According to
http://www.tfl.gov.uk/info-for/media/press-
releases/2015/march/new-lifts-for-tufnell-park-station
Tufnell Park London Underground Station has a closure planned from 8th
June, 2015 for 9 months until March 2016.
The closure has yet to be noted on
www.tfl.gov.uk on either the station
service status or the journey planner.
Doubtless, information will be updated nearer the time.

The Customer Service Centre confirmed the closure is planned with the
Station Supervisor, today, Saturday 16th May, 2015.
