Tube drivers are staging a 24-hour walkout in protest at relocation plans.
The strike began at 21:00 GMT on Tuesday and services are not expected to return to normal until Thursday.
The Central, Waterloo and City lines have been affected.
Tube bosses have responded to the action by calling the strike ‘unnecessary.’
Meanwhile, Southern Railway conductors are set to walk out on Wednesday.
They are striking over a long-running dispute around the role of train guards.

London among global capitals to receive free emissions-cutting technology
London could be the site of a radical new trial of emissions-cutting technology.
Technology firm Tantalum, which specialises in connected cars, is offering one city the chance to install its device for free on at least 1,000 vehicles.
This would provide Transport for London with real-time data on the CO2 emissions produced by a vehicle, allowing them to reward conscientious driving positively and punish behaviour that impacts negatively on the environment.

Eastenders racism storyline divides viewers
A recent Eastenders’ episode which tackled racism in London has been criticised by some viewers.
In a Brexit-themed plot the words ‘Poles go home’ were graffitied on the Queen Vic after a Polish themed night at the pub.
But EastEnders’ scriptwriter Leo Richardson defended the story, saying that racism is a very real problem for Polish people in the capital after June’s referendum.
This troll. Criticising the show I work on because it did a story about the very real racism Polish people have experienced post-Brexit. 🚮 https://t.co/Mek11gIfmu
