Travellers are facing severe disruption as few to no London Underground services are expected from Monday amid walkouts by thousands of workers.
Members of the Rail, Maritime and Transport union (RMT), including drivers, signallers and maintenance workers, launched a series of strikes over pay and conditions.
The action kicked off on Sunday with limited services running but levels of disruption are set to ramp up as Transport for London (TfL) warned there will be few or no services between Monday and Thursday.
No trains will be running before 8am and passengers are asked to complete journeys by 6pm.
There will also be no Docklands Light Railway services on Tuesday and Thursday because of a strike by RMT members in a separate pay dispute.
