How much does the train from Belfast to Dublin cost?
Costs vary significantly depending on which direction you’re traveling, when you book, and whether you buy a single or return. The Belfast-to-Dublin route and Dublin-to-Belfast route have different pricing systems because they are managed by two different operators.
Is it cheaper to get the train or drive?
For a single trip, the Enterprise train can be much cheaper than driving once fuel, tolls, and parking in Dublin city center are factored in. A direct comparison shows the savings.
4 cost categories, one pattern: the train wins on single-journey cost but loses on flexibility.
| Factor | Train (Enterprise) | Driving |
|---|---|---|
| Single-journey cost (per person) | From €7.20 (Dublin-originating) or ~€15 (Belfast-originating) (Irish Rail (ROI operator); Seat 61 (travel guide)) | ~€25–€35 (fuel + M1 tolls) |
| Return cost (per person) | From €8 (day return) (Irish Rail (ROI operator)) | ~€50–€70 (fuel + tolls both ways) |
| Additional costs | None (seat included) | Parking in Dublin: €10–€25 per day |
| Travel time | ~2 h 15 min (productive time) | ~2 h 30 min (without traffic) |
The catch: if you’re traveling with two or more people, driving can be cheaper per group. But for solo travelers, the train is the clear financial winner.
What is the cheapest way to travel from Belfast to Dublin?
Advance online booking is the key. Seat 61 (travel guide) notes that Belfast-to-Dublin tickets can be bought for as low as €14.99 each way if booked online in advance on Translink. For trips starting in the Republic, Irish Rail (ROI operator) offers adult single fares as low as €7.20 and day returns from €8.00 for certain station combinations. The cheapest option is always a non-refundable advance single purchased from the correct operator for your departure country.
Irish Rail warns that fares shown on its Dublin–Belfast page apply only to stations originating in the Republic of Ireland. If you’re departing from Northern Ireland, you must book through Translink to get the correct price.
The implication: direction-specific booking is non-negotiable for the best deal.
Is there a fast train from Belfast to Dublin?
The Enterprise is the only direct train service on this cross-border route, but it’s not high-speed rail. Its maximum speed of around 90 mph (145 km/h) is typical for intercity diesel trains.
What is the journey time from Belfast to Dublin by train?
The scheduled journey time is approximately 2 hours 15 minutes, according to Seat 61 (travel guide). Rail Ninja (third-party booking site) lists a slightly shorter time of 2 hours 8 minutes, but official times may vary. There is no high-speed alternative on this corridor.
Are there direct trains?
Yes. The Enterprise is a direct service with no changes required. It runs between Belfast Grand Central and Dublin Connolly. No other direct train operates on this route. If you miss the Enterprise, the only other rail option involves a change at Newry or Dundalk, which adds at least an hour to the journey.
For the business traveler, the Enterprise’s fixed 2-hour-15-minute journey means you can plan meetings on either side of the border without worrying about connections. But it also means you’re stuck with that schedule — no faster alternative exists.
The pattern: journey time is fixed; no premium service exists to shorten it.
Do you need to book a Belfast to Dublin train?
Advance booking is not mandatory, but it is strongly recommended for the best fares. Walk-up tickets are available at station ticket offices, but they cost significantly more.
How do I book Enterprise train tickets?
You can book online through Translink (NI transport authority) when traveling from Belfast, or through Irish Rail (ROI operator) when traveling from Dublin. Both systems include seat reservations with most tickets. Alternatively, you can buy tickets at station ticket offices on the day. Third-party sites like Rail Ninja also sell tickets but may add fees.
Do I need to print my ticket?
Most tickets can be shown on your smartphone. E-tickets are accepted in both Northern Ireland and the Republic. If you buy a paper ticket at the station, keep it with you for inspection on board.
The trade-off: booking early locks you into a specific train but saves money. Flexible walk-up fares cost up to three times more but allow you to take any service.
What station does the Belfast to Dublin train leave from?
The station situation changed in 2024, so it’s worth double-checking before you travel.
Which station in Dublin does the train arrive at?
All Enterprise trains arrive at Dublin Connolly, a major station on the north side of the city center, a short walk from O’Connell Street and the Spire.
What is the difference between Belfast Grand Central and Lanyon Place?
As of October 2024, Enterprise services use Belfast Grand Central Station, which replaced the former Lanyon Place. Seat 61 (travel guide) confirms that the new station opened on 29 October 2024 for Monday–Saturday services. If you’re using an old map or guide, be sure to exit at Grand Central — not the old Lanyon Place stop. The two are adjacent but not identical; Grand Central is larger and better connected to bus services.
The pattern: station changes can confuse first-time travelers. Always use the latest official station names to avoid missing your train.
How often does the train run from Belfast to Dublin?
Frequency depends on the day of the week, with fewer services on Sundays.
7 days, one split: weekdays and Saturdays are the same; Sundays are reduced.
| Day | Number of trains each direction | Approximate frequency |
|---|---|---|
| Monday–Saturday | 8 | Every 2 hours |
| Sunday | 8 (according to Rail Ninja (third-party site)) or 6–7 (official may vary) | Every 2–3 hours |
What are the departure times?
The first train from Belfast Grand Central departs around 06:30, and the last leaves around 19:30. Exact times should be checked on the Translink (NI transport authority) website for the most current schedule. Rail Ninja (third-party site) lists the first Dublin departure at 05:50 and the last at 20:50.
How often does the train run on weekends?
Saturday service matches the Monday–Friday frequency. Sunday has fewer trains, so advance planning is essential if you’re traveling on a Sunday.
The implication: if you miss the last train, your only option is the late bus or an expensive taxi. Check the final departure time carefully for your travel day.
Upsides

- Affordable advance fares
- Comfortable with toilets and luggage space
- Central stations at both ends
Downsides
- Not high-speed; journey over 2 hours
- Limited frequency (every 2 hours)
- Late-afternoon gaps on Sundays

For families or groups, the math shifts — a car may still be cheaper — but the train wins on convenience and productivity. Either way, knowing the station change and booking early is the single biggest factor in a smooth journey.
The Enterprise service from Belfast to Dublin departs from Belfast Grand Central Station, the city’s modern rail hub that replaced the old Lanyon Place station in late 2024.
