Yes, the country boasts a rather advanced railway network. Taking a train is definitely a great choice if you need to travel from/to Dublin, as it's the heart of Ireland railway network, but most smaller population centers can also be reached by railway, although a change might be required.

The train system in Ireland, operated primarily by Iarnród Éireann (Irish Rail), is generally considered efficient and comfortable for traveling between major urban centers, though it has limitations for those wishing to explore remote areas. The network radiates mostly from Dublin, with high-quality InterCity services connecting the capital to cities like Cork, Galway, Limerick, and Belfast (via the Enterprise service). Trains are praised for being relatively inexpensive compared to the UK and for offering a stress-free way to enjoy the lush, rolling green countryside without the hassle of driving. Most modern carriages feature ample legroom, free Wi-Fi, and panoramic windows. However, the rail network is not as dense as those in continental Europe; many smaller towns and rural scenic spots—such as parts of Donegal or the Wild Atlantic Way—are not served by rail and require a bus or car for access. In 2026, while it remains a scenic and eco-friendly choice for city-hopping, travelers often find that the limited frequency on secondary lines and the "hub-and-spoke" layout focused on Dublin mean it works best when supplemented by other modes of transport for a comprehensive tour of the island.
