Just had this fly round on an email:
Thousands of commuters face up to a year of chaos next year when one of the main line stations in London is closed.
London Fenchurch Street will be closing in October 2011 for major redevelopment of the station and surrounding building and TfL have warned that it could take up to a year to complete.
The line which carries thousands of commuters each day will be diverted to nearby Liverpool Street. Network Rail have estimated that the station will be out of action for eight months which would mean that the Fenchurch Street line will be open and ready to share the responsibility of carrying an extra 200,000 people in 2012 for the Olympics. Insiders however fear that Fenchurch Street will not be re-opened until early 2013.
It will also cause chaos for people in Essex who use the line to get to the Docklands as all trains will be diverted to Stratford and Liverpool Street.
