London Underground train drivers have voted by almost 9-1 to accept a pay deal for the new all-night tube service.
One of the major unions negotiating the new terms, Aslef, said 88 per cent of its member who voted have backed the new four-year wage offer.
The service was due to start on some lines at weekends last September but was delayed after Transport for London (Tfl) bosses failed to reach an agreement with the unions over pay and conditions.
The dispute led to a series of strikes over the summer.
Aslef officer Finn Brennan said: "Aslef members on London Underground have voted by a huge majority to accept the improved offer on pay and night Tube.
"Last year management tried to force through changes to rosters that would have meant unlimited increases in weekend and night shifts with a pay rise of just 0.5%.
"Our members took two days of absolutely solid strike action to protect their working conditions and win an improved offer.
"Their strength and solidarity have achieved an above-inflation pay rise and real improvements in conditions that will give drivers, and other grades, much more flexibility and control over their work/life balance in the future."
Steve Griffiths, London Underground's chief operating officer, said: "I'm pleased that Aslef members have voted to accept our offer. This is a fair and affordable pay deal, which includes complete protection of employee work/life balance.
"We continue to focus on the recruitment and training of part-time drivers to deliver the night Tube for London as quickly as possible."
Members of the other union involved in the negotiations, the Rail, Maritime and Transport union (RMT) have also voted to accept the offer.
