The Night Tube is expected to launch in March

The Night Tube launch is now delayed until March.

Originally meant to open this month, it was recently announced that it was to be pushed back, with City A.M now reporting it might not open until spring amid problems between Transport for London (TfL) and transport unions.

A source involved with the negotiations said: "Senior managers have been told by their operations team to work towards March. TfL has said they are committed to the autumn but it's possible they don't have a date in mind at all."

However, Steve Griffiths of London Underground hopes it will arrive before the end of autumn, saying the organisation hopes to "reach an agreement that is affordable, sustainable and fair".

With negotiations between TFL and the unions set to continue next week, Finn Brennan, the district organiser of trade union Aslef, is pleased with the delay.

"This is a significant victory for staff on London Underground and this trade union. We have prevented new rosters being imposed and stopped the attempt to destroy [Tube drivers'] work life balance."

Good for him, 'cause we sure aren't too happy.
