Hochbahn, Siemens to upgrade U-Bahn lines

Siemens Mobility says the CBTS system enables an increase in capacity as well as energy savings. 2022, Siemens Mobility

German rail operator Hamburger Hochbahn has partnered with Siemens Mobility to upgrade train control systems for the U2 and U4 lines in Hamburg’s public transport system.

The new system will modernise the conventional train control system currently in use by Hochbahn and will utilise communication-based train control (CBTC) to allow trains to run at shorter intervals of only 100 seconds.

“Siemens and Hamburger Hochbahn have a long history together,” Andre Rodenbeck, CEO for Rail Infrastructure at Siemens Mobility, commented. “Our technology combines greater track capacity, maximum availability, and lower energy requirements with the highest possible level of safety… This project is an important milestone on the road to transforming mobility in Hamburg.”

The partners will install Siemens Mobility’s Trainguard MT CBTC solution to enhance the conventional Sicas ECC interlockings currently in service, as well as adding all necessary technology upgrades to subway cars. Trainguard MT will be available on the U2 line between the Christuskirche and Mümmelmannsberg stations and on the entire U4 line.

The CTBC solution will manage exchange of digital signals and messages in real time to ensure that components along the line and in the vehicles are seamlessly connected. This in turn allows rail vehicles to operate at shorter braking distance intervals than the predefined block section lengths currently required and enables shorter train sequences, increasing transport capacity by more than 20 per cent.

“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,” Henrik Falk, CEO of Hochbahn, commented.
