Dim ond rhan o'm gweledigaeth ehangach ar gyfer moderneiddio'r rheilffyrdd yw trydaneiddio. Mae gan reilffyrdd ar draws ffiniau swyddogaeth economaidd bwysig o ran manteisio i'r eithaf ar fuddsoddiadau mewn rheilffyrdd yng Ngogledd Lloegr a Gogledd Cymru. Mae fy swyddogion wedi edrych ar ba mor ymarferol yw ymestyn y gwasanaethau ar draws y Pennines o Ogledd Cymru a rydym yn cydweithio â Merseytravel i ddatblygu achos dros wella Halton Curve a fyddai'n gwella'r cysylltiadau rhwng Lerpwl a Gogledd Cymru.
Electrification is only part of my vision for a wider rail modernisation programme. Cross border movements by rail have an important economic role to play to maximise opportunities from rail investments in the North of England and North Wales areas. My officials have examined the feasibility of extending cross-Pennine services into North Wales and we are working with Merseytravel to develop the case for upgrading the Halton Curve which would significantly improve connectivity between Liverpool and North Wales.
