How do we determine what the permitted route for a route X specific ticket is if no mapped routes pass through X? Is it simply the shortest route passing through that point?
Do you know if they said anything about "journeys from X to Y may go via Z" easements? It would be nice to know what they should mean, rather than just which routes a particular ticket site will sell tickets for.I believe someone managed to obtain some clarification from ATOC regarding this issue, who explained that in such case, the ticket holder is permitted to travel from the origin to station X using any permitted route between the origin and station X, then from station X to the destination using any permitted route between them.
I am unable to find the documentation for now.
ATOC said:Thank you for your enquiry. My apologies for the lateness of reply but we have been waiting for clarification from industry colleagues.
The Routeing Guide lists the permitted routes for a particular flow. The actual routes that the customer can use, is sometimes limited by the route shown on the ticket, which may stipulate that the journey must go via a particular location. In some cases however, the opposite applies and the particular “via” location is outside the range of the usual permitted routes and travel via that location would not normally have been permitted. But because a flow specifically routed via that location has been priced by the Train Company , travel is permitted via that location. It appears that this is the case for Sheffield – Blackburn, via Burnley.
In this instance you are correct and you should look up the permitted routes for Sheffield-Burnley and Burnley-Blackburn.
