Large sections of track on the Tube will be closed for weeks for repairs, London Underground (LU) has said.
Large sections of track could be closed for weeks at a time
Carrying out work over several weeks, rather than overnight or at weekends, would be more cost-effective, says Transport for London (TfL).
It said it was unlikely any large scale closures would take place this year.
London's transport commissioner, Bob Kiley, described carrying out work in the middle of the night as like "death through a thousand cuts."
Mr Kiley said he expected the plan to be met with some opposition at first but was confident passengers would understand.
"If you can deliver a really different and better product at the end, they will appreciate it," he said.
"It's death through a thousand cuts with you trying to do things in the middle of the night. On weekends it's not a great place to be."
The plan is being broadly supported by London Transport Users Committee.
"Big bang closures are more popular with passengers than work being done in dribs and drabs as long as it is properly planned and communicated," a spokeswoman said.
Metronet, which is responsible for upgrading and maintaining most of the Tube network, said it was in talks with LU about the plan.
