Victoria station was evacuated during this morning’s rush hour after reports of smoke coming from Boots chemist.
The National Rail station was closed for about half an hour from 8am as fire crews attended the scene. The underground station remained open but big queues formed outside.
Trains were held just outside the station with hundreds of commuters as the alarm was sounded and a Network Rail spokesman said: “We understand the alarm sounded after there was a fault in a chiller cabinet at Boots at Victoria.”
London Fire Brigade tweeted at 9.57am: "No fire, just a false alarm. We're leaving the scene."
Transport for London’s Twitter account said: “Victoria National Rail station has closed due to a fire alert.”
Delays are still expected due to a back-up of services.
Commuters travelling in from west London have also experienced severe delays due to closures on the District line between Ealing Broadway and Turnham Green because of a signal failure at Acton Town and also between Upminster and Richmond and minor delays between Edgware Road and Wimbledon.
On the Piccadilly line there was no service between Uxbridge and Acton Town because of the same failure, and also no service between Uxbridge/Northfields and Hammersmith and severe delays between Hammersmith and Cockfosters.
These closures and delays were still ongoing at 10am.
