Rydym hefyd yn gweithio gyda Merseytravel i ailagor llinell reilffordd Halton Curve, a fyddai'n gwella cysylltiadau rhwng Lerpwl a Gogledd Cymru, trwy Faes Awyr Lerpwl a Chaer, ac i ystyried yr achos busnes dros gynyddu nifer y gwasanaethau ar y llinell rhwng Wrecsam a Bidston, a dichonoldeb gwneud hynny, yr ystyrir ei gynnwys ym masnachfraint nesaf Cymru a'r Gororau.
We are also working with Merseytravel to deliver the re-opening of the Halton Curve which would improve connectivity between Liverpool and North Wales, via Liverpool Airport and Chester, and to examine the feasibility and business case for increasing frequency on the Wrexham to Bidston line which will be considered for inclusion in the next Wales and Borders franchise.
