as of now these strikes are going ahead.
Current guidance from Transport for London is
... all quoted from an email from them ....
The ASLEF, RMT, Unite and TSSA unions are currently planning strike action, affecting Tube services. If this goes ahead, we expect the following:
Wednesday 8 July
Tube services will stop running at around 18:00, so please complete any Tube journeys by that time. Services are expected to be exceptionally busy between 16:00 and 18:00. Please travel earlier if you can and allow more time for your journey.
Thursday 9 July
There will be no Tube service all day. Extra bus and river services will run. Other public transport and roads will be much busier than usual, especially during peak hours. Please travel outside the peak times if you can.
Friday 10 July
There may be some disruption during the morning as services resume.
Staff on the bus network, the DLR, London Overground, TfL Rail, Trams, river services, Emirates Air Line and Santander Cycles are not on strike. There is separate strike action by the RMT on First Great Western services from Thursday 9 July for 48-hours. As always, we advise you to check with your train operator or national rail enquiries. All of these services are expected to be much busier than usual.
