Rail disruption is affecting London-bound trains this afternoon, with National rail warning passengers to expect potential delays and cancellations till the end of the day.

Southern, Gatwick and Thameslink trains are named amongst the affected. This is due to rail safety inspections which took place earlier today.

Thameslink says that journeys between East Croydon and London Bridge may take up to 20 minutes longer than usual due to a signalling fault.

Due to the signal failure, trains heading North to London Bridge (via Tulse Hill) will start from Selhurst instead of East Croydon or could be cancelled.

Tickets are being accepted on alternative routes and services, including London buses, Underground stations and trams.

Rail operators are advising passengers to allow extra time for journeys and use the live map of the network when planning travel routes.
