Mae'r cyfyngiadau i'r rhwydwaith rhwng Wrecsam a Chaer yn rhwystrau sylweddol i sicrhau'r cysylltedd a ddymunir ar gyfer Wrecsam.  Rwyf wedi gofyn am gymorth yr Ysgrifennydd Gwladol dros Drafnidiaeth er mwyn cael Network Rail i gynnal gwaith datblygu gyda'r bwriad o ddarparu rhagor o gapasiti yn y rhwydwaith rhwng Wrecsam a Chaer.  Rwyf wedi sicrhau bod achos yn cael ei greu dros y flaenoriaeth hon, yn ogystal â gwelliannau eraill yng Ngogledd Cymru, ac rwyf wedi pwyso arnynt i gynnwys hyn yn Astudiaeth Llwybr Cymru terfynol Network Rail.
The network constraints between Wrexham and Chester present significant barriers to achieving the desired rail connectivity for Wrexham. I have sought support from the Secretary of State for Transport in directing Network Rail to undertake development work with a view to providing further network capacity between Wrexham and Chester.  I have ensured that a case is made for this priority, as well as other improvements in North Wales, and pressed for their inclusion in Network Rail’s final Wales Route Study.
