London Underground is to hire an army of part-time drivers in a bid to rescue its troubled plans for the Night Tube.
LU bosses say drivers will no longer be forced to work on the new service but the offer of a £200 bonus per shift has been withdrawn.
Plans for all-night trains on Fridays and Saturdays stalled months ago in a bitter row over pay and rosters.
LU was forced to abandon the proposed launch on September 12th, timed to coincide with the Rugby World Cup.
The Night Tube is one of Mayor Boris Johnson's flagship projects but the wrangling threatened to delay it's start until after he leaves City Hall in May.
Managers urged the tube unions to allow staff to vote on the new proposal which also includes a revised four-year pay deal.
