Services resume on Glasgow to London train line

Trains between Glasgow and London are running again after hours of disruption caused by a tree falling on overhead lines in southern Scotland.
Network Rail said work to repair the lines damaged near Beattock in Dumfries and Galloway has been completed and they are working with train operators "to get services moving", but disruption may still impact services from Glasgow and Edinburgh to Carlisle until 19:00.
Avanti West Coast said lines between Lockerbie in Dumfriesshire and Carstairs in South Lanarkshire had reopened and their services were now operating as normal.
Some services scheduled to start in Glasgow earlier began in Preston, Lancashire, with engers experiencing delays.
National Rail said a fault with the signalling system caused further disruption.
Liverpool Lime Street and Manchester Airport services to Glasgow and Edinburgh had also been affected by the closed line.
engers waiting overnight on the Caledonian Sleeper service, including BBC political editor Chris Mason, were told in the early hours of the morning that they had still not left Glasgow Central because a tree had come down on the line.

A statement from Avanti West Coast said: "Lines have now reopened north of Carlisle, after earlier damage to overhead electric wires caused by a fallen tree.
"Trains to and from Glasgow Central and Edinburgh may still be delayed or revised while the service recovers, so please still check before you travel."
Ticket holders were advised that they could travel on alternative services on the East Coast Main Line for no extra cost, or get a refund.
Tickets for journeys with delays of more than 15 minutes are eligible for compensation or refunds.
The Aberdeen to Inverness railway line was also closed earlier because of a fallen tree between Dyce and Kintore, as Scotland faced a band of wind and rain moving eastward from the Atlantic overnight.
Gale-force gusts
BBC weather presenter Christopher Blanchett said there were gale-force gusts of up to 55mph (89km/h) around Lockerbie on Monday night caused by a deep area of low pressure to the north of Scotland.
"The peak of the winds across South Lanarkshire, Dumfriesshire and the Borders was between 21:00 and midnight," he said.
"During the early hours, a gale force gust of 49mph was also recorded at Dyce in Aberdeenshire.
"With trees in full leaf at this time of year, they act like a sail and are more easily caught and toppled in high winds.
"Gales were also recorded at many exposed coastal locations in the west, as well as the Hebrides and the Northern Isles."
