Several key London Underground and Overground lines have been smacked by a double-whammy of closures and delays.

Commuters hoping to board the Northern Line between Finchley Central and Mill Hill East will find no trains running at all as one has broken down. Between Camden Town and High Barnet, meanwhile, there are minor delays as engineers carry out ’emergency’ repairs, TfL says.

‘Significant leaf fall’ will give Piccadilly commuters headaches this morning, with no service between Rayners Court and Uxbridge. A signal failure means minor delays for riders between Acton Town and Heathrow Airport.

Over on the Overground, the freshly-renamed Suffragette Line, which connects Barking Riverside in the east with Gospel Oak out north west, is suffering severe delays. There’s no service at all between Stratford and Willesden Junction as National Rail fixes a fault railway track, with delays hobbling the rest of the line. Mildmay isn’t faring any better in the same areas due to the same issues.
