Key takeaways
- Ireland runs on a 1,600 mm track gauge - the trains here have no equivalent on Europe's standard-gauge network.
- Connolly is a terminal and through station at the same time: dead-end tracks for long-distance services, through tracks for suburban traffic via the Loop Line.
- The Belfast service is the island's only cross-border line, and the most interesting thing here in terms of rolling stock.
- For photos, head to the quays beneath the elevated viaduct - freely accessible, with the city as a backdrop.
- There's almost no freight traffic. If you're after locomotives and freight trains, Ireland is fundamentally the wrong place.

The best viewpoints
Every viewpoint listed here is on publicly accessible ground. Tracks, shunting areas and operational railway land are off limits – even if the angle would be better from there.
Elevated through platforms
The station sits on a viaduct, and the through tracks lead towards the city centre via the Loop Line. From here you see the suburban services running at a dense frequency, plus the trains carried on over the river. The elevated position gives you a clear view over the rooftops.
Terminal tracks towards the north
The dead-end tracks are used for trains to the north and north-west. Sets stand here longer, so you can read off numbers at your leisure and document trains that don't appear in suburban service.
Riverside quays beneath the Loop Line
The elevated line crosses the city centre on a steel bridge structure. From the public riverside paths you get trains over the water with the city as a backdrop - the only spot in Dublin where the railway and the city really come together.
Forecourt on Amiens Street
In front of the station lie the tram stop and the central coach station. If you document local transport as a whole, you have three systems within a few hundred metres here - plus the historic station facade with its distinctive tower.
Elevated station in the city centre
One stop further on the Loop Line lies a narrow elevated halt between the riverside streets. For suburban trains, this is the better viewpoint than Connolly itself: a tight frequency, head-on arrivals and daylight instead of a canopy.
What you will see here
Your haul at Dublin Connolly
- Irish broad gauge: a 1,600 mm track gauge, a self-contained world of rolling stock with no European equivalent
- DART suburban trains under DC overhead wire at a dense frequency
- Cross-border traffic to Belfast as the island's only international connection
- Diesel multiple units to the north and west, with no overhead wire
- The Loop Line viaduct as both an urban landmark and a photographic subject
- Tram and coach services right on the station forecourt
Is it worth the trip?
In favour
- A track gauge and a fleet of trains you won't see anywhere else in Europe
- Suburban services at a dense frequency keep things moving throughout
- Cross-border traffic with its own rolling stock
- Tram and coach station right on the doorstep
- A central location, everything within walking distance
- Free viewpoints at the quays beneath the elevated line
Against
- Noticeably less traffic than at comparable stations on the continent
- Very little freight traffic - Ireland has hardly any rail freight left
- The fleet is limited, with variety coming mainly from liveries
- The canopy over the terminal tracks costs you light
- Weather can rule out any outdoor shot at short notice
- If you're after high-speed traffic, you won't find it in Ireland
Updated: August 2026 – If you come to Dublin Connolly from central Europe, you notice the difference before the first train even arrives: the tracks are too wide. Ireland runs on a 1,600 mm track gauge, and because the island has no continuous network with the continent, practically the entire fleet is a home-grown design. Add to that a suburban system with DC overhead wire, diesel operation on every other line, and the island’s only cross-border train connection.
This page tells you which viewpoint works here, why you can scrap your freight-train plans, and how to fit Dublin sensibly into a bigger trip.
Document Irish trains properly
A fleet you won't see anywhere else - log type, operator and time right there on the platform.
An island with its own track gauge
Irish broad gauge isn’t a curiosity, it’s the reason for everything that makes this station special. Because trains can’t simply be adopted from the continent, there are home-grown designs or specially adapted types here - and not a single train you’d also see in Cologne, Brussels or Amsterdam.
There’s a second special feature too: only the suburban services are electrified, and on DC at that. Everything beyond that runs on diesel. Both are operated by Iarnród Éireann, the state railway of the Republic. At Connolly, electric suburban trains and diesel multiple units therefore stand side by side at neighbouring platforms - a sight that barely exists in this form on the continent any more.
What actually runs here
| Train type | Frequency | Power | Special feature |
|---|---|---|---|
| Suburban services along the coast | dense frequency all day | electric, DC | carries the station’s frequency |
| Regional services towards the north and north-west | individual services per hour | diesel | longer dwell times, good for reading numbers |
| Cross-border service to Belfast | a few train pairs daily | diesel, own rolling stock | the day’s most rewarding sighting |
| Empty stock and positioning moves | irregular | mixed | often at off-peak times |
| Freight traffic | very rare | diesel | individual routes, unpredictable |
Take the last row seriously. Ireland has lost almost all of its rail freight over the decades; what remains is a handful of movements to the port. If you arrive expecting freight trains, you’ll be disappointed - Doncaster is the right place for that, not Dublin.
