There is now a tool on NRE which you can enter your ticket details into and supposedly it tells you what the permitted routes are. It doesn't work - the results keep drawing a blank. I've tried it in IE, Opera, Firefox and Chrome - all of them come up with the same thing - nothing.
NRE has no working tool which allows the validity of a ticket to be checked. Until such a time that it is fixed, I'm sceptical as to whether the requirement for passengers to check NRE for permitted routes is legally enforceable.
Although this has been a long time coming and it isn't as if we
weren't warned, it does appear that ATOC has rushed something out that is not quite ready for the public to work with. That said, I've gotten to work on the new NRG and it does indeed appear to work with the anomalies that lie within the maps, which should be good to keep those into creative ticketing busy for some time.
