Ni fydd modd i Drafnidiaeth Cymru na Llywodraeth Cymru roi sylwadau ar elfennau’r broses gaffael tan ddiwedd y cyfnod segur, ac ni fyddaf yn sôn ymhellach am y broses nes dyfarnu’r contract.
Neither Transport for Wales nor the Welsh Government will be able to comment on aspects of the procurement process until the end of the standstill period and will not make any further comment until the contract has been awarded.
