AMs agreed unanimously to support electrification of the north Wales coast line in a Liberal Democrat debate on the matter on 9 January 2012.
In July 2012, the UK Government announced that the Great Western line between London and Swansea would be electrified.
The Department of Transport also said commuter lines in the south Wales valleys would be electrified.
Following the announcement by the Coalition Government of its intention to electrify the south Wales mainline, the Welsh Liberal Democrats are keen for the Welsh Government to start work immediately on developing a business case for the north that can then be submitted to the UK Department of Transport.
The motion received full support in the chamber.
The party believes that all streams of investment must be explored, including the newly-established 50bn Connecting Europe Facility which aims to finance energy, communication infrastructure and transport links.
North Wales AM for the party, Aled Roberts argued that cross-party co-operation secured the electrification of the railway in south Wales and the same co-operation is needed to ensure the same outcome in the north.
In response Local Government Minister Carl Sargeant emphasised that the government was working towards a modern railway network for Wales and would work with all relevant partners to achieve electrification of the north Wales coast line.
