Commuters who use Southern trains will face changes to the times of some services for the next four weeks.

Southern said a new track layout on the approach to London Bridge meant it has been “a challenge” to deliver their new timetable.

From Monday, January 19, changes will be made to some train times during the morning and evening rush hours to help deliver an improved service.

The changes to the below service will remain in place for four weeks before they are reviewed.
