Pa gamau y mae Llywodraeth Cymru yn eu cymryd i gefnogi teithwyr yr effeithir arnynt gan atal neu newidiadau i'r gwasanaeth bws X10 rhwng Abertawe a Chaerdydd, a pha drefniadau trafnidiaeth amgen sy'n cael eu hystyried i sicrhau trafnidiaeth ddibynadwy, fforddiadwy a hygyrch rhwng y ddwy ddinas?

Whilst we were disappointed that the commercially operated X10 coach service which linked Swansea and Cardiff has been withdrawn: the two cities continue to be connected by alternative direct and frequent rail and express coach services throughout the day.

We have introduced new trains operating between Swansea and Cardiff thanks to our £800m investment in new rolling stock. These trains offer improved accessibility, capacity and comfort for passengers and have helped Transport for Wales to deliver sustained performance improvements. 

We are working closely with the UK Government to improve the railway infrastructure that it is responsible for in Wales, including the South Wales Main Line. Network Rail has already completed a major signalling upgrade at Port Talbot West, which has helped improve the resilience and reliability of services through Swansea. (Saesneg yn unig)