One more thing shapes how you read the station: Connolly is operationally split in two, and you should understand that before you pick a spot. Part of the tracks end in dead ends - that’s where trains for the north and north-west are prepared, and where the Belfast service stands too. The other part runs through and continues via the elevated line straight across the city centre - that’s where the electric suburban traffic runs.
In practice that means: you can’t cover both from one spot. At the terminal tracks you get long dwell times and calm conditions for reading numbers, but not much movement. At the through tracks there’s always something happening, but you get barely a minute per train. The sensible split, then, is to switch roughly halfway through your time - and because the distances within the station are short, that costs you almost nothing.
One detail on the side that many overlook: the station sits on a viaduct above street level. From the platforms you therefore look out over the rooftops of the district, which makes shots from the platform end feel noticeably more open than at a station at ground level.
The calculator: what does your time window get you?
How many trains will you see at Connolly?
A rough guide for a viewpoint covering both groups of tracks. If you only stand at the terminal tracks, you'll come out noticeably lower.
The better viewpoint is outside
Connolly itself is a solid working station, but not a subject in its own right. The shots come from the elevated line that crosses the city centre on a steel viaduct: trains over the water, the quays in front, the city behind. It's a few minutes' walk to get there. Building your own photo spot map describes how to find such viewpoints in advance instead of searching on site.

Irish broad gauge or a British class number - your logbook stays one and the same, wherever you're standing.
A Dublin railway day that works
Start during rush hour
In the morning, suburban, regional and Belfast services overlap. That's the only period with real density.
Cover both groups of tracks
Start with the through tracks for suburban traffic, then the terminal tracks for the long-distance trains. They work in completely different ways.
Head out to the elevated line
For the photos, go to the quays beneath the viaduct. Free, with no barrier, with the city as a backdrop.
Take in the tram
The tram stops right outside the station. If you're documenting local transport anyway, you have three systems in one place here - tram networks in Europe has pointers on that.
Move on to the second station
The western long-distance station serves completely different routes. You're there in a quarter of an hour by tram.
Getting there, tickets and house rules
Connolly sits at the eastern edge of Dublin’s city centre and is reachable on foot, by tram and by bus; the central coach station stands right next to it. From the airport you’re there by bus in about half an hour. If you’re staying several days, a top-up local transport card or contactless payment works out cheaper than single tickets.
The platforms are accessed via ticket barriers, so you need a valid ticket; if in doubt, ask at the service point. Photography for personal use is common here too and rarely questioned - but the operator’s house rules apply, and staff instructions are binding. Fully open to the public are the forecourt, the tram stop and the riverside paths beneath the elevated line, where the better photos come from anyway.
Are you ready for a session abroad?
- Local transport card or contactless payment sorted
- Weatherproof jacket - Irish showers arrive without warning
- Time window set during rush hour
- Second station included in the plan
- Traintrack app installed and logged in
- Expectations for freight traffic adjusted
- Return journey or ferry connection checked
Who Dublin Connolly is the right place for
Connolly suits you if …
- you want to see trains found nowhere else
- track gauges and electrification systems interest you
- you document local transport as a whole
- you're in Dublin for a few days anyway
Combine it with a second destination if …
- you need more traffic – then add the second Dublin long-distance station
- you're travelling on – then take the ferry to Crewe and beyond
Go elsewhere if …
- you want to document freight traffic
- you're after high-speed trains – Brussels-South is the place for that
- you expect a high frequency – then Cologne Hauptbahnhof is a better bet
Safety on narrow platforms
Connolly is a working station on an elevated section, with narrow platforms and heavy rush-hour traffic. The rules are the same as everywhere else, and they matter especially here because space is tight: stay behind the marking, keep door areas clear, don’t set up equipment in the flow of passengers.
Tracks, viaducts and operational structures are off limits
Entering tracks, embankments or the elevated line structure is a criminal offence and life-threatening - on top of that, the suburban service runs under DC overhead wire, where even getting close is dangerous. All the viewpoints named on this page lie on platforms or public paths. Safe distances from the track explains why the margins are set the way they are.
Conclusion
Dublin Connolly isn’t a station where you rack up records. The frequency is lower than what you’re used to from a central European main station, there’s practically no freight traffic, and photographically the station itself stays unremarkable. What makes it worthwhile is how different it is: a track gauge found nowhere else, its own fleet, its own electrification system, and the island’s only cross-border connection.
For a trip, that means Dublin is a building block, not a destination. Combined with York, Crewe, or - on the continent - Amsterdam Centraal, that gives you a loop where you see four different railway systems in a week. Tracking trains live across Europe explains how to keep track of it all.
