Description of Incident
A fault with the signalling system between London St Pancras International and London Blackfriars, means that some trains are having to run at reduced speed. As a result, trains travelling from London St Pancras International towards London Blackfriars may be delayed by up to 30 minutes or revised.
Disruption is expected until the end of the day.
