Part of the London Overground is suspended due to a power failure and passengers have been evacuated.

There is no service between Highbury and Islington and New Cross/ Clapham Junction/ Crystal Palace/ West Croydon due to a power failure in the Surrey Quays area.

Passengers took to Twitter to vent their frustration after being stuck on trains for more than an hour before being evacuated.

@LDNOverground you've had over an hour. Sort it out or let us get off!

Tickets are being accepted on the London Underground.
