Opened as Abergele by the Chester and Holyhead Railway on 1 May 1848, the 'and Pensarn' suffix was believed to have been added when the station was substantially rebuilt in 1883. It became part of the London, Midland and Scottish Railway during the Grouping of 1923. The line then passed on to the London Midland Region of British Railways on nationalisation in 1948. When Sectorisation was introduced, the station was served by Regional Railways although Intercity Sector trains passed through on their way from London Euston and the Midlands to Holyhead. The Privatisation of British Rail led to services being provided by Wales and Borders until 2003, Arriva Trains Wales until 2018, and in the present day, Transport for Wales. The station had been the location of two LMScaravans in 1935 and 1936 followed by three caravans from 1937 to 1939. Nine camping coaches were positioned here by the London Midland Region from 1954 to 1971. It was originally served by loops off the main line in both directions, but the eastbound one was removed in the late 1980s and the main line realigned to pass through the platform. However the westbound one remained in use until early 2017 - it was decommissioned over the weekend of 8/9 January. The loop has now been lifted and the platform extended out to reach the remaining main line. A replacement bus service was provided to Rhyl whilst the work was in progress, as westbound trains were not to call until the work was completed. The platform reopened to traffic on 12 March 2017. As part of the same modernisation scheme, the signal box here was abolished in March 2018, when new colour light signalling was commissioned between Colwyn Bay and Shotton.
The station is now unstaffed and intending passengers must purchase tickets prior to travel or from the conductor on the train. The former ticket office next to platform 2 and the waiting rooms on each side still stand, but are no longer in rail use - waiting shelters are provided for passengers on each platform. Train running information is offered via CIS screens, customer help points and timetable poster boards, along with a payphone on platform 2. Step-free access is available to both platforms via ramps from the road bridge linking them.
