I was looking at RealTimeTrains entries for Aberdare today and noticed that there are still regular paths allocated between Hirwaun (Tower Colliery) and Aberthaw Power Station. These coal trains finished in 2017 and both the colliery and the power station are now closed. Why is the path still allocated? Is it just that it stays in the system until the owner relinquishes it or there's a major recast?
