Belfast passengers are served by two major train stations. One is in the center of the city not far from the Europa Hotel and the Grand Opera; the other is about one-half a mile out. If you plan to catch a bus or train in the heart of Belfast, you will naturally go to the downtown train station. This is the Great Victoria Street Train Station.
At the Great Victoria Train Station, sharing a roof with the Belfast Bus Terminal, you can catch trains to anywhere in Northern Ireland and down south to Ireland. But do note, if you want to meet an arrival from Dublin or Larne, you will have to go to the Central Station. Belfast is part of a major corridor for Northern Ireland Railways (NIR). You can catch a train from Belfast to Derry (Londonderry) via Ballymena. This is a particularly scenic if slow route. You can also go to Bangor. Another popular route is from Belfast to Dublin. You will go through Newry, first. The most reliable service is on the Portadown, to Belfast to Bangor route. Taxis are usually easy to catch outside the Great Victoria Train Station.
