Swiss Federal Railways Awards Over One Billion Framework Contracts for Digital Interlocking Systems to Hitachi, Siemens and Stadler: New Update

Swiss Federal Railways (SBB) has taken a major step forward in modernising its rail infrastructure by awarding framework contracts valued at CHF 1.4 billion (around $1.8 billion USD) to Hitachi, Siemens, and Stadler Rail. These contracts, which focus on the supply and ongoing maintenance of digital interlocking systems, are set to last 10 years, with the possibility of extending them for an additional 15 years in total. This deal marks a critical milestone in SBB’s efforts to upgrade its signalling systems and boost the efficiency of the Swiss rail network.

Revamping Switzerland’s Rail Signalling Systems

SBB’s current rail network relies on nearly 500 interlocking systems, many of which are based on 1950s technology. These outdated systems use relays and are increasingly difficult and costly to maintain. Moreover, the technology’s limitations have hindered further expansion, particularly in terms of installing new switches and improving the overall functionality of the network. The need for a comprehensive upgrade is urgent, especially as Switzerland’s rail infrastructure becomes more complex and the demand for efficient, reliable services increases.

To address these challenges, SBB is embracing digital interlocking systems, which will replace the old technology with modern, more efficient solutions. The digital systems will standardise components, making them modular and easier to maintain. They are also more adaptable, allowing for future upgrades and integration with cab signalling technology, which will significantly enhance rail network capacity and safety.

Contract Details and Award Process

The framework contracts were issued in two lots in autumn 2022. Lot 1 covers the complete systems, including both the hardware and software required for digital interlockings, while Lot 2 focuses on object controllers. These are electronic components used to operate switches, signals, and monitor track sections. In the competitive tender process, Hitachi and Siemens secured the contract for Lot 1, while Stadler Rail was awarded Lot 2.

This contract structure allows SBB to award individual interlocking system contracts throughout the phased modernisation process. While Hitachi, Siemens, and Stadler are now officially part of the framework, they will still need to compete for specific contracts under future tenders. SBB will select the most advantageous offer based on the needs of each specific project, ensuring flexibility and competitiveness throughout the upgrade.

The Importance of Digital Interlocking for Swiss Rail

Digital interlocking systems are essential for improving the capacity and safety of rail networks. By transitioning from older, relay-based systems to modern digital solutions, SBB can improve the management of rail traffic, allowing for more frequent and efficient train services. Cab signalling, which will be implemented in conjunction with these digital systems, will enable trains to run at shorter intervals, further increasing the network’s capacity.

Additionally, the modular nature of the new digital interlocking systems means that individual components can be easily replaced and upgraded as needed, which will reduce long-term operational costs and make the systems more sustainable. The ability to modernise and adapt to future needs is a significant advantage of the new technology.

Timeline and Future Outlook

The first digital interlocking system is expected to be commissioned in 2029, marking the beginning of a 40-year modernisation programme. Over the next 20 years, SBB plans to replace 80% of its existing interlocking systems. The selection of systems for replacement will be based on various factors, such as the end of their operational life, the benefits of the upgrades, and the rollout of cab signalling technology.

The digitalisation of Switzerland’s rail signalling will not only enhance the efficiency and safety of the network but also help meet the future demands of both freight and passenger rail services. SBB’s move towards modernisation reflects a broader trend in the rail industry, as operators around the world embrace digital solutions to improve performance, reduce costs, and support the transition to more sustainable transport systems.
