Route X140 which travels between Harrow and Heathrow Central through Northolt has been renumbered SL9 as part of the next stage of the planned Superloop that will be connecting Londoners.
Last month saw the 607 bus, another popular route that travels through Southall, Hanwell, Ealing and Acton from and to Uxbridge and White City renumbered the SL8.
Transport for London (TfL) says the new SL9 service, which went live on 26 August 2023, connects Harrow and Heathrow Central via Northolt running every 12 minutes from Monday to Saturday and every 15 minutes on Sunday.
Buses on the SL9 route will still call at the same stops as the X140, but some of the bus stop names have changed to better reflect their locations, such as Station Parade is now Northolt Park Station.
All SL9 buses are equipped with onboard USB charging for mobile devices which passengers can use.
Deputy Mayor for Transport, Seb Dance said:”It’s great to see more Superloop buses on the streets of London, and I’m excited for the SL9 to join them.”
He added: “The Superloop is delivering more frequent and longer running bus services, with the express services circling the city, providing quicker links between transport hubs, town centres, schools and hospitals and offering Londoners even stronger alternatives to private car use, helping us to build a better, greener London for everyone.”
Louise Cheeseman, director of buses at TfL said: “The newly renumbered and branded SL9 will ensure people in outer London have an instantly recognisable express bus route, helping to make it easier to choose a sustainable way to travel.
“Buses are the most accessible, available and affordable form of public transport connecting outer London’s network to town centres, hospitals, schools and transport hubs. We’ll continue to work on our further plans for the Superloop to make it even easier for people travel around outer London.”
