The price model of the rail company doesn't make much sense here (germany). I can travel from Berlin to Paris cheaper, than I can from Frankfurt to Munich for example. But then they have special offers for certain regions sometimes, which you can combine with regular tickets for the rest of your route, which makes it cheaper again. Or in combination with a flight ticket. Or traveling in groups with special ticket, or traveling in a certain region with a specific train and so on. It is so complicated and confusing that even the staff at the train station can't always tell you whats the best ticket.
