Nevertheless, I would not want to see commuters unable to go about their business, and clearly there was major disruption to the network in the Cardiff area on Tuesday 22 March.
Serch hynny, nid wyf am weld cymudwyr yn cael eu rhwystro rhag mynd i’w gwaith, ac mae’n amlwg y bod y methiant pŵer wedi amharu’n sylweddol ar bobl yn ardal Caerdydd ar 22 Mawrth.
