All operators run on DB infrastructure.

Rails, buildings and train stations are in separate company (DB InfraGO), owned by DB.

But DB has no monopoly on trains in Germany, any company can run trains there.

A nice thing about the Deutsche Bahn is that they exist. It's not the case in every country in the world.

EU does not have a train monopoly. There are other train companies in Germany (FlixTrain, OBB, BRB...). And operators from other countries can also operate there, even French SNCF!

DB is blocking slots on rail, that could be used by other operators. And they are not going to change because it is Germany.
