Hello and thanks for getting back on this topic!

I do not know if you have planned any more changes like this, but unfortunately this is not a good idea. In case yes, please get in touch with the German community beforehand.

Some background information: this stop is served by bus 715, which is operated by the company Allerbus. Each of the (many) companies that perform PT in Germany is responsible for providing printed schedules for their stops. This is what you get when you generate a PDF from the selection of line 715 on the link you provided. The stop names in these do differ widely from the official ones (due to technical restrictions in different systems most of the time). You will notice the difference when using https://www.vbn.de/fahrplaner instead and type "Brunsbrock" as start or destination.

The ONLY official source for PT stop names in Germany is the "Zentrales Haltestellenverzeichnis" which is a curated directory of stops that contains ~239.000 of them.

Apart from the above, PT mapping in OSM is a complex thing that involves relations and should not be done with an "iD" based editor as this is prone to breaking things. Also you need proper training on how to do things right (e.g. in this case you changed the stop but omitted the stop relation).

Please don't take it personal, but I will revert this change. Thanks for your understanding. Have a good day!
