I've been playing around with the National Rail Enquiries journey planner for the sake of seeing what's available after the May timetable change, solely out of curiosity, and not for a specific journey that I want to make. I was looking at journeys from Ely to Brighton, at weekends (or bank holidays). The normal price quoted for this (full price, no railcards) is the £33.20 super-off-peak single, restriction code FB (BRFares link). However if the initial leg from Ely to Cambridge happens to be allocated to a CrossCountry train, the price goes up to the £49.70 off-peak single, restriction code B3 (BRFares link).
This is perhaps most obviously visible if you search for Ely to Brighton journeys on the late May bank holiday, 31st May, between 07:00 and 10:00, when the timetable is such that many of the journeys offered suggest CrossCountry to get to to Cambridge. There are fewer journeys where a CrossCountry leg is suggested at weekends, but the same thing can be seen on the 07:54 departure from Ely on every Saturday.
Can anybody see why the super-off-peak is not being allowed on CrossCountry's trains? I've seen a similar unexpected issue before where a restriction code included a restriction on trains out of Birmingham New Street that was then being applied to any CrossCountry Ely to Cambridge train. But I can't see anything similar this time around in restriction code FB, in either the published or unpublished restrictions. As I said at the beginning, I'm asking out of curiosity, not because I want to actually book the journey.
