Transport For London (TfL) is set to launch new round-the-clock underground train service Night Tube in London.

Trains will run on the Central and Victoria lines every 30 minutes on Friday and Saturday nights and every 20 minutes on other weekdays.

TfL has also announced eight new 24-hour bus services to support the Night Tube.

London's Mayor Sadiq Khan said: “The Night Tube is going to transform our city as for the first time tube passengers will be able to travel swiftly across the Capital throughout the night.

"In recent years, the number of night bus services has increased and the numbers of passenger have doubled since 2000."

“The safety and security of Londoners is vital, and it's why we've invested in new police officers on the Tube and it's why we're bringing in these brand new 24-hour bus services. The routes will go hand-in-hand with the Night Tube to help Londoners get to and from their front door throughout the night.

“It's another key step in helping everyone travel quickly and safely at night, and another boost to unlocking the full potential of our night time economy.”

TfL noted in recent years, the number of night bus services has increased and the numbers of passenger have also doubled since 2000. TfL currently has a network of around 700 bus routes across Greater London, with almost 2.4 billion passengers every year.

The plan for Night Tube was first announced in November 2013 with an aim to start the service in September last year. However, strikes over reimbursement delayed the service, reported BBC.
