Industrial action across key routes into London are set to bring misery for commuters heading to the capital this week and beyond.
Drivers on the Piccadilly, Hammersmith and City and Circle London Underground lines will strike from Tuesday evening onwards, while conductors on Southern trains will walkout on the same day.
Here's what you need to know ahead of the first in a series of Christmas transport strikes.
What day and time?
Tube strikes will begin at 9.30pm on Tuesday, until around the same time on Wednesday, but Transport for London are advising that disruption will likely begin earlier at 7pm.
Southern strikes will begin on Tuesday morning until the end of Thursday.
What services can I expect and where?
Piccadilly line trains will not run at all, while Hammersmith and CIty and Circle train services will be reduced. This means they will also be more busy as well as running less frequently, with more late notice cancellations also expected.
Other Tube lines are also expected to be busier, especially interchange stations such as Finsbury Park, Victoria and Westminster.
On Southern, several routes will have no trains running at all, though some will still be served by other train companies. They are:
- Clapham Junction to Milton Keynes via Kensington Olympia
- London Bridge and Beckenham Junction via Tulse Hill and Crystal Palace
- Leatherhead to Guildford
- Oxted to Uckfield
- Wivelsfield to Lewes
- Preston Park to Hove
- Wivelsfield to Lewes (via Plumpton)
- Eastbourne to Hastings and Ashford International
- Chichester to Portsmouth Harbour and Southampton Central
- Between Lewes and Seaford
No trains will go to Earlswood, Salfords and Faygate stations
Limited services will run on routes:
- London Bridge – East Grinstead:
- London Victoria – Chichester (via Three Bridges)
- Brighton – Bognor Regis
- Brighton – Eastbourne:
- Redhill to Tonbridge
- Uckfield – London Bridge
- Between Dorking and Horsham
Revised timetables will run on Southern and Gatwoick Express services from Victoria to Gatwick Airport and Brighton.
Thameslink services are expected to run normally, except to Coulsdon South, Merstham, Horley and Redhill, which will be limited, and none will call at closed stations.
Buses only will operate:
- Between Ashford and Hastings
- Between Lewes and Seaford
- Between Uckfield/Buxted/Crowborough/Eridge and Tunbridge Wells/Haywards Heath at peak times
- Between Hastings and Eastbourne
- Between Chichester and Havant
Southern expects all journeys to be disrupted and busier than usual and is advising passengers to travel at different times, not at peak time, and allow more times for journeys.
What are the alternatives?
TfL are putting on enhanced bus services, including a shuttle bus between Hammersmith and Heathrow.
Some other train and bus operators are accepting Southern tickets. Full details here.
