The Piccadilly line will run a significantly reduced train service from tonight due to strike action.
The Rail Maritime and Transport union (RMT) and the Transport Salaried Staffs Association (TSSA) will begin their strike at 9.30pm and will conclude on the morning of Friday, February 7.
This will mean trains will run approximately every ten minutes between Arnos Grove and Cockfosters stations, both in Enfield.
Trains will not run through Southgate Station in Enfield.
Strikes have been triggered by plans to close all ticket offices, which unions say will result in job losses.
London Underground managing director Mike Brown, said: “Our customers and staff are at the very centre of our plans for London Underground. All Tube stations will remain staffed and controlled at all times when services are operating, and we’ll be introducing a 24-hour service at weekends during 2015. In future, there will be more staff in ticket halls and on platforms to help customers buy the right ticket, plan their journeys and to keep them safe and secure.
“We’re committed to implement these changes without compulsory redundancies and there’ll be a job for everyone at LU who wants to work for us and be flexible.
“My message to the unions' leaderships is that it's not too late to do the right thing, call off this completely unnecessary strike and work with us to help shape the future of the Tube. All a strike will achieve is to lose those who take part four days’ pay. Should the strike go ahead, we’ll do all we can to keep customers informed and ensure we keep London moving and open for business.”
