A major rail route connecting Scotland and England was blocked by flooding on Thursday.
The West Coast Main Line was closed between Carlisle and Lancaster following recent downpours, but reopened around midday.
Services run by Avanti West Coast from Glasgow and Edinburgh to London Euston were affected, as well as trains operated by Northern and TransPennine Express.
A Network Rail spokesman said: “As predicted, the very heavy rain overnight in Cumbria and north Lancashire has flooded parts of the West Coast Main Line.
“Because fast moving floodwater can undermine the railway’s foundation stones, trains were brought to a stop while our engineers made sure the railway was safe for passengers.
“The West Coast Main Line is open again but with some services delayed people are advised to check National Rail Enquiries or with their train operator for the latest travel information.”
