Sadiq Khan to launch London's night tube service
Mayor to ride first train on overnight service promised by his predecessor Boris Johnson almost two years ago
The mayor of London is to ride the first night tube on Friday evening when the much-delayed project finally goes into service.
Trains will operate through the night on Fridays and Saturdays on the Victoria line and parts of the Central line, with the Jubilee, Northern and Piccadilly lines following in the autumn.
