Commuters travelling to Liverpool Street are facing severe delays due to a broken rail in east London.
Routes between the busy station and Stansted Airport, Cambridge and Hertford East have been hit by cancellations and delays, with disruption expected to continue until the end of the day.
National Rail has warned that the broken rail was found overnight and the extent of the damage meant that the repair work could not be completed in time for the start of service on Tuesday.
The issue has hit Greater Anglia, London Overground and Stansted Express services.
No trains are able to run between Hackney Downs and Chingford on the London Overground. The issue has also sparked severe delays between Liverpool Street / Cheshunt and Enfield Town on the line.
Elsewhere on Tuesday morning, there were severe delays between Paddington and Heathrow Terminals / Reading while Network Rail fix a points failure at Southall.
