This is an oddity. I have no doubt that there are people here that watch "Top Gear". You will recall that there are at least 2 laps of the Top Gear track - one by 'A Star in a Reasonably Priced Car' and another lap by The Stig in some sort of performance car. On nearly every lap, early on, there is a red double-decker bus in the background. At first, I thought it was a Routemaster, but in a recent programme, the camera lingered long enough for me to get a better look. It looks like an Alexander J-type bodied Atlantean or Fleetline. There are a few questions that this raises -
1) Is this bus part of the Top Gear inventory - if so, what do they want with it?
2) Is there another firm on the Top Gear site that uses buses?
3) Does anyone know what this bus is? It's quite possible that there is >1 bus.
For the uninitiated, the Top Gear test track is on Dunsfold Airfield, about 3 miles southwest of the village of Cranleigh in Surrey. Alternatively, it's about 7 miles southeast of Godalming. If you use Google Maps, you can see the test track markings of The Hammerhead or Chicago.
I sent an e-mail to the editor of Top Gear about 2 weeks ago, but I haven't had an answer. I reckon my e-mail was intercepted by Hammond, who has a pathalogical hatred of buses!
