'Majority' of train services running on timepublished at 11:16 Greenwich Mean Time 17 February 2020
Network Rail says Storm Dennis has had "a significant impact on the railway" after lines were blocked by flooding and fallen trees.
A spokesman said: "The heavy rainfall, combined with already waterlogged ground conditions, has led to flooding in a number of areas across the network.
"Our engineers have been working in extremely difficult conditions throughout Sunday and overnight to clear the tracks and keep passengers moving."
He said "the majority of services are now running as scheduled" but urged anyone travelling over the next couple of days to check before they travel.
