Wrth gyflawni'r pecyn uwchraddio seilwaith, dangoswyd cydweithio rhagorol rhwng Llywodraeth Cymru, Cyngor Blaenau Gwent, Network Rail a Thrafnidiaeth Cymru. Mae'r gwaith wedi cael ei alluogi gan fuddsoddiadau Network Rail mewn uwchraddio signalau a gwaith adnewyddu pontydd.
The delivery of the package of infrastructure upgrades has demonstrated excellent joint working between Welsh Government, Blaenau Gwent Council, Network Rail and Transport for Wales. The work has been enabled by Network Rail investment in signalling upgrades and bridge replacement works.
