In 2026, the rules for consuming alcohol on trains in Belfast depend strictly on the type of service you are using. On local Translink NI Railways services—such as those running to Bangor, Larne, Portadown, or Londonderry—passengers are generally not permitted to carry or consume alcohol. Translink frequently operates "Dry Trains" during high-traffic events or weekends to ensure public safety. However, on the Enterprise service, which runs between Belfast Lanyon Place and Dublin Connolly, alcohol is permitted but with a major caveat: you may only consume alcohol that has been purchased on board from the trolley or dining car. Bringing your own "off-train" alcohol to consume during the journey is prohibited. Passengers who appear intoxicated may be refused entry to any service, and Translink reserves the right to conduct baggage searches if they suspect a breach of these safety bylaws.
