Indeed (although 1 next to 20 always seems a little odd). My point was that in places where they've done this but then altered it, it becomes seemingly random.All platforms at Waverley are numbered logically clockwise. 1, cross to 2, bays 3,4,5,6, 7 through, 8 &9 round the back, turn round on yourself, through 10, cross to 11, bays 12-18, then 19 through, cross to 20. Perfectly logical.
