Bydd yr aelodau’n cofio i dendrau terfynol ddod i law gan dri chwmni ym mis Rhagfyr 2017. Tynnodd un cwmni ei dendr yn ôl wedyn. Mae Trafnidiaeth Cymru wedi bod yn arfarnu’r ddau dendr arall yn unol â Rheoliadau Contractau Cyfleustodau 2016, gan asesu pob un yn ôl ei ansawdd, cryfder a’i allu i roi prif bolisïau Llywodraeth Cymru ar waith, a nodir yn y ddogfen ‘Gwasanaethau Rheilffyrdd ar gyfer y Dyfodol’.
Members will recall that final tenders were received from three companies in December 2017. One of those tenders was subsequently withdrawn.  Transport for Wales has been evaluating the two remaining bids under the Utilities Contracts Regulations 2016, assessing each for its quality, robustness and ability to deliver on the Welsh Government’s policy priorities, as set out in ‘Rail Services for the Future’.
