A major railway line for cross-border services between Glasgow and Carlisle is closed because of a fallen tree.
No trains have run between Glasgow and Carlisle since Monday night when the tree fell on to overhead electric wires between Lockerbie and Carstairs.
Avanti West Coast and TransPennine Express services are disrupted.
Some Avanti West Coast services between Glasgow Central and London Euston are starting and ending at Carlisle.
Disruption is expected to continue until 2pm on Tuesday.
Passengers are being permitted to use their tickets with certain other operators, such as LNER on the East Coast Main Line.
Network Rail Scotland said in a statement to passengers: “We’re near Beattock on the West Coast Main Line, carrying out repairs to overhead wires damaged by a fallen tree last night.
“Work is well underway, and we’re on target to reopen the line approximately 11.30am.”
