It is interesting to see fare modes of London and most PTEs areas use a pseudo-round-zone fare charging scheme, in which the highest fare zone charges fares and the lowest fare zone travelled, disregarding whether it is a simple High - Low zone journey, or a High - Low - High trip.
Does it mean that operators will make a great loss if a passenger travels from the edge of a PTE area to another edge, and especially if two or more operators are included when changing trains in zone 1 / Central?
