I'm staying at the Hilton Belfast very near Belfast's Central Station. What is the best train service to Dublin? Thanks.
There's only one train service: the "Enterprise" trains. You can book at both https://www.translink.co.uk/Buy-Online/Enterprise-Buy-Online/ (fare will be in UK pounds) or http://www.irishrail.ie/ (fare will be in euros). Compare which is cheaper.
Thanks Phillip. Do you have to go through customs in Belfast or Dublin on this trip?
