The railway station is located at street level at the end of the Llais yr Afon lane near the village centre.

The facilities provided here are limited to a small brick waiting shelter, timetable poster board, digital CIS display and a customer help point.

No ticketing provision is available, so passengers must buy in advance of travel or on board the train.

[3] This is a request stop, whereby passengers have to signal to the driver to board or alight from the train.
