Ddoe, bu i aelod consortiwm cynigydd arall lwyddo i brynu y rhan fwyaf o gwmni Carillion Rail gan y diddymwr.  Er bod hyn wedi diogelu nifer o swyddi yn Carillion Rail, yn anffodus roedd yn golygu nad oedd ARC yn gallu sicrhau bod ganddynt y capasiti angenrheidiol i fynd ymlaen.  Nos Iau yr 22ain Chwefror, hysbysodd ARC Trafnidiaeth Cymru o'u bwriad i dynnu'n ôl o'r broses.
A consortium member for another bidder yesterday successfully purchased the majority of Carillion Rail from the liquidator. Whilst this has safeguarded a number of jobs in Carillion Rail, it has unfortunately left ARC unable to secure the capability it would need to proceed.   On the evening of Thursday 22nd February, ARC informed Transport for Wales of its intention to withdraw from the process.
