Rwyf wedi gofyn i Dr Elizabeth Haywood gysylltu gydag awdurdodau lleol a busnesau yng Ngogledd Cymru i gefnogi'r achos dros drydaneiddio'r brif reilffordd.
I have asked Dr Elizabeth Haywood to engage with local authorities and businesses in North Wales to elicit support for the case for electrification of the main line.
