Llangadog railway station serves the village of Llangadog near Llandeilo, Carmarthenshire. The station is on the Heart of Wales Line 36+1⁄2 miles (59 km) north east of Swansea. The station is located at street level at Station Road beside the River Brân. The Garn Goch Iron Age hill fort is about three miles away from this station. All trains serving the station are operated by Transport for Wales. Like several others on the line, it has an automated half barrier level crossing at one end (in this case the northern one). The barrier sequence for northbound trains has to be initiated by the train crew, so the booked stop here for these is a mandatory one. Southbound trains trigger the crossing using a treadle on approach, so only have to stop here on request.
