Blue skies ahead for sky blue routes

1 month ago Wed 27th May 2026

We’re excited to announce that we’ve introduced newer, low-emission gas buses onto both sky blue 15 and sky blue 16 this May. 

You may be familiar with these gas buses as they were previously our low emission, purple 17 buses; however, they have now been fully refurbished and given a striking new sky blue livery.

Offering free wifi onboard and USB charging at every seat, the buses also feature a glazed staircase and a sunroof to allow extra light in as well as a table seat and reupholstered seating too. 

The buses also offer a quieter, more comfortable ride as well as front and rear doors to help speed up boarding.

Replacing our previous diesel-powered sky blue buses, these refurbished buses are part of our compressed natural gas (CNG) fleet and produce up to 84% less CO2 emissions compared to the previous diesel buses. You can find out more about our CNG buses here.

With the introduction of these buses to on our sky blue routes, all of our bus routes along the busy Oxford Road corridor will now be ultra-low or zero emission, helping improve the local air quality. 

We hope you enjoy the upgraded buses on sky blue 15 and 16.
