 With the alignment having succumbed to heavy encroachment from vegetation, an environmental report would have to be drawn up to limit the potential damage that could be caused to wildlife.Mike Gallop, coordinating the project on behalf of Network Rail, warned that bringing back trains to the line would be "tough".The remainder of the line, between Llangefni and Amlwch, looks set to be preserved as a heritage railway, with Network Rail giving licence to Anglesey Central Railway Limited to begin clearing the overgrown line north of Llangefni.
