London Bridge disruption expected 'for 18 months'

Passengers using London Bridge station have been told to expect further disruption for the next 18 months.

Many commuters who travel to London Bridge on Southeastern's Charing Cross services will need to find alternative routes.

The disruption is the result of work on the north side platforms of the station, which is part of the Thameslink Programme.

BBC London's Transport Correspondent Tom Edwards spoke to Chris Denham from Network Rail.
