By the time that Eurostar services became operational through the Channel Tunnel in 1994, it was decided that regional Eurostar services from Manchester (via the West Coast Main Line) and Glasgow (via the East Coast Main Line) to Paris and Brussels were not economic to run, due to their long journey times compared to air travel:  Manchester-Paris and  Glasgow-Paris.
