Industrial action

The information on this page is correct as of 4 September and is always subject to change so please check back before you travel.

London Underground industrial action

Industrial action is due to take place on the London Underground between Sunday 7 and Thursday 11 September. Strike action is also taking place on the DLR On Tuesday 9 and Thursday 11 September. Full details of the industrial action and the changes to TfL services can be found on the Transport for London website.

Unfortunately, this action will also affect our services on a number of days.

We expect our services to be much busier than usual during the period, particularly on certain routes in and around London: 

Between Balham and London Victoria 
Between London Bridge/Elephant & Castle and London St Pancras 
Between Sutton and London Blackfriars via Wimbledon 
Between Welwyn Garden City/Hertford North and Moorgate or London King’s Cross via Finsbury Park  
Between Hendon and London St Pancras International 
Between Harrow & Wealdstone and Clapham Junction

Below is a breakdown of the affected stations and the service we plan to run each day. Journey planners are up to date for all affected days. Please note, this plan is subject to change at very short notice, so we strongly advise planning ahead and checking your journey again just prior to travelling.

Please also be aware that if this action is called off at short notice, it may not be possible for us to revert to a normal service.

Sunday 7 September

A normal service will operate across our routes, with the exception of any long-planned engineering work changes.

This includes a closure of the Thameslink Core section through central London. This will mean Thameslink services will be terminating at either London Bridge or London St Pancras International, and no services will run across central London. We expect these stations to be particularly busy and there may be queuing systems in place.

Ticket acceptance will be in place as usual on London Underground services for most of the day, however, London Underground services will not be operating after approximately 18:00, so ticket acceptance will not be in place from this time and travel across central London will be severely affected. Ticket acceptance will be in place on London Buses, but this may take significantly longer than usual journeys on our trains or London Underground services.

Details of all planned engineering works, affected routes and ticket acceptance can be found on the Thameslink, Great Northern, Southern, or Gatwick Express.
