Several train journeys between Scotland and England have been cancelled or delayed after a train fell on the track in the Borders.
The tree has blocked the line between Carstairs and Lockerbie from around 1.30pm on Tuesday leaving hundreds of travellers facing disruptions to their journeys.
One man, who was travelling on an Avanti West Coast service from Wigan to Glasgow when the incident took place, told STV News: “We had just passed James Jones sawmills in Lockerbie when there was a loud bang and the train started to come to a halt.
“It must have been doing 100mph at the time. It’s seems it hasn’t been as bad as it could have been with the way the tree has fallen on overhead cables.
“The driver apparently saw the tree falling on the line, hit the emergency button and ran out his cab.
“Fortunately it fell on cables and part of tree is on roof. Not much damage to front of train.
“Managed to get electricity restored, the train was getting colder.
Avanti West Coast say all of its services to Scotland on Tuesday are affected.
Arrangements have been made for ScotRail to accept Avant West Coast tickets between Glasgow Queen Street and Edinburgh until further notice.
London North Eastern Railway are conveying passengers between Edinburgh and London Kings Cross in both directions and CrossCountry are conveying passengers between Birmingham New Street and Edinburgh in both directions until further notice.
Arrangements have been made for Avanti West Coast rail tickets to be accepted for these journeys.
The 10.30am London Euston service that was due to arrive in Glasgow Central at 3.16pm has been terminated at Carlisle and will no longer call at Motherwell or Glasgow.
And the 10.43am London Euston service that was due to arrive in Edinburgh at 4.18pm has also been cancelled and will no longer call at Lancaster, Penrith North Lakes, Carlisle, Haymarket or Edinburgh.
