Setting aside the matter of what route costs more/what costs less for a minute, (as these are constantly subject to change and except for associating stations with RP, price does not determine validity), focussing purely on the reasonableness of the route itself, and not delving into Liverpool-Manc-London as that has been addressed in another thread; can anybody advise if any of these routes were valid at privatisation? Alternatively if anyone can remember them definitely being valid at some point, that too would be helpful.
Crewe to Liverpool via Warrington is reasonable, but not permitted at time of writing.
Manchester to Wrexham via Liverpool is reasonable, especially true since the introduction of 30m non-stop TPEs from Manchester to Liverpool, which can allow quicker journeys than via Crewe. Not permitted.
Liverpool to Salford Crescent via Wigan is reasonable, but seems to fluctuate between valid/not valid depending on journey planner used, and is not valid in the NRG. Liverpool to Manchester via Wigan is slightly more debatable but not too unreasonable.
Newcastle to Manchester via Sheffield (and Chinley) isn't too much of a detour but I'm 50/50 on whether this should be valid or not because it adds +30m to journey time.
Any thoughts/further examples?
