Deutsche Bahn was the largest railway company in the world by revenue in 2015;[4] in 2019, DB Passenger transport companies carried around 4.8 billion passengers, and DB logistics companies transported approximately 232 million tons of goods in rail freight transport.[5]

The group is divided into several companies, including DB Fernverkehr (long-distance passenger), DB Regio (local passenger services) and DB Cargo (rail freight).
