  • The introduction of reasonableness criteria into signalling and safety technology | December 2024

    DB InfraGO AG and the Control and Safety Technology Division will implement Digitale Schiene Deutschland projects until 2035 et seq. Digital, standardisedand high-performance products are being developed in accordance with the Operational Technical Target Image and implemented in projects. Furthermore, processes are being standardised and costs reduced over the entire lifecycle. Rules, specifications and products are being developed with new methods (e.g. “Scrum”) and project rollouts are being parallelised in order to accelerate the project implementation.

    A testing strategy to limit field tests in the development of fully automated driving | November 2024

    This article describes the major challenges pertaining to testing fully automated trains that will be addressed at DSD using different test environments during the development of an ATO GoA 4 system. The approach focuses on reducing the highly complex, expensive, and time-consuming field tests in the railway sector. DSD will use these test environments for system testing in its AutomatedTrain project.

    5G-RACOM - Field study on hybrid FRMCS networks for a resilient railway radio system | September 2024

    The Franco-German innovation project 5G-RACOM is investigating the efficient, reliable and sustainable utilisation of the FRMCS and its frequency spectrum. As the successor to GSM-R, FRMCS will ensure real-time, high-performance train-to-ground communication based on 5G and thus enable the far-reaching digitalisation of rail operations.

    DB InfraGO integrated Control and Operating System – control system with a future | September 2024

    The integrated Control and Operating System (iCOS) has
    been in full operation as a complete system for a year
    now. The set objectives have been achieved by means of three
    successful commissioning steps under the reference implementation. Systems from four manufacturers have been integrated into the iCOS since September 2023 and they now are
    cooperating successfully with each other in a new architecture
    and with a new interface at various locations.

    Digital Register - the "Single Source of Truth" for the infrastructure data used in fully automated driving | June 2024

    Almost all key functionalities of the digital rail system require highly accurate, up-to-date and digitally available infrastructure data. This is why Digitale Schiene Deutschland is working intensively on a so-called "Digital Register (DR)". It is being specified and standardized as part of the European initiative Europe's Rail Joint Undertaking (ERJU). This should enable all European railroads to access compatible infrastructure data in the future.

    Pan-European Railway Data Factory – infrastructure and ecosystem for fully automated rail operations | April 2024

    Many European railways are striving toward automated rail operations. This requires the collection of extensive sensor data for AI training. A Pan-European Railway Data Factory (PEDF), as a joint infrastructure and partner ecosystem, is seen as a suitable way forward for the sector. This article summarises the highlights and findings of the CEF2 RailDataFactory study undertaken by Deutsche Bahn AG (DB), Société nationale des chemins de fer français (SNCF) and Nederlandse Spoorwegen N.V. (NS).

    Digitalisation and project acceleration as a system solution | February 2024

    End-to-end digital data storage enables the acceleration
    of security projects. Numerous studies have contributed
    to findings with regard to the given facts. Now, it is necessary
    to define a system concept based on these findings
    and to establish initial applications in the immediate future.

    Artificial Intelligence for the traffic management system of the future | January, February 2024

    An intelligent Traffic Management System is a fundamental centerpiece of future digitalized railway network operations. When thousands of trains are on the move in dense traffic, rapid decisions must be made to adjust the operations in the event of disruptions. New approaches are needed in order to be able to respond quickly and effectively to disturbances in future railway operations. Combining Artificial Intelligence (AI) and methods from Operations Research can help address this challenge. This approach was tested on a specific application.

    Digitalising the S-Bahn Stuttgart Core (part 1) | September 2023

    With more than 900 trains per day, the double-track S-Bahn main line in Stuttgart is one of the busiest routes in Germany. After several years of discussion, design and planning, it is one of the first such lines in the world to be equipped with a digital interlocking system (DSTW), European Train Control System Level 2 without signals (ETCS L2oS) and Automatic Train Operation Grade of Automation 2 (ATO GoA 2).

    Article in "Signal & Draht" | FRMCS equipment of 463 multiple units for the Stuttgart Digital Node | 05/23

    In addition to ETCS, ATO GoA 2 and further technologies,
    FRMCS is also being installed as part of the ongoing retrofit
    of 333 multiple units for the Stuttgart Digital Node (DKS).
    130 new regional multiple units will also receive FRMCS “ex

    Article in "Signal & Draht" | Experience gained from track field networking at the Stuttgart Digital Node (part 1) | 04/23

    The first design of a digital interlocking at a large German
    railway node has brought a number of experiences
    to light. The present cabling concept is currently reaching its
    limits, particularly in existing train station areas that are to be
    temporarily equipped not only with European Train Control
    System (ETCS), but also with Class B under the high redundancy
    requirements. A number of optimisations have been developed
    based on this experience.

    Article in "SIGNAL+DRAHT" | Innovative antenna systems for FRMCS -field trials at 1.9 GHz | 11/22

    The Future Railway Mobile Communication System
    (FRMCS) will be the successor to GSM-R. It will be
    based on 5G technologies and will enhance mobile train-to-ground communications in rail operations. Improved radio
    access and core network architectures as well as innovative
    antenna systems in FRMCS will enable higher transmission
    rates, lower latencies and high reliability for any future data
    transfers within the scope of the digitalisation and automation
    of railway services. This article focuses on multi-antenna
    radio technologies and their benefits for FRMCS networks
    at 1.9 GHz
