Southern has confirmed that this mornings fault between East Croydon and Gatwick Airport will cause disruptions until the end of the day.

A statement reads: "Trains across the whole Gatwick Express, Southern and Thameslink networks may be cancelled, delayed by up to 60 minutes or revised."

Commuters are advised to check train times before travelling this evening.

Southern Metro services are the worst affected and commuters are asked to use alternative routes if possible.

An electrical power supply issue between East Croydon and Gatwick this morning initiated the day of delays and cancellations.
