Southern have put up a strike message, noting that they aren't actually on strike:
Industrial action
Last updated: 14 June
Nationwide rail strikes have been called by the RMT union at Network Rail and by other train operators to take place on Tuesday 21, Thursday 23 and Saturday 25 June. Although our colleagues are not on strike, this national action will severely affect all journeys on Southern, Gatwick Express, Thameslink and Great Northern between Tuesday 21 June and Sunday 26 June. We’re really sorry if this affects your journey plans.
Between Tuesday 21 June and Sunday 26 June inclusive, please only travel if your journey is absolutely necessary, and expect disruption.
As this Industrial Action is affecting the whole country, we will be unable to provide alternatives such as replacement buses and ticket acceptance with other local rail and bus operators. We recognise that it will be very difficult to travel and our advice, regrettably, is to travel only if your journey is absolutely necessary.
Tuesday 21, Thursday 23 and Saturday 25 June
Many stations and routes will be closed. Trains will only be able to run during limited hours and will finish in the late afternoon. This means, if you do have to travel, you should carefully check the first and last train for your station. Expect these trains to be very busy.
Please be aware that Transport for London are also expecting Tube strikes on Tuesday 21 June. Visit the Transport for London website for more information.
We anticipate National Rail journey planners for these days will be updated on Friday 17 June.
Wednesday 22 and Friday 24 June
Services will also be severely disrupted and we will run an amended Sunday service, no trains will start running before 0715. This will allow us to run a more reliable and consistent service throughout the day.
We anticipate journey planners for these days will be updated on Saturday 18 June.
Sunday 26 June
Details for the service we plan to run will be updated shortly.
Check again before any necessary journeys before travelling as there may also be changes on the day to the planned service. Ensure you have checked when your last train departs as there will be no alternatives once services end.
We will be adding further detail to the service which we plan to run on these days, as well as some FAQs for our customers to this page tomorrow.
