I haven’t noticed it so much recently, but Edinburgh used to have quite a

Stagecoach do that a lot (at least in some areas). At weekends it's common
to see buses on the wrong routes.

Back when it was still all London Transport, did red buses ever appear
on green (country) routes or vice versa, where the two systems
overlapped?
