Wrth ddatblygu'r agenda ar gyfer y rheilffyrdd, fel y dywedais yn fy natganiad ar 10 Gorffennaf, rwyf am gael gwerth ein harian a chael y gorau o'n buddsoddiad mewn trafnidiaeth gyhoeddus. Yn hyn o beth, byddaf yn edrych o'r newydd ar brosesau a phenderfyniadau'r prosiect seilwaith i leihau amserau teithio rhwng y Gogledd a'r De a gwella'r rheilffordd rhwng Wrecsam a Saltney.  Ymrwymodd Llywodraeth Cymru i'r prosiect hwn yn 2008 gan roi'r contract i Network Rail, ond cafwyd oedi mawr.
In developing this agenda for rail, as I said in my 10 July Statement, I am seeking to maximise value for money and the impact from our investment in public transport. In that regard, I shall be reviewing the processes and decision making behind the rail infrastructure project to reduce North - South journey times and redouble the railway between Wrexham and Saltney. The Welsh Government committed to this project in 2008 and contracted Network Rail to deliver it, but the project has been significantly delayed.
