Bus route X26, connecting communities between Heathrow Central and West Croydon, will be now be known as the SL7, becoming the third route to join the Superloop network.
The Superloop network is a major expansion of outer London’s bus network, circling London and connecting town centres, hospitals, schools and transport hubs.
Route X26 between Heathrow Central and West Croydon became renumbered to SL7 on Saturday 19 August, offering an express bus service between west and south London.
In March, the London mayor Sadiq Khan announced plans for the Superloop, an expanded network of express bus services in outer London in the hopes of improving public transport options and maximising the benefits of the London-wide ULEZ expansion.
The SL7 will double in frequency to one bus every 15 minutes instead of every 30 minutes, providing more frequent public transport options for those travelling to and from Heathrow Airport.
Other improvements to follow on many of the buses include improved customer information, USB charging and luggage racks.
Khan said: ”The Superloop will be a gamechanger for travel around outer London, delivering quicker links between transport hubs, town centres, schools and hospitals.”
Supported by funding from the mayor, the Superloop is a key part of his commitment to improve the bus network in outer London and could add more than four million additional kilometres to London’s bus network.
The first Superloop buses were launched in July, and these services are intended to provide Londoners with stronger alternatives to private car use and help to build a better, greener London for everyone, according to Khan.
