Siemens to Install CBTC Signalling on Hamburg’s U2 and U4 Lines

Siemens Mobility has been contracted to supply and install its digital Trainguard MT CBTC solution on lines U2 and U4 of the Hamburg subway, operated by Hamburger Hochbahn.

The CBTC technology will allow trains to run at shorter intervals of only 100 seconds. This will enable more trains to operate in order to increase the network’s capacity.

In addition, CBTC also improves punctuality, reliability and energy efficiency by up to 20 percent.

CBTC HamburgTrainguard MT will be available on the U2 line between the Christuskirche and Mümmelmannsberg stations and on the entire U4 line

Henrik Falk, CEO of HOCHBAHN, said:

“For the mobility transition, we need powerful and reliable systems that create real customer benefits. Through the U-Bahn100 project, we’re creating a service for our passengers that is simply unbeatable: a subway train every 100 seconds – on time, reliable, environmentally friendly, and effectively available at all times.”

Communication-based train control (CBTC) is a system of digital signals exchanged between the track and the subway vehicles.

This allows rail vehicles to operate at braking distance intervals rather than with predefined block section lengths.

Once shorter headways are implemented, the network’s capacity can increase by more than 20 percent without expensive and timely construction projects.

Andre Rodenbeck, CEO for Rail Infrastructure at Siemens Mobility said:

“This project is an important milestone on the road to transforming mobility in Hamburg. In the future, trains on the U2 and U4 lines will be able to run every 100 seconds. Siemens and Hamburger Hochbahn have a long history together, and we’re extremely proud to be able to implement our innovation here in Hamburg. Our technology combines greater track capacity, maximum availability, and lower energy requirements with the highest possible level of safety.”
