The changes are as a result of major improvement works being carried out as part of the Thameslink Programme and will affect Southeastern, Thameslink, Gatwick Express and Southern services as well as other train operators. There will be no National Rail services running at all on Christmas Day or Boxing Day.
There will be no services to Charing Cross, London Bridge, Waterloo East or Cannon Street during this time and no trains to St Johns, New Cross, Grenwich, Westcombe Park, Maze Hill or Deptford.
A different timetable to normall will be in operation with some services diverted to Victoria, Warleroo and Blackfriars but overall there will be far fewer trains running overall than usual during this time and services are likely to be a lot busier.
Passengers are therefore being advised to prepare in advance for this and to allow more time for their journeys.
Planning some last minute Christmas shopping?
People travelling to central London over these dates are likely to be severely impacted and are advised to make alternative plans to complete their journey.
Going abroad for Christmas?
A reduced timetable will run between Victoria and Gatwick Airport from December 23rd until January 1st 2018 with no trains at all on Christmas Day or Boxing Day although a replacement bus service will be available on Boxing Day. Passengers are advised to allow extra time for their journey.
Train services to other London airports and St Pancras International will also be affected by closures, so please check your journey before you travel.
