A signalling fault at London Liverpool Street which twice broke out today, causing delays for morning commuters and mid-morning passengers, has been fixed.

Delays of up to 30 minutes were reported throughout the morning rush-hour after the fault was initially reported at around 7.20am.

The signalling problem affected services in and out of platforms 11, 12 and 13 at London Liverpool Street until around 8am when Network Rail engineers had appeared to resolve the fault, prompting all lines to re-open.

However, a reoccurrence of the signal fault was reported at around 11.10am, blocking access to platforms 11 and 12 at London Liverpool Street.

But the latest signal problem appears to have now been fully resolved.

The Greater Anglia Twitter account posted at around 12.50pm: “#LiverpoolSt -Disruption caused by a fault with the signalling system has now ended. Apologies to all passengers affected by delays.”

Earlier, the 8.48am Ipswich to London Liverpool Street and 8.20am Ipswich to Cambridge services were cancelled.

Services that were delayed during both periods of disruption terminated at Stratford and Shenfield stations.
