Some local public transportation "companies" in Germany (which are called "Anstalt des öffentlichen Rechts" - literal translation "entity of public law" - and are more or less non-profit businesses funded by the city) are using OSM data for their apps and websites and they often edit the bus/tram/train routes and stops if they change them. This is where OSM shines: public entities keeping their data up to date for the benefit of all.
