Wikipedia says: “Opened as Abergele by the Chester and Holyhead Railway on 1 May 1848,[1] 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 Railways led to services being provided by Arriva Trains Wales.”
