Since the passing loop was lifted all trains use the down platform and the station building on the up platform is today a dwelling. The gated level crossing is controlled by a crossing keeper, who resides in a cabin erected on the up platform. Dyffryn Ardudwy gives its name to the district and to the very extensive beach and sand dunes on the coast nearby that are known as Morfa Dyffryn.HistoryThe station was opened in 1867 by the Cambrian Railway Company as Dyffryn. On I july 1924 it was renamed Dyffryn-on-Sea and on 1 June 1948 was renamed to its present name. The station was destaffed in the 1960s.
