as of 1 January 2024, DB Netz AG and DB Station&Service AG will merge and renamed to DB InfraGO AG. This requires an update to lots of
operator=* tags including
operator:wikidata=*, and some
owner=* tags. The mechanical edit will also remove existing
operator:wikipedia=* from the modified objects.
The mechanical edit affects mainly Germany, but some infrastructure is located in Switzerland, Belgium and Czech Republic.
You can find the documentation on the wiki.
