Launched in December the night Overground service is the sixth line to run the late-night service on weekends.
About 300,000 journeys are being made every weekend on London’s Night Tube service, that was initially launched in August 2016 with great success.
Mayor of London Sadiq Khan said ‘The Night Tube has proven such a success with Londoners, I know the Night Overground will help thousands more who are working through the night or out enjoying our capital’s nightlife’.
