Deutsche Bahn begins passenger operations in Berlin’s North-South tunnel. Siemens upgraded the line with the ZBS electronic automatic train control system (Berlin S-Bahn train protection system). The old mechanical train stops have been replaced by eurobalises, which transmit signal data to drivers in the tunnel and can also monitor train speed, a capability previously lacking.
The North-South S-Bahn tunnel is 5.5km long and is one of the most important routes in Berlin’s transportation system. Up to 4,800 trips are made on the North-South line every week.
