Two trains in Ystrad Rhondda railway station There is a 270 metre long section of double track through Ystrad Rhondda station. A few tens of metres on each side of the station, the route becomes single track. There is a token system in operation to prevent two trains occupying a single track section at the same time. Before the northbound train on the left can proceed along the single track section to Treherbert, the driver must obtain the token from the driver of the southbound train stopped alongside the other platform. At the same time, the token for the single track section south to Porth will be exchanged. There are prominent signs at both ends of the platforms to remind drivers of the token system.
