TfL is warning that there's likely to be disruption on the Hammersmith & City and Circle lines tomorrow and Friday as tube drivers go on strike.
Drivers on the lines who are members of the RMT union have voted to strike for 24 hours from 9.30pm from tomorrow (Thursday). If the action goes ahead it will mean no Hammersmith & City line service, and a very limited service on the Circle line.
London Underground and the union are in talks to resolve the local disputes which have resulted in the vote to take action.
People who use the lines are advised to check before they travel at tfl.gov.uk/tube-strike.
