Stock Photo - 13 September 2023, Mecklenburg-Western Pomerania, Karow: Members of the ""Südbahn"" association stand at the entrance of Deutsche Bahn's ""advanced TrainLab"" test train in the otherwise little-used station of Karow. The citizens' initiative has been calling for years for the preservation and expansion of the Südbahn rail line. The infrastructure manager Regio Infra Nordost had presented the route concept ""Karower Kreuz 365+"" for a more effective use of the rail network in the region at a stopover during the test runs. It is about possible perspectives for an attractive passenger service between the metropolises of Berlin and Rostock on the north-south axis.
