Y llynedd, cyhoeddais fy mwriad i ddatblygu achosion busnes ar gyfer cynlluniau gwella rheilffyrdd yn y Gogledd a’r De. Mae’r Athro Mark Barry wedi arwain datblygiad yr achos dros fuddsoddi mewn seilwaith rheilffyrdd. Cyhoeddwyd y crynodeb o’r achos dros fuddsoddi yn yr haf, ac mae’n amlinellu gweledigaeth a chyfres o amcanion trosfwaol ar gyfer prif linellau’r Gogledd, a llinell Wrecsam i Lannau Mersi. Y cam cyntaf yn y broses honno yw datblygu’r achosion strategol ac economaidd dros fuddsoddi yn seilwaith rheilffyrdd Cymru yn yr ardaloedd hyn, a byddaf yn gwneud cyhoeddiad pellach ar y cynnydd rydym wedi’i wneud gyda’r astudiaeth hon. Mae’r gwaith hwn eisoes yn llywio achosion busnes amlinellol strategol y cynlluniau unigol sydd wrthi’n cael eu datblygu gan yr Adran Drafnidiaeth ac rwy’n disgwyl iddynt fframio datblygiad rhaglen fuddsoddi uchelgeisiol, ymarferol a theg ar gyfer y seilwaith rheilffyrdd yng Nghymru.
Last year, I announced my intention to develop business cases for rail enhancement schemes in North and South Wales. Professor Mark Barry has led the development of the case for investment in rail infrastructure. The summary of the case for investment was published in the summer and sets out an overarching vision and set of objectives for the North Wales mainlines, and the Wrexham to Merseyside line. The first step in that process is the development of the strategic and economic cases for investment in Wales’ rail infrastructure in these areas and I will be making a further announcement on the progress we have made with this study. This work is already informing the individual scheme strategic outline business cases currently being developed by the Department for Transport which I expect to frame the development of an ambitious, realistic, and equitable rail investment programme for Wales.
