The long-awaited 24-hour service on the London Underground will be expanded to a third line just weeks of it being launched. The Night Tube is set to begin on 19 August on the Central and Victoria lines following months of dispute and strike action with unions.

The 24-hour tube service now looks set to also include the Jubilee line on 2 September, with the Northern and Piccadilly lines hoping to join in the autumn.

Finn Brennan, district organiser of the train drivers' union Aslef, said: "We welcome the hundreds of new jobs with decent conditions that were created by our action last year. We made sure it was brought in by agreement in a way that benefits existing staff and the new recruits."

A Transport for London spokesperson said: "As the mayor announced last month, London's first ever all-night Tube service will be ready on 19 August on the Central and Victoria lines.

"The start of night Tube services on the Jubilee, Northern and Piccadilly lines will follow in separate phases later in the autumn as new Tube drivers complete their training and final preparations are made. Around 200 part-time drivers are currently taking part in a 14-week training programme to make the night Tube a reality for London."
