It is the terminus of the Pembroke Dock branch of West Wales Lines from Swansea, 27+1⁄4 miles (44 km) southwest of Whitland.

Originally carrying munitions, the freight branch ran past the station across local streets down to the actual dockside until 1969.

[2] In 2020, the Grade II listed building[3] was regenerated as part of the £24 million Wales Station Improvement Scheme.

[4][5] Transport for Wales Rail is the operator; the station is unstaffed; ticket machine is installed; CIS displays provide train running information in addition to the standard timetable poster boards and public telephone.

The service is named as the Pembroke Coast Express and until 2019, it was operated by InterCity 125 HST sets which have now been replaced by new Class 800 trains.
