Swiss Rail: Siemens-BLS ETCS Level 2 Upgrade Boosts Efficiency

Swiss Railway Modernization: Siemens Mobility to Upgrade BLS Netz AG Network with ETCS Level 2

In a significant stride towards enhanced railway safety and efficiency, Siemens Mobility and Swiss railway infrastructure operator BLS Netz AG have inked a long-term framework agreement worth over EUR 110 million. This agreement will see the modernization of BLS Netz AG’s signalling infrastructure using European Train Control System (ETCS) Level 2 technology. This project, announced recently, aims to significantly upgrade regional lines over the next decade. The “Who” in this case are Siemens Mobility and BLS Netz AG; the “What” is the modernization of signalling infrastructure, including delivery and maintenance; “When” is the coming decade, with initial commissioning in 2029; “Where” will be throughout BLS Netz AG’s 424-kilometre network, starting on the Bern–Schwarzenburg line; “Why” is to boost line capacity and enhance operational efficiency; and “How” is through the deployment of ETCS Level 2 technology and innovative level crossing management. This article will explore the key aspects of this project, its technical details, and its implications for the Swiss railway network.

ETCS Level 2 Implementation: A Technical Overview

The core of this modernization lies in the implementation of ETCS Level 2, a signal-less cab signalling system. Unlike ETCS Level 1, which relies on trackside signals, Level 2 transmits track data directly to the driver’s cab in real-time. This eliminates the need for traditional lineside signals, simplifying the infrastructure and enhancing operational efficiency. The Bern–Schwarzenburg line, a 17-kilometre stretch, will be the first to undergo this transformation. This upgrade will also enable the integration of a new intelligent level crossing management system, which is vital given the numerous level crossings along the route in both urban and rural areas. This system is designed to optimize level crossing closure times, thereby minimizing disruption to road traffic and improving overall traffic flow.

Addressing Infrastructure Challenges: The Bern–Schwarzenburg Line

The Bern–Schwarzenburg line presents unique challenges due to its varied terrain and numerous level crossings. Siemens Mobility will deploy a new intelligent level crossing management system to mitigate the operational hurdles posed by these features. The system’s primary aim is to reduce level crossing closure times, a critical factor in maintaining both railway and road traffic efficiency. This involves optimized control and coordination of level crossing signals based on real-time train movements and anticipated arrival times. Furthermore, the upgrade to ETCS Level 2 will simplify maintenance procedures by reducing the number of interlocking systems required, a key benefit for infrastructure operators. The project aims to ensure a smoother and safer operation of the route.

Enhancing Line Capacity and Future-Proofing the Network

The switch to ETCS Level 2 is a crucial element in enhancing line capacity. By eliminating traditional signal infrastructure, the system allows for closer train spacing, effectively increasing the number of trains that can operate on the line simultaneously. This increased capacity is vital for meeting growing transportation demands and improving service frequency. In addition, the ETCS Level 2 system is designed to be adaptable, setting the stage for future expansions and technological advancements. The modernization prepares the line for potential future expansion. The project aligns with BLS Netz AG’s broader European Rail Traffic Management System (ERTMS) implementation plan, indicating a commitment to adopting standardized, interoperable signalling solutions across its network.

Long-Term Partnership and Network-Wide Rollout

The EUR 110 million framework agreement extends beyond the Bern–Schwarzenburg corridor. BLS plans to progressively roll out similar ETCS Level 2 upgrades across other parts of its 424-kilometre network, as part of its comprehensive ERTMS implementation strategy. This phased approach ensures a smooth transition and allows for the lessons learned from the initial deployment to inform future upgrades. Daniel Pixley, Head of Automation at BLS Netz AG, highlighted Siemens Mobility as the optimal supplier, citing its “convincing complete solution.” This partnership underscores the strategic importance of technology in the future of Swiss railway infrastructure.

Conclusion

The collaboration between Siemens Mobility and BLS Netz AG represents a significant milestone in Swiss railway modernization. The adoption of ETCS Level 2 technology promises to enhance line capacity, improve operational efficiency, and increase safety across the BLS network. The project, beginning with the Bern–Schwarzenburg line, serves as a blueprint for future upgrades and illustrates the potential for intelligent, data-driven railway infrastructure. The implementation of advanced level crossing management systems, coupled with the transition to cab signalling, highlights a commitment to address the unique challenges posed by the railway’s varied geography. The long-term framework agreement with Siemens Mobility underscores a strategic vision to modernize the entire network and ensure it is prepared for future transportation demands. This modernization effort is expected to have a broader positive impact on the Swiss railway industry by setting new standards for performance and reliability of regional lines.
