Farringdon Station has been evacuated this evening after a fire alarm prompted a full-scale response, causing major disruption to commuters during peak travel hours.
Passengers were ordered to leave the station at around 6:20pm, with large crowds quickly gathering outside as services on both the Elizabeth line and Thameslink were suspended.
In a service update issued at 6:30pm, National Rail confirmed that trains travelling through the area may be cancelled, delayed by up to 20 minutes, or revised to skip Farringdon station entirely.
Initially, disruption was expected to last until 7:15pm, but National Rail later announced that no trains will stop at Farringdon for the remainder of the day.
Images from the scene show crowds of frustrated commuters waiting outside the station entrance, many of whom are believed to be workers heading home after their day in central London.
No further details have been provided about the cause of the fire alarm or whether an actual fire occurred, but safety protocols require a full evacuation while checks are carried out.
Transport authorities have urged passengers to check live updates before continuing their journeys and to allow extra time for travel.
Further updates will be provided as more information becomes available.
