Geograph - photograph every grid square

The map on the side of the bus shows the route Uxbridge - Hayes - Ealing Hospital - Ealing Broadway - White City.
This is a radial route of the Superloop. At Hayes it crosses an existing route round the loop, SL9 from Heathrow to Harrow. Other routes are being added.
The Evening Standard in July 2023 Link reported:
"Buses on the limited-stop 607 between Uxbridge and White City will be rebranded – in the Superloop “retro” colours and roundel – as SL8.

Three other existing routes - the X140 and the X26 that both serve Heathrow and the X68, which links Croydon and Russell Square – will be also be renumbered and rebranded as Superloop routes this summer."
A bus on the 607 route replaced by SL8 is shown in TQ1380 : 607 bus in the Uxbridge Road.
