Londoners have mixed views about the service...

A YouGov survey revealed last year that 79% of us are happy with the announcement of a night tube service at weekends, one in three have revealed they would never use the service.

Why some are against it:

Confirmation of a 24-hour Tube service at weekends brought music to the ears of many Londoners who have cut short their weekend revelries in order to catch the last tube for the past 153 years.

But the Night Tube - originally set to open in September last year - was delayed because staff were unhappy about the shift and pay changes – despite having been offered a 2% pay rise and a £500 bonus at the time.

The predicted cost of the tube has risen to £17million with subsequent annual costs of £25 million.

Rail worker unions believe that it could bring unfair working hours and pay.

The RMT union maintains that there are still "major" unresolved issues surrounding working conditions - hence the unconfirmed date for all lines opening.

There will also be job cuts due to ticket office closures.

There are concerns among some surrounding the safety of women, and the increased likelihood of drunk people causing disorder or falling onto tracks.
