Commuters heading into London this morning are facing delays after Southern Rail services were suspended ‘until further notice’.
The suspension affects trains running between East Croydon and Clapham Junction into Watford Junction.
It’s also impacting London Overground trains between Stratford and Willesden Junction into Clapham Junction.
Passengers are facing half-hour delays on top of their normal journey time as they’re asked to use an alternative route.
The problem has been caused by a fault with the signalling system, and National Rail warn trains running between the above stations could be cancelled or revised.
Describing the incident, National Rail said: ‘This part of the network uses track circuits to detect trains. If a circuit fails, the system may think a train is still there, blocking others from moving forward.
‘Drivers must stop at red signals and get verbal permission to proceed at a reduced speed, which can cause significant delays, especially in areas with long track sections.
‘In this case, Southern are unable to run services through the area in order to allow Network Rail teams access to the route to rectify the issue.’
Unfortunately the problems don’t end there, with several London Underground lines also facing delays.
The Circle line is fully suspended, and the Hammersmith & City and Mildmay lines are part suspended this morning.
Meanwhile, the Bakerloo, Hammersmith & City and District lines are experiencing severe delays, while the DLR, Central and Elizabeth lines are facing minor delays.
