London tube strike
The Tube strike planned this week is set to be the most chaotic industrial action in a decade Reuters

Almost 20,000 London Underground workers are set to take part in industrial action this week in what will be the most chaotic tube strike in a decade. The Rail, Maritime and Transport union, Transport Salaried Staffs Association and Unite members are planning to strike for 24 hours from 6.30pm on Wednesday 8 July in a dispute over the planned "night tube" service and pay.

Last minute talks between Tube and union bosses to avert the action will resume later today (7 July). On Monday, the unions rejected the latest pay offer from London Underground, which included a 2% rise this year and a £2,000 bonus for drivers working on the all-night service.

If the strike goes ahead, there will be no Tube service from late afternoon on Wednesday through to Thursday. So which routes are affected and how bad will the disruption be?

Routes affected

There will be no Tube service at all on the London Underground network. London Overground, DLR, TfL Rail and trams will all operate a normal service. Extra bus and river services will run and roadworks will be suspended, but roads and transport will be much busier than usual so allow more time for your journey.

There will be more cycle hubs during commuting hours – 7am until 11am and 4pm until 8pm. These will be at Soho Square, Houghton Street (near the Strand), Finsbury Square (near Liverpool Street and Moorgate) and Butler Place (between Victoria and Westminster).

For those trying to get to Wimbledon, there are no tube services from Southfields, Wimbledon or other nearby stations. The Tennis Championships remain accessible by bus and National Rail.
