Back in 2010 we lost our direct connection to Charing Cross, admittedly only at evenings and weekends. These days many people change trains at London Bridge to continue on to Waterloo and Charing Cross.
In 2015/6, as part of the 'improvement works' at London Bridge station, Network Rail plan to have all trains to/from Waterloo East and Charing Cross running through London Bridge without stopping.
Southern trains will continue to terminate at London Bridge with the interchange option for the Northern and Jubilee Line and Canon Street trains, but not Waterloo or Charing X.
My job is currently based in Waterloo, so the easy change at London Bridge is excellent for me and significantly cheaper than using the underground to get to work (even though it would be quicker). I suspect that many people like me will need to switch from Southern trains to East London Line to get to work.
I'm interested to find out how this will impact other people who currently travel on the London Bridge to Charing Cross service. Will there be another big shift from Southern to ELL, and can the four carriage trains handle the extra demand?
