DIGITAL OPERATIONS CONTROL SYSTEM MAKES TRAINS MORE ENERGY-EFFICIENT
Siemens Mobility, Deutsche Bahn, and the city of Hamburg have signed a cooperation agreement for Digitale S-Bahn Hamburg 2.0.
Digitale S-Bahn Hamburg 2.0
With the Digitale S-Bahn Hamburg, train travel will become even more environmentally friendly in the future. Siemens Mobility, Deutsche Bahn (DB), and the city of Hamburg are introducing a new intelligent operations control system for the Digitale S-Bahn in Hamburg, aiming to reduce the trains' power consumption by up to 30 percent. The system will be tested until the UITP World Congress 2025. The project, costing 35 million euros, is jointly funded by DB, the city of Hamburg, and Siemens Mobility. A cooperation agreement for the Digitale S-Bahn Hamburg 2.0 was signed by representatives of the partners.
The intelligent operations system of the Digitale S-Bahn Hamburg 2.0 saves energy through two approaches. With the technology knowing the exact positions of all trains in the network, rolling phases can be better utilized, and stops on the track can be avoided. Furthermore, the system reduces peak loads in power consumption by preventing multiple trains from starting simultaneously on the track. The project will also include a study to investigate the potential of energy recuperation through inverters in the public power grid.
The technology of the Digitale S-Bahn Hamburg is already in daily use for passengers. Four digitally controlled trains are currently operating on the Hamburg route between Berliner Tor and Bergedorf. 64 new S-Bahn trains equipped with digital technology have already been ordered. By the end of the decade, the city area of the S-Bahn Hamburg is planned to be equipped with the digital system. In 2021, the partners of the Digitale S-Bahn Hamburg jointly introduced the world's first highly automated train in an open railway system.
