Is the London Overground affected by the June 2026 tube strikes? Essential information about RMT industrial action next week

Two more days of industrial action are set to hit London next week – so it’s time to get journey planning. London Underground drivers who are RMT union members will walk out for 24-hour periods on Tuesday (June 2) and Thursday (June 4). 

The strikes are part of an ongoing dispute between the union and TfL. The latter is offering a condensed four-day working week, which could mean longer shifts for drivers on the Underground network. The union claims the change will increase fatigue and compromise safety, though TfL says proposals would be voluntary. 

The walk-out will cause major disruptions to the Underground lines next week, but how are services on the Overground expected to fare? 

June 2026 Tube Strikes: How to get around London during RMT industrial action.

When are the June 2026 tube strikes?

Two 24-hour periods of industrial action on the tube are planned for June, taking place on:

  • Tuesday June 2 (midnight to 11.59pm)
  • Thursday June 4 (midnight to 11.59pm)

Some disruption should be expected on the mornings of Wednesday June 3 and Friday June 5 as services get back to normal.

Strikes originally planned for later in June have been cancelled. However, unless the dispute is resolved it is likely more industrial action will be announced in the summer.

Will the Underground strikes affect the Overground?

TfL has said that the entire Overground network will run as usual during the June strikes. However, it’s likely to be significantly busier than usual with Londoners swerving the Underground. 

Interchange access is expected to be reduced at stations which also serve the Underground.

Full list of London Overground lines

Here are all the Overground lines you’ll be able to travel on during the industrial action.

  • Liberty line
  • Lioness line
  • Mildmay line
  • Suffragette line
  • Weaver line
  • Windrush line

How long will the industrial action last?

This current period of strikes began in April and is due to end following the June 4 walk-out. Of course, should TfL and RMT come to an agreement, it could come to an end sooner. 

If the two sides are unable to find a compromise, we could see more strikes announced for later in the summer. 

Is the Elizabeth line running during the June strikes?

Yes. Drivers on the Lizzy line will still be working, so you’ll be able to use the line as normal during the strike action.

Will trains and buses be disrupted?

Trams, buses and the DLR are also due to run as normal. National Rail services are also expected to be unaffected, although all of these services are likely to be more crowded than usual.
