Actually, "NV" is for "Nahverkehr", which is German for "local services".

I use
bahn.de as a starting point for researching just about any train journey in Europe, as it's easy to use, has good advanced search features (like the one mentioned above) and includes pretty much all trains in Europe. (However, it can sometimes be slightly inaccurate, if for example a train operator has adjusted a service, or failed to provide timetable data around the time of the annual timetable change).
