I kinda wanted to ask about this section "Zugvorbereitungsmeldung (ZVM - Train Preparation Notice) - like, I know this is more sth to do with immersion than sth you have to do in the game, but still... do you do this before starting a service (after registering the data, of course), or do you have to do it at each station? (that section is kinda interesting, so I would like to know)
This just confirms that your train registration is valid (in Germany only) so you just need to do it once when starting a service.
