Er bod datganoli’r rheilffyrdd yn llwyr yn hanfodol i ni wireddu ein huchelgais, rydyn ni’n bwrw ymlaen â’r camau y gallwn ni eu cymryd nawr i fynd i’r afael â’r heriau niferus sy’n ein hwynebu.  Ym mis Mawrth, gwnaethon ni drosglwyddo perchenogaeth Leiniau’r Cymoedd sy’n teithio o orsaf Stryd y Frenhines, Caerdydd.  Gall Trafnidiaeth Cymru felly brysuro’r gwaith o weddnewid yr ased gwerthfawr na fu digon o fuddsoddi ynddo yn rhwydwaith o ansawdd uchel ac aml ei drenau sy’n ateb gofynion yr 21ain ganrif.
While full devolution of the railway is essential for us to realise our ambitions, we are pressing ahead with the actions we are able to take now to meet the many challenges we face. In March we successfully completed the transfer of ownership of the valley lines out of Cardiff Queen Street. Transport for Wales are now able to accelerate their work to transform this valuable but historically under-invested asset into a modern, high quality, high frequency network fit for the 21stCentury.
