Sorry, please read my answers correctly: I never said my source will be the only correct one. But it is the only proof we have to this puzzle in the moment. I severly trust in your exorbitant bus knowledge, but only another proof can convincingly confirm the result of the puzzle. No need to be offended, but I'm only interested in confirmed results. Even if one source may be wrong, not just guesswork. That's the only reason, why I am playing this game. Not for even pointless points, as I have often proclaimed before..
