The North Wales Coast Line ((ウェールズ語: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. In April 2006, Network Rail organised its maintenance and train control operations into "26 Routes". The main line through Crewe forms part of Route 18 (The West Coast Main Line). The North Wales Coast Line from Crewe (North Junction) to Chester and North Wales has been designated Route 22 (North Wales and Borders) and this includes the line to Chester from Acton Grange Junction, south of Warrington. The line from Shrewsbury to Chester via Wrexham is Route 14 (South and Central Wales and Borders) (until Saltney Junction). The line is not currently electrified, so Virgin trains have to use their Super Voyagers, which they have done since December 2007. There are no official plans to electrify the line but both the Welsh government and Chancellor George Osborne have indicated that there is a strong case for electrification in the future. The line contains several notable engineering structures, namely Conwy railway bridge across the River Conwy, and Britannia Bridge across the Menai Strait. ==History== The first section from Crewe to Chester was built by the Chester and Crewe Railway and absorbed by the Grand Junction Railway shortly before opening in 1840. The remainder was built between 1844 and 1850 by the Chester and Holyhead Railway Company as the route of the Irish Mail services to Dublin. The line was later incorporated in the London and North Western Railway. Between Chester and Saltney Junction, the line was, from the start, used by trains of the Shrewsbury and Chester Railway later to be incorporated in the Great Western Railway. So important was the line in the 19th and early 20th centuries to passenger, mail and freight traffic between Britain and Ireland that the world's first experimental and operational water troughs were installed at Mochdre between Colwyn Bay and Llandudno Junction. Their purpose being to enable steam engines (especially on the Irish Mail) to collect water without stopping. Later, considerable stretches of line between Chester and Colwyn Bay were quadrupled to increase line capacity but these sections have now been reduced to two tracks. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「North Wales Coast Line」の詳細全文を読む スポンサード リンク
