The station is connected to the town centre by a stainless steel pedestrian/cycle bridge named The Celtic Gateway (Welsh: Porth Celtaidd).

The station approach contains a Grade II listed clock turret[3] which was unveiled on 17 June 1878 by Albert Edward, Prince of Wales to mark completion of old harbour extension.

Platform one on the western side of the station is separated from the other two by the ferry terminal buildings and inner harbour and is the one normally used by Avanti West Coast services to London Euston.

The terminal offers covered waiting accommodation, a payphone, a photo booth, a left luggage office, toilets, shops, and a cafe.

A limited number of trains (mostly early morning and late evening) run to/from Crewe, whilst two services operate to Manchester Piccadilly on weekdays only.

Up to September 2014 Stena Line operated a high-speed service to Dún Laoghaire, a suburb 12km south of Dublin City Centre.
