Major delays into Waterloo and Victoria

Rail commuters using two of London's busiest operators - South West Trains and Southern - suffered major disruption due to signal failure at Dorking.

Trains into mainline Waterloo and Victoria stations suffered delays of up to 45 minutes.

The problem disrupted SWT services from Dorking via Epsom to Waterloo and Southern trains from Horsham via Leatherhead and Victoria.

Through-London First Capital Connect (Thameslink) trains were delayed due to Network Rail safety checks being made on the track in the Wimbledon area.

This also caused delays to Southern services into London Bridge.

A broken down train at Brentwood caused delays of 20 minutes for Greater Anglia services using Liverpool Street station.
