The North Wales Coast Line (Welsh: Rheilffordd Arfordir Gogledd Cymru), also known as the North Wales Main Line, is the railway line from Crewe to Holyhead. Virgin Trains consider their services along it to be a spur of the West Coast Main Line. The line contains several notable engineering structures, namely Conwy railway bridge across the River Conwy, and Britannia Bridge across the Menai Strait.
