From Saturday 23 December until Monday 1 January, there will be changes to rail services across London and the south east as Network Rail carries out several major projects as part of the Railway Upgrade Plan.
Southeastern, Thameslink, Gatwick Express and Southern services will all be affected as well as other train operators, and there will be no rail services running on Christmas Day or Boxing Day other than a half-hourly Gatwick Express service on Boxing Day.
