A good service has resumed on a busy overground line following rush-hour delays caused by a signal failure.

A number of trains on the Chingford to Liverpool St were cancelled this morning due to a signalling issue at Hackney Downs.

The 7.57am from Chingford to Liverpool St was cancelled and two trains running in the other direction were either cancelled or did not stop at stations.

Transport for London (TfL) are now reporting a good service on the London Overground line.
