The important West Coast Main Line will be closed north of Carlisle until the first week in March due to storm damage. That line is the traditional route for the fastest trains from London to Glasgow. Until March, anyone who wants to take a train to Glasgow should plan on taking an East Coast Main Line train to Edinburgh and connecting to Glasgow by a frequent local shuttle.
