Services

Monday-Saturday daytime, there is a half-hourly service to Cardiff Central southbound and to Treherbert northbound (dropping to hourly in the late evening). There is a two hourly service in each direction on Sundays. On 20 July 2018, previous franchise operator Arriva Trains Wales announced a trial period of extra Sunday services on the Rhondda Line to Cardiff and Barry Island. This was in response to a survey by Leanne Wood and the success of extra Sunday services on the Merthyr Line and the Rhymney Line.

The service from this station is currently (summer 2023) suspended, due to major route upgrade work being carried out at multiple locations as part of the Valley Lines electrification scheme. A replacement bus service is in operation from here to Pontypridd and to Treherbert, calling at all local stations until February 2024
