Govia Thameslink Railway, which operates the Southern, Thameslink, Gatwick Express and Great Northern services, is warning that there will be no trains on the majority of its network next Tuesday (January 30).
This is due to national industrial action by the Associated Society of Locomotive Engineers and Firemen (ASLEF).
Other than limited shuttle services for people travelling to airports, trains will not stop at many stations in north London.
Those affected include Kentish Town, West Hampstead, Cricklewood, Brent Cross West, Mill Hill Broadway, Wembley Central, Harrow and Wealdstone, Finsbury Park, Drayton Park, Highbury & Islington, Harringay, Hornsey, Alexandra Palace, Bowes Park, Palmers Green, Winchmore Hill, Grange Park, Enfield Chase and Gordon Hill.
Limited shuttle services will operate between London Victoria and Gatwick Airport, at Luton to Luton Airport and St Pancreas, and also between London King’s Cross and Cambridge.
A nationwide overtime ban by ASLEF is also set to be in force between January 29 to February 6, which will mean fewer trains will run during this time.
Anyone wishing to travel during these dates are told to check the timetable for the service changes.
Jenny Saunders, GTR’s customer services director, said: “We’re very sorry about the impact this industrial action will have on our customers.
“With no trains on the majority of our network on Tuesday 30 January, we’re asking people to plan ahead and use alternative travel options.
“Whilst there will be trains running on either side of the strike day, the nationwide overtime ban means we are only able to run an amended timetable with fewer trains.
“With other train operators affected on different days, we’re asking customers to check their entire journey each day from Monday, January 29 until Tuesday, February 6.”
