Deutsche Bahn (German Rail) is the major German railway infrastructure and service operator. Though Deutsche Bahn is a private company, the government still holds all shares and therefore Deutsche Bahn can still be called a state-owned company. Since its reformation under private law in 1994, Deutsche Bahn AG (DB AG) no longer publishes details of the tracks it owns; in addition to the DBAG system there are about 280 privately or locally owned railway companies which own an approximate 3,000 km to 4,000 km of the total tracks and use DB tracks in open access.