In brief
Little traffic, no freight, middling photo conditions - and still worthwhile, because almost nothing here is like the continent. Two to four hours is enough; the better photos come from the elevated line over the river.
Build a logbook that crosses borders
Irish broad gauge, British classes, central European classes - all in one collection, neatly sorted by location.
Summary
- Connolly isn't a station of big numbers, but of a special combination: its own track gauge, its own fleet, and a single international connection.
- Suburban traffic carries the frequency, while the long-distance and Belfast services deliver the sightings you can't get anywhere else.
- Photographically the station itself is middling; the good shots come from outside, on the elevated line over the river.
- For spotters from German-speaking countries, Dublin is interesting mainly because almost nothing here is like it is at home.
Frequently asked questions
Why does Ireland have a different track gauge?
Ireland's railways agreed on 1,600 millimetres in the mid-19th century, considerably wider than the standard gauge used on the continent. Because the island has no continuous network with Great Britain, it stayed that way. For you, that means every train is either an Irish special build or a design adapted to this gauge - a fleet with no European equivalent. Identifying train classes describes how to work through vehicle types systematically.
What's the difference between Connolly and Heuston?
Dublin has two major long-distance stations. Connolly serves the north and north-west as well as cross-border traffic, plus the electric suburban services along the coast. The second station, in the west of the city, serves the routes to Cork, Limerick and Galway. Both are connected by tram - if you have a whole day, visit both.
What is the DART?
The DART is the electric suburban system along the Dublin coast, in operation since the 1980s and equipped with 1,500 volts DC. Anything that doesn't run on these lines operates on diesel in Ireland. That exact contrast is what makes Connolly interesting: electric and diesel operation stand side by side here.
What is the Enterprise service?
That's the name of the through service between Dublin and Belfast - the only cross-border train connection on the island of Ireland. It's jointly operated by the railways of both parts of the island and runs with its own rolling stock. In terms of trains, it's the most rewarding thing you'll see at Connolly; the fleet is being modernised in stages.
Is there freight traffic in Ireland?
Very little. Rail freight has shifted almost entirely to road over the decades; what's left is a handful of routes, mainly container and raw-material traffic to the port. If you want to document freight trains specifically, don't try it in Ireland - at Doncaster you'll see more in one afternoon than here in a week.
Do you need a ticket for the platforms?
Yes, access is via ticket barriers. If in doubt, ask at the service point - staff are approachable, and photography for personal use is common here too. The riverside quays, the forecourt and the tram stop are freely accessible. For the legal background, see is it legal to photograph trains?.
Where do you get the better photos in Dublin?
Not at the station, but on the Loop Line - the elevated route that crosses the city centre on a steel viaduct. From the public riverside paths you get trains over the water with the city as a backdrop. One stop further along the line there's also a narrow elevated halt with daylight and head-on arrivals.
How much time should I plan for?
Two to four hours is enough for Connolly itself. Add the second Dublin long-distance station and the tram, and you'll fill a whole day. Because the frequency is lower than on the continent, it's worth timing your visit for rush hour. Planning a station spotting tour explains how to structure a session like this.
Is Dublin worthwhile for spotters from German-speaking countries?
Yes, but for a different reason than usual. You come here not for the volume, but for how different everything is: an unfamiliar track gauge, its own fleet, a different electrification system and a single international connection. If you're after sightings beyond the central European standard, this is exactly that - Interrail for railway fans has ideas for planning the trip.
How do I combine Dublin with a trip to Britain?
Ferry connections to North Wales or north-west England make Dublin easy to add onto a British trip. From the Welsh coast you're quickly at Crewe, and from there you reach York or London Paddington within a few hours.

Spots nearby
Crewe
Crewe isn't a town with a station, it's a station with a town built around it. Half a dozen routes converge here on the West Coast Main Line, a huge freight yard lies just to the south – and the same sort of people with a notebook have stood on the platforms for generations.
Junction stationLondon Paddington
Paddington is London's most elegant train shed: three cast-iron spans from the era of Isambard Kingdom Brunel, plus the starting point of the Great Western Main Line. Since the Elizabeth Line arrived, two completely different rail systems run here under one name.
Junction stationYork
York's platform hall follows the curve of the track – which is why you see something here you see nowhere else: a train sweeping through a bend beneath a vaulted roof. Add the East Coast Main Line, a junction towards Leeds, Scarborough and Hull, and the National Railway Museum right next door.
Junction stationAmsterdam Centraal
Amsterdam Centraal stands on three artificial islands in the IJ, has one of the best-known station façades in Europe, and channels all of the Netherlands' international traffic. For spotters it's also the country's most difficult major station – because of the crowds.
