There are delays on the Elizabeth line this morning after a signal failure in east London.
The signal fault, at Gidea Park station, is forcing trains towards Romford to run at a reduced speed, causing delays and potentially cancellations.
The issue is affecting Elizabeth line services between Shenfield and London Liverpool Street, London Paddington, or Heathrow Terminal 5.
There are minor delays between Shenfield and Whitechapel at the moment, with good service on the rest of the line.
It’s also impacting Greater Anglia services between Liverpool Street and Ipswich, Norwich, Clacton-on-Sea, Colchester Town, Southend Victoria, Southminster, or Braintree.
Network Rail staff are already on site to try and fix the problem.
Meanwhile there are minor delays on the Hammersmith & City and Metropolitan lines on the London Underground this morning, caused by train cancellations.
