A failure of the electricity supply at Selhurst is causing disruption to Southern services this morning.

Commuters are warned that trains may be cancelled and delayed.

It is predicted that disruption will last until 9.00am.

A statement read: "Southern are running as full a services as possible; however, some services will be delayed, cancelled or formed of fewer carriages.

"The electrical issue is only affecting trains coming out of the depot and so Southern are having to move trains around in order to prevent further cancellations."
