Transport for London Confirms Night Tube Introduction Delay

Plans to introduce all-night service on several London Underground lines have been delayed to allow for conclusion of talks with labor unions, Transport for London said.

The London Underground operator said this would allow for more time to reach a deal on pay and conditions for staff.

No new date for a start of the service has been announced. The subway operator said it wanted to reach an agreement for a start in the fall.

Union members previously staged two 24-hour strikes during a lengthy negotiation period. The strikes brought chaos to London's transportation system.

London Mayor Boris Johnson has so far resisted demands made by union leaders.

London Underground Managing Director Nick Brown said: "Further to the progress made in recent days with the trade unions and the suspension of strike action, we believe we are not far from an agreement that protects the work-life balance of our employees and is affordable, sustainable and fair.

"As such, we have decided to defer the introduction of the night Tube to allow more time for those talks to conclude. Our objective is to reach an agreement that ends this dispute and delivers the night Tube for Londoners this autumn."
