Transport for London’s official Victoria Line Twitter account tweeted: “Please be aware that Euston station is closed due to a fire alert.
“Please use alternative stations or allow some extra time for your journey.”
A TfL spokeswoman told Daily Star Online that the issue was believed to be an issue with an underground train and not a fire.
BBC reporter Helen Grady tweeted: “Euston station evacuated just after a ‘not in service’ Northern line train seemed to spew out smoke that made it hard to breathe.”

Another user added: “I will happily leave Euston immediately.”
Further down the line, Kings Cross station has also been evacuted.
British Transport Police urged passengers not to panic and said the situation would be over soon.
In a statement it tweeted: “
We’ve been called to Kings Cross and Euston London Underground stations following a fire alert.
“It looks like the alert was caused by a faulty train. No cause for concern and we’re working with @TFL to open both stations as soon as possible.”
