A spokesman for train operator Thameslink says more than half a million litres of water have been pumped from a rail tunnel between Farringdon and St Pancras stations.
Travellers faced severe disruption this morning cased by flooding in the tunnel after a watermain burst on Friday.
A normal service is expected to run tomorrow.
Stuart Cheshire, Passenger Service Director for Thameslink, said: "After four days of disruption we're pleased to confirm that we will be able to operate to our normal timetable tomorrow.
"This has been incredibly frustrating for everyone and I would like to thank our passengers for their patience as well as railway staff for all their hard work."
Crystal Palace fan Angus Mainland is in touch with a girl he met on the train to the match on Saturday - after putting out a Twitter appeal to find her.
19-year-old student Angus forgot to ask the woman for her phone number after meeting her on the way to Southhampton. So he turned to Twitter and sent a message to CrossCountry trains asking for help tracking her down. He says he 'fell in love' with her and the message has been spreading amongst social media users ever since.
And this evening... this happened...
14 year-old Denis Baran who went missing from Walton-on-Thames yesterday has been found. Police said he was located this afternoon.
Crystal Palace fan Angus Mainland had a very enjoyable day on Saturday. Not only did his team win away at Southampton but he met a young woman on the train to the match. They got on so well that the 19 year-old student took a couple of photos of the two of them together:
But Angus forgot to ask the woman for her phone number. So he turned to Twitter and sent a message to CrossCountry trains asking for help tracking her down. He says he 'fell in love' with her and the message has been spreading amongst social media users ever since.
It was a weekend of FA Cup shocks but if you somehow guessed the winning teams, you could make yourself a tidy pile of money.
Londoner Rosie Leigh did just that after managing to pick the five winners out of five Fourth Round matches. Her accumulator bet of £2 earned her £16,087. And as she successfully predicted that the top three teams in the Premier League would all lose - two of them to sides from outside the top flight - Rosie probably deserves it. Here is her bet:
- Reading to beat Cardiff - 7/4
- Bradford to beat Chelsea - 12/1
- Middlesbrough to beat Man City - 8/1
- Crystal Palace to beat Southampton - 4/1
- Leicester to beat Tottenham - 4/1
Police in Enfield are trying to trace a missing 16 year-old girl. Courtney Hazel was last seen on January the 8th. Police say she has links to Tottenham and East Ham and anyone who sees her is asked to call 101.
Network Rail have said that the floodwater in a tunnel between Farringdon and St Pancras has been pumped out but normal Thameslink train services will not resume today. Engineers are now checking that the signalling system in the tunnel has not been damaged and the track is still stable.
Network Rail said normal services are expected to restart tomorrow morning but is advising passengers to check before they leave home. The flooding was caused by a burst water main.
