37425 passes Troedrhiwfuwch on 16 April 2005 with the 2R30 13:59 Cardiff Central to Rhymney service. The village of Troedrhiwfuwch (between Tirphill and Pontlottyn) was almost completely abandoned in the 1980s, due to fears that the mountain behind the village was moving. Fearing another Aberfan, all the residents were moved out, and all but two houses were demolished.
