they have driven off in to the bus afterlife..well been sold on to their next incarnation is probably more accurate.
Replaced by smaller buses named after that less easily described colour from the rainbow, the buses themselves are a sort of pinky purple.
Smelling of "new" they have leather seats and a floor suggestive of wooden laminate. They have blue LED light just above floor level on the outer seats. not so happy about those they make my eyes ache.
I miss the yellow bus it was easier to see, some of my fellow passengers (pre advertising of the change not withstanding) have missed the new ones in surprise at the change of colour and shape of the bus.
I think I would have preferred they keep the old colour.
