I esbonio'r sefyllfa'n glir ichi, ar ôl ystyried mater addasu'r tâl mynediad yn fanwl, bydd ein cytundeb yn dod â thaliad addasu'r tâl mynediad rhwng Trenau Arriva Cymru a'r Adran Drafnidiaeth i ben. Yn 2017/18. £69.85 miliwn oedd y taliad addasu hwnnw, a rhagwelwyd y byddai'n codi gyda chwyddiant. Bydd Gweinidogion yn cofio y bu sôn llynedd bod Llywodraeth Cymru wedi talu dros £1 biliwn i Lywodraeth y DU dros 15 mlynedd contract gwasanaethau rheilffyrdd Cymru a'r Gororau.
For absolute clarity, following detailed examination of the access charge adjustment issue, our agreement will bring to an end the existing access charge adjustment payment between Arriva Trains Wales and the Department for Transport. In 2017/18 this adjustment payment was £69.85 million, and was forecast to grow with inflation. Members will recall that last year this was reported to lead to a requirement for payments from the Welsh Government to the UK Government totalling over £1 billion over the course of the next 15 year Wales & Borders rail services contract.
