National Rail has warned of major delays in south London, after 'a number of incidents' which are disrupting Thameslink, Gatwick Express and Southern services. A train has been derailed, and passengers were being urged not to travel on the affected routes. Although that warning has now been lifted, disruption is expected to continue for the rest of the day.

Three branch lines in south west England will stay closed until further notice, Network Rail has warned, because floodwater has put structures at risk. Trains have not run between Exeter and Okehampton or Barnstaple since the most recent storms, while the Looe Valley Line has not seen trains since the end of last year.
