Fel rhan o’m hymrwymiad i wella perfformiad gwasanaethau trên Cymru, rwy'n cwrdd yn rheolaidd â swyddogion Network Rail a Threnau Arriva Cymru, a hynny mewn cyfarfodydd ar wahân, i drafod y materion sy'n eu hwynebu ar hyn o bryd a’u cynlluniau ar gyfer y dyfodol.
As part of my commitment to drive improved performance of train services in Wales, I regularly meet with Network Rail and with Arriva Train Wales on a separate basis to discuss current issues and future plans.
