Which particularly urgent digital solutions in German rail transport should realistically be prioritized?
Marc Ludwig: Passenger and freight rail transportation faces major challenges worldwide. The increasing demand for mobility due to urbanization and population growth – 68 percent of the world's population is expected to live in cities by 2050 – coincides with the goal of significantly reducing emissions in the transport sector. This sector currently accounts for around 23 percent of global greenhouse gases. Rail transport plays a key role as the most environmentally friendly means of transportation. In order to meet the challenges, we need solutions – above all digital solutions – to modernize rail transport. Siemens Mobility is well positioned worldwide in this area and is already the market leader with its products. The introduction and further expansion of modern control and safety technology such as the European Train Control System (ETCS) is particularly important in long-distance rail transport. ETCS digitalizes train control and increases efficiency and interoperability, especially for international connections. This will allow more trains to run on existing long-distance railway lines. Modernizing the infrastructure with ETCS makes long-distance transport future-proof.
And what about local transport on short commuter routes?
We are also pressing ahead with the modernization and digitalization of signaling technology in local rail transport. Communications-Based Train Control, CBTC, plays a key role in this: with CBTC, train traffic is monitored in real time and controlled with high precision. This means that metros and subway trains can run at much shorter intervals – and thus significantly increase capacity in metropolitan areas. In addition, with Signaling X, we have developed a cloud-enabled signaling solution that significantly increases system efficiency, capacity, and reliability in both metro and long-distance transport, enables energy savings, and ensures maximum safety. Signal boxes and other control and safety technology functions are virtualized and outsourced to cyber-secure rail data centers. This makes today's wired, trackside infrastructure redundant, which significantly reduces maintenance costs, for example, and makes operations more flexible and scalable.
What can increase the chances of implementation?
Germany is not yet at the level of other European countries when it comes to digitalization and modernization of the rail network – which is of course largely due to the size of the network. Nevertheless, there are European countries that have already digitalized more than half of their rail infrastructure, while Germany is currently at less than two percent. The expertise is available in the German railroad industry. Funding has also been provided. The task now is to accelerate implementation. This requires efficient processes and secure long-term investments in order to provide planning security to the industry.
Siemens is a major technological partner in the rail system. What role does train equipment, for example, play in digitalization?
So, first of all, we have cutting-edge technology on offer. This applies to both long-distance and local rail transport. This technology is already used worldwide. The focus is also on equipping rail vehicles with on-board units (OBUs), as these form the basis for future-proof and interoperable operation. The systematic retrofitting of trains with digital control systems is crucial to ensure that we can operate the lines efficiently and safely by 2035. At the same time, we focus on centralizing control functions in digital rail data centers in order to manage the network holistically, intelligently, flexibly, and sustainably. This is how we are shaping the rail infrastructure, making it fit for the future and creating the conditions for modern, efficient passenger transportation.
