Llandrindod railway station serves the town of Llandrindod Wells in Mid Wales. It is located on the single line Heart of Wales Line and is served by four trains each way on Mondays to Saturdays, two each way on Sundays. Passenger services are operated by Arriva Trains Wales. The facility to pass northbound and southbound trains is used daily. It is also the most used station on the line itself, despite only having four trains a day in each direction (Mon-Sat); this has caused overcrowding on trains, and despite campaigns by local rail groups, the service has not been improved.
