According to Deutsche Bahn, the regional train lines RE8, RB10 and RB14 will also run between Südkreuz and Hauptbahnhof via Potsdamer Platz. During the construction work, the Ringbahn will only run every 5/5/10 minutes instead of every 5 minutes throughout. "This means that within 20 minutes, three trains will run in succession at intervals of 5 and 5 and 10 minutes," it said. Among other things, Deutsche Bahn plans to renew the rails and tracks during the construction work. Tunnels and stations will also be cleaned.
