The entire London Underground network is due to be shut down by this week's strike, the most severe disruption to the tube network since 2002.
All 11 lines - Bakerloo, Central, Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly Victoria and Waterloo & City - across 270 stations will be closed for 24 hours from late afternoon on Wednesday.
Members of the Rail, Maritime and Transport (RMT), Unite and Transport and Salaried Staff Association (TSSA) will walk out on Wednesday for 24 hours from 6.30pm, and members of Aslef, which represents tube drivers, will walk out for 24 hours from 9.30pm.
But disruption could begin earlier because unions have told staff not to clock on for shifts which end after the strike has started. London Underground have said that the network will be shut for the whole of Thursday, 9 July.
District Light Railway, London Overground and Transport for London (TfL) rail staff are not on strike and services should be running as normal, though they are expected to be busy. There will be 200 extra buses and additional river-boat services, and National Express are putting on more coaches going into the capital.
Finn Brennan, Aslef's lead negotiator, told The Independent last week: “We are anticipating it will be a complete shut-down of the entire underground system.”
RMT workers for First Great Western, which runs trains between London Paddington and Reading, Oxford, Bristol and South Wales, are also due to strike, for 48 hours from 6.30pm on Wednesday, because of concerns over safety, job losses and buffet services.
