Arnsdorf/Kamenz (dpa/sn) – The railway line between Arnsdorf and Kamenz in the Bautzen district is closed due to a technical fault. The fault was triggered by a defective component of the train radio, as Deutsche Bahn announced on Friday. There should be an emergency bus service. The railway is also checking whether trains can run with an alternative train radio system. There is no precise forecast as to when the disruption will be resolved. It should take several days.
