Yule not enjoy the Christmas train service
Joe pointed me in the direction of this announcement about local trains over the Christmas period:
This Christmas, between Saturday 23 December and Monday 1 January 2018 inclusive, there will be closures and changes to services as the Thameslink Programme continues to rebuild London Bridge station and the surrounding railway.
During this time there will be fewer trains into London and your journey will take longer, especially during the three working days (27th -29th December)
From Saturday 23 December until Monday 1 January 2018, there will be changes to rail
services across London and the south-east while Network Rail continues
to transform north-south travel through London as part of the Thameslink Programme.
Southeastern, Thameslink, Gatwick Express and Southern services will all be affected as well as other train operators, with no National Rail services running on Christmas Day or Boxing Day.
Southeastern services will not run to or from Cannon Street, Charing Cross, Waterloo East, London Bridge, Deptford, Greenwich, Maze Hill, Westcombe Park, New Cross and St Johns for the entire period of 23 December to 1 January.
Thameslink services will not run through central London. Trains will be terminating at Blackfriars, Victoria or London Bridge (from the south) and St Pancras International (from the north) from 23 December to 1 January.
A reduced Southern service will operate to and from London Bridge from 23 December to 1 January.
