Northern and Bakerloo Lines Disrupted by Signal Failures in London

Commuters across London faced severe disruption on Tuesday morning as signal failures and multiple train cancellations hit the Northern and Bakerloo lines, while a range of other Underground, Overground and rail services reported delays and station closures. Transport for London said engineers were working to fix faults at Stockwell and Tooting Broadway, and urged travellers to avoid the Northern line where possible.

TfL reported no service between Kennington and Morden while crews repaired a fault at Tooting Broadway, and said severe delays persisted on the rest of the Northern line while a separate signal issue at Stockwell was addressed. On the Bakerloo line TfL blamed multiple train cancellations for severe delays. The operator advised passengers that valid tickets would be accepted on London Buses and on alternative rail services including Southeastern, Thameslink and South Western Railway for reasonable diversionary journeys.

Other lines experienced knock-on problems. TfL logged minor or moderate delays on the Metropolitan, Victoria, Waterloo and City, District and Docklands Light Railway at various points, and said the Piccadilly line was recovering after earlier points...
