I wonder if its because NWR only get a priv discount with certain TOCs, and its to prevent ticket office or on train staff just issuing them to whereverOut of interest, I see RDG have offered Network Rail the Priv with this weird limitation - does anyone know the reason why it's online only? I understand the discussion around the differences between the TOCs and NR and everything, but if RDG agrees to the idea that NR staff could have access, it just seems a bit petty to put extra restrictions on.
