From tomorrow, there will be major changes to rail services to London Bridge as vital but very disruptive work takes place to the track that will in a few years’ time allow a much improved service.
From 20th December to 4th January there will be no Southern or Thameslink services to or from London Bridge.
From 5th January 2015 to January 2018 there will be no Bedford to Brighton cross-London Thameslink trains to or from London Bridge. A reduced off-peak service will run between Brighton and London Bridge and a very limited service will run in the peak.
