VBN: swiss nightjets not categorized as such

Search for Hannover - Bremen at 5:51 AM using just "fast rail"

It is in fact a train by SBB and they sell it as Nightjet or Intercity:

(Sidenote: I don't know if 20N is correct. bahn.expert has it as NJ 470 / IC 60470, which are the numbers found on sbb.ch)

20N is a route name, NJ 470 is the trip name. We have scripts to show the trip name were that is more relevant. Maybe this is just an oversight, but sometimes the data only contains the number, missing the category. If the route type is also generic, it's not really possible to reconstruct "NJ 470" from the data.

EDIT: In this particular case, we should probably just remove SBB stuff from VBN if possible, that would already be coming from two other sources.
