Delays hit two London Underground lines after train cancellations

Passengers face disruption on the London Underground and the railway line between Liverpool Street and Stansted Airport.

The morning rush hour is off to a sticky start after delays across the Piccadilly, Northern and Victoria lines. Part of the DLR has also been suspended.

The Northern line has minor delays between High Barnet and Camden Town southbound only due to a shortage of trains. The Piccadilly line has minor delays due to a shortage of trains, while the stretch between Rayners Lane and Uxbridge remains suspended.

Elsewhere, Stansted Express and Greater Anglia have issued a ‘do not travel’ warning between Cheshunt and Broxbourne after major disruption.

All lines are blocked because of a fault with the signalling system which is causing up to 60-minute delays on the route. While all lines have reopened, disruption is expected until 10am.
