Roedd y rheilffordd rhwng Abercynon ac Aberdâr yn hynod ddrwg ble y bu i lifogydd a thirlithriad ar wahân olygu bod bron 100 tunnell o weddillion yn rhwystro’r lein brysur.  Wedi ymdrech enfawr gan Network Rail, gyda’u tîmau yn gweithio drwy’r nos, ail-agorodd y lein brynhawn dydd Mawrth.
The line between Abercynon and Aberdare was particularly badly affected where flooding and a separate landslip left nearly 100 tonnes of debris blocking the busy route. After a tremendous effort by Network Rail, with its team working around the clock, the line reopened on Tuesday afternoon.
