Aylesbury - London Terminals Any Permitted

[Metrailway]

From ATOC's Routeing Guide (Section A):

Common Routeing Points
If the origin and destination have a common routeing point, the permitted route is direct via the shortest distance from the origin to the destination over which a regular scheduled passenger train service operates. No doubling back (passing through the same station twice on a single journey) is allowed which may require customers to change trains short of the routeing point, unless an easement allows a longer alternative route.

Does this mean that an Aylesbury - London Terminals Any Permitted ticket is invalid if one takes the shuttle to Princes Risborough and changes there for a train to London?

This was permitted by Easement 54, which appears to have been removed at the last revision.

Unfortunately you can no longer go via Princes Risborough unless using direct trains.

Disappointing - Anyone know why they removed the easement?

However, NRE is still offering the same fare for a change at Risborough journey.

Some people argue that if you purchase a ticket according to an itinerary then that itinerary will have to be honoured. I'll let you decide what your interpretation is.

FWIW fares from Princes Risborough are no more expensive and valid via Aylesbury so if you go out one way and come back the other, it can be useful.

Whilst a strict interpretation of the routeing guide says you can't go via Princes Risborough to Aylesbury most of the time (as it's neither the shortest route, nor within three miles of same, nor a through train, nor a mapped route), I can guarantee that the Any Permitted tickets (at least to/from London Terminals) exist explicitly to allow you to travel that way and nobody would say you were off route, whereas they would if you were trying to use a ticket routed via Chalfont & Latimer that way.
