Siemens and SBB sign long-term framework agreement for the digitalization of Swiss interlockings
Siemens Mobility and Swiss Federal Railways (SBB) are driving
the digitalization of interlockings in Switzerland and have signed a strategic
framework agreement that provides the basis for a more modern and efficient
rail system. With the Signaling X solution, interlocking logic is intelligently
shifted to central data centers, ensuring that rail operations are digitalized from
the ground up. The goal is to increase operational capacity and create a sustainable
and highly efficient mobility infrastructure. The framework agreement covers
the construction of digital interlockings, including hardware and software, as
well as comprehensive services such as development, training, and support. The
agreement has an initial term of ten years and can be extended three times for
periods of five years each. In addition, the partners have agreed to 25 years
of maintenance to ensure smooth and reliable operations. During the project, approximately
500 interlockings will be modernized and around 80 percent of the existing systems
will be replaced over the next 20 years. Commissioning of the first
interlockings is planned for 2029. In the course of the agreement, orders for
the delivery of individual interlockings will be awarded on an ongoing basis.
Michael Peter, CEO Siemens Mobility GmbH: “We are
delighted to be shaping the future of the Swiss railway landscape together with
SBB. At the heart of this transformation are virtual interlocking systems. With
Signaling X, interlocking logic is intelligently shifted to central data
centers, digitalizing rail operations from the ground up. This groundbreaking
technology not only significantly increases the network’s capacity and reliability,
but also decisively contributes to SBB’s climate goals. By providing guaranteed
system availability of up to 100 percent, we are helping to achieve our shared
goal: more trains running at shorter intervals for passenger and freight
transport in Switzerland.”
Siemens Mobility has been firmly anchored in Switzerland for
decades with its entire value chain and is a proven partner of Swiss Federal
Railways (SBB). The company has demonstrated its expertise in a large number of
commissioning projects in the field of control and signaling technology,
including highly complex systems. Experienced local employees cover a project’s
entire lifecycle, including development, project planning, production,
assembly, commissioning, support, obsolescence management, and spare parts
logistics. This comprehensive expertise is a key success factor behind the
long-term partnership with SBB.
Siemens Mobility also has a large installed base at SBB and
has developed a clear evolutionary migration path for these platforms toward
the target architecture. This approach ensures that the existing infrastructure
can be efficiently and sustainably transitioned to SBB’s future objectives. Siemens
Mobility and its predecessor companies have proven over the past 100 years that
they can successfully and reliably fulfill long-term commitments.
The SBB rail network covers 3,266 kilometers, making it the largest
standard-gauge network in Switzerland used for both passenger and freight
transport.
