I've bought Niederthalbahn and directly notices the PIS displays in Bad Vibel, but sadly not working. My suggestions would be to make them work and also implement them to linke Rhein Strecke since I dislike, that I can't see when the next trains arrive ether at Niederthalbahn nor at Linke Rheinstrecke, that's why I think that this could be a nice addition to those routes
AFAIK they are not part of Mainz-Koblenz because they did't work like they should (and probably likewise with Niddertalbahn). They might be updated, but no promises on that front. It was discussed on stream here: https://www.youtube.com/live/DUBWRKkk6PA?feature=share&t=1175
