UPDATE: Disruption has now ended

Transport for London is advising passengers to check before travelling this afternoon due to a number of incidents on London Overground.

There is currently no service on London Overground between Highbury and Islington and Dalston Junction / New Cross Gate as well as between Crystal Palace and West Croydon.

There is also severe delays between Dalston Junction and New Cross Gate due to a passenger being taken ill at New Cross Gate.

TfL says that a Good Service is in operation on other routes, but for passengers who are affected by these delays, TfL says they can use tickets on London Buses to help complete journeys.
