Tube Repair Work Over 18 Months
Passengers on the Jubilee Line are facing more than 18 months of periodic part-closures due to maintenance work.
Acid water is eating into the tunnel walls and causing damage.
The work includes six-day closures between Finchley Road and Waterloo stations during Christmas 2013 and Christmas 2014.
There will also be a closure of this section over Easter 2014.
The work covers a number of weekends and bank holiday periods from June this year to the end of 2014, with the possibility of some additional closures in 2015 in order to complete the maintenance.
London Underground's Jubilee, Northern and Piccadilly lines' programme director Stuart Harvey said today: "All railways require a programme of maintenance and we will soon be carrying out work on the tunnel lining on a section of the Jubilee line.
"This is part of ongoing maintenance and, due to the nature of the work, some closures during weekends will unfortunately be required between Finchley Road and Waterloo."
He went on: " We will be doing as much of the work as possible overnight; however, in some cases we need to carry on beyond normal overnight engineering hours and normal weekend services will not be able to operate.
"I apologise to customers for the disruption. We'll be keeping the impact to a minimum by spreading the work out and including some later-starting services on Sunday mornings to minimise the overall number of closures."
