The West Coast Main Line has been closed between Scotland and England because of flooding on the tracks.
Network Rail Scotland says five trains are currently trapped or blocked between Lockerbie and Carlisle – and in places, water levels are a foot above the rails.
In a series of tweets, the group said the flooding was caused by water from an adjacent field running onto tracks.
@NetworkrailSCOT said: “@VirginTrains trains & staff on the ground are advising alternative travel options & ticket acceptance is in place with other operators
“Inspection has shown that flood water on south bound line is not as bad as on north bound line. We are able to open line for south bound traffic only – all be it with a 5 mph speed limit. North bound trains will head back to #Carlisle.”
