Over the last week I have been in close contact with Transport for Wales and other agencies to ensure that passengers and staff who have been affected by the incident get the support they need.
Rwy'n edrych ymlaen at weithio'n agos gyda Llywodraeth Cymru a rhanddeiliaid eraill, ac at eu helpu i ddarparu system drafnidiaeth integredig, hygyrch a chynaliadwy.
