Fe wnes i ddatgan ar y pryd, ac mae’n bwysig pwysleisio hynny o’r newydd, bod y math hwn o fethiant pŵer, mewn amgylchiadau o’r fath, yn anarferol. Dywedais hefyd mai Network Rail sy’n gyfrifol am ymdrin â’r materion yn ymwneud â’r methiant pŵer. Nid oes gan Lywodraeth Cynulliad Cymru unrhyw gyfrifoldeb datganoledig dros Network Rail.
I stated at the time, and it is important to re-emphasise, that this type of power failure in these circumstances is unusual. I also said that the issues relating to the failure are within the remit of Network Rail. The Welsh Assembly Government has no devolved responsibility for Network Rail.
