Flooded tracks have forced train operators to cancel services between Cumbria and Scotland in a day of disruption on the rail network caused by strong winds and heavy rain.
National Rail said flooding between Penrith North and Lockerbie meant all lines were earlier blocked.
Network Rail Scotland tweeted images of the rails about a foot under water and said five trains had been trapped between Lockerbie and Carlisle.
But at around 2.30pm, Network Rail Scotland said the line could be open to southbound traffic only subject to a 5mph speed limit, allowing the stranded trains to move.
Passengers travelling between Carlisle and Glasgow Central or Edinburgh had been advised not to travel, with major disruption expected until at least the end of the day.
It has been a day of chaos across the network, with many routes subject to severe delays due to debris on the tracks.
Forecasters say heavy rain and thunderstorms across northern England and Scotland would continue for the rest of the day, with further heavy rain forecast until about mid morning on Sunday.
The yellow weather warning across almost all of Scotland and northern England will come to an end at midnight, but a yellow rain warning will be in force until 10am on Sunday in the Glasgow area.
