A signal failure at Stockwell this afternoon has caused chaos across the Northern line, with commuters claiming they have been trapped underground.

At 1.15pm it was reported that a signal failure was impacting trains between Kennington and Morden, causing severe delays on the rest of the line.

However, an hour later the Northern line Twitter account confirmed no service was running between Camden Town and Morden via Bank.

As of 3pm, the line was running again with severe delays.

Angry commuters claiming they have been stuck underground have taken to social media to vent their frustration. 

Tickets are being accepted on London Buses via any reasonable route, and on Southern services between Balham and Victoria.
