One of the UK's busiest railway lines is blocked after a train hit an object on the track.
South Western Railway is unable to run any services between Woking and London Waterloo.
This affects trains serving Guildford and/or Basingstoke as well, leaving many of them cancelled, delayed or revised until the end of the day
Network Rail said: "At around 5.50am this morning, a South Western Railway train travelling towards London Waterloo struck an object in the Walton-on-Thames area.
"No-one was injured and all passengers were safely escorted from the train; however, the lines through the area are currently blocked while we investigate.
"Early investigations show the front wheels of the train are derailed, therefore it's likely to take us some time to get the railway reopened.
"We're really sorry for the disruption and will update customers on the repairs and timescale for reopening as we know more."
