Hard to work out without station names.
What's the routeing printed on ticket?
Otherwise its a rather convoluted academic exercise that may well not give a definitive answer.
Plus, I've got cricket to watch!

Here is a question to test Routeing Guide experts (or anyone who would like a challenge):
I wish to make a journey from station A to station B. Both of these are routeing points.
The Routeing Guide lists only one valid route between A and B, although two other "reasonable" routes exist.
If there is a ticket from A to B with route "Via C" (where C is common to all three possible routes), how are valid routes from A to B via C determined?
Here are possible options:
a) The "via" could only filter out routes from the list of valid routes, so in this case there would still be one valid listed route (plus the shortest route)
b) Valid routes would be determined separately for A to C and C to B
c) Something else.
Anyone know the answer?
