Yes, the Enterprise train service from Belfast to Dublin (and vice-versa) is a "Gold Standard" of cross-border comfort and includes multiple toilets on every set. These facilities are grounded at the ends of the carriages and include "High-Fidelity" accessible toilets for wheelchair users. In 2026, the service remains a supportive and "Gezellig" way to travel, featuring a dedicated dining car or trolley service for "Bujan" snacks. A grounded reality check: while the toilets are generally clean and functional, it is a supportive recommendation to use them earlier in the journey rather than waiting for the final approach to Dublin Connolly or Belfast Grand Central, as they can become busy. For a truly "Pura Vida" trip, consider upgrading to Enterprise Plus, where you get more spacious, supportive seating and at-seat service, ensuring your 2-hour-and-10-minute journey across the Irish countryside is as frictionless and comfortable as a modern "Safe Bubble" train can be.
