Hundreds of rail engineers are working to repair damaged tracks in the North East of England after torrential rain in the region.
Tyne and Wear Metro network is running a reduced train service, with replacement buses operating between some stations.
Rail services were badly disrupted as rain tore away track beds at Scremerston, Northumberland, and landslides in the Lake District and Scottish Highlands caused more problems.
It led to thousands being stranded as no trains could pass between Newcastle and Edinburgh.
The route has since been reopened, but with journey times extended by 90 minutes.
A normal service is expected to run between London and Leeds today.
