When the X-Lines livery was first revealed I thought it was a little odd that the gold was towards the front, and the colour unique to the route was at the back. I would have thought the colour unique to the route would be at the front, so as the bus approaches from a distance you have an idea if its the one you're after. Similarly if theres a line of buses on stand at a bus station, surely the unique colour at the front would be more useful than just being able to see a line of gold buses, right?
And if we're being picky, how come the ToonTour's 2 sloping corporate lines point backwards like the X-Lines livery, rather than point forwards like the corporate & non X-Lines liveries? ;-)
