Q. Does Halifax pass the "fare-check" test to be a Routeing point for Accrington-London?
Yes, it only applies when the passenger is actually on this train.Q. Where the Direct Train rule IS appropriate, does it apply only if the passenger is actually on the direct train?
No, an easement overrides the Permitted Routes found in section (a) of your discussion of the Routeing Guide. So a positive easement allows an additional route to be valid (which would not otherwise have been so) while a negative easement forbids a route which would otherwise have been permitted.Q. Does a favourable easement cause a route to become 'Permitted' or is this wred best left for routes that are Permitted BEFORE we look at easements.
It only applies to trains covering the whole journey. As soon as you start looking at routeing points only mapped routes count (not direct trains or shortest routes).Q. Does the fact that there is a direct train from a valid Routeing point (Halifax) to the destination (London) automatically make this train's route permitted. Or does the "direct train" rule only apply to trains covering the whole journey?
Yes.Q. If the route is Permitted, but not by reason of shortness or directness, is it because the route can be traced out on a valid set of maps?
