Bydd Aelodau'n ymwybodol, yn anffodus, bod oedi sylweddol wedi bod o ran y trenau ychwanegol a archebwyd o dan y cwmni blaenorol (o'r enw Class 769), er gwaethaf y sicrwydd gan eu perchnogion Porterbrook, gan roi straen ychwanegol ar y fflyd a gawsant gan Trafnidiaeth Cymru, sydd eisoes yn brin.
Members will be aware that unfortunately, additional trains ordered under the previous operator (known as Class 769) have, despite assurances from their owner Porterbrook, have been significantly delayed, putting additional strain on the already limited fleet which TfW inherited.
