Today’s strike will run until 11:59pm. Here’s what to expect:
No service is expected on the Circle line, the Piccadilly line, the Metropolitan line between Baker Street and Aldgate, and the Central line between White City and Liverpool Street.
Other lines, including the Elizabeth line, DLR, London Overground, buses and trams, will be running as normal but are likely to be busy.
Commuters are being advised to expect disruption to journeys, with services starting late and finishing early.
TfL says travellers should complete their journeys before 9pm.
