre by Luas Red Line, bus, and taxi.

How to reach Connolly station from Limerick

  • To get from Limerick to Dublin Connolly, you typically need to change trains at Heuston and take a Luas or taxi across the city — there is no direct service, per Irish Rail.
  • Alternatively, some routes involve changing at Limerick Junction, adding 30–45 minutes to the total journey.

The catch: travellers booked to Connolly should plan for a connecting trip across Dublin; it is not a single-station route.

How much is a train ticket from Limerick to Dublin?

Adult single fares

The official fare table for the Dublin-Limerick-Ennis route shows adult single fares ranging from €4.80 to €13.55, depending on the zone and type of ticket, according to Irish Rail’s official fare table.

Day return and monthly tickets

  • An adult day return costs €8.85 on the same route, per Irish Rail.
  • Monthly season tickets vary; for a child the cost ranges from €38 to €57, per the same source.
  • Advance single fares start at €23, as listed on Irish Rail’s web fares page.

Child fares

  • Children under 5 travel free in standard class with a passenger holding a valid ticket, subject to seat availability, states Irish Rail’s tickets-explained page.
  • A child low fare on the route is €10.39, according to Irish Rail Web Fares.

Why this matters: the difference between an advance web fare and a walk-up single can be €5–€10 — enough to change the decision for a family.

Is it cheaper to buy train tickets on the day or before?

Advance purchase discounts

  • Irish Rail explicitly states that booking online in advance is the way to access its lowest fares, per its official timetable page.
  • Web fares for the Limerick–Dublin route start at €14.99 for adults and €10.39 for children, according to Irish Rail’s web fares page.

On-the-day fares compared to advance

  • On-the-day singles cost between €4.80 and €13.55, but these are generally priced higher than the advance web fare, per Irish Rail.
  • Booking at the station counter or ticket machine does not offer the same discounts.
Why this matters

For a single traveller, booking online at least a few days ahead saves roughly €8–€12 compared with buying on the day. For a family of four, that saving jumps to €30–€40.

The trade-off: flexibility costs money. If your plans are firm, book ahead; if they are fluid, accept a higher walk-up price.

Are trains running from Limerick to Dublin?
