Local power failures have meant King's Cross, Regent's Park, Euston and Warren Street stations were shut just as many commuters began to pack up for the day.
Transport for London said local issues had caused the stations on several different Tube lines to be shut shortly after 4pm today.

The two mainline stations - King's Cross and Euston were reopened around half past 4pm, with the power later reset at Warren Street and Regent's Park.
TfL told City A.M. all the stations should be reopened by around 5pm, though Warren Street was still shut at 6.00pm. Regent's Park was announced open again at 5.40pm.
TfL also said the lines themselves (the Bakerloo, Victoria, Circle and Northern) won't have been affected, though there were minor delays on the Northern line from Golders Green to Kennington.
