Climate change and growing traffic volumes will increase the importance of rail transport in the coming years. Studies show that a 10.5 million tons reduction in CO2 emissions per year can be expected as a result of the transfer of transport to railway. In addition, doubling the number of long-distance rail passengers and increasing market share of rail freight could save several million car and truck trips and thousands of air travel.
In order to cope with the increase in the number of railway services, as well as improve the reliability and punctuality of the railway, Deutsche Bahn intend to strengthen their infrastructure and continue to devote themselves to serving customers. In particular, the following steps are planned: expansion of the route network including building new routes and transport nodes, introducing digital technologies into railway operating processes, creating additional terminals for freight traffic, as well as increasing the number of rolling stock and improving maintenance.
In the field of control and signalling systems, the widespread introduction of the European Train Control System (ETCS) and a new generation of microprocessor-based centralization, as well as a new strategy for train traffic control are in the coming years planned. The introduction of these systems will reduce the number of failures, increase the number of train movements, and increase the train speed. The listed systems are the basis of the digital railway system.
A digital railway system presupposes a complex system architecture characterized by a high degree of automation and a large number of new technologies. Consequently, the railway system of the future contains a number of vulnerabilities subject to external interference. Due to the criticality of the railway system to the economy and society, any attack, even if it does not lead to personal injury, can cause significant financial damage to the railway sector. This leads to the fact that the topic of security in general and IT security (information security) in particular becomes more and more important for the railway sector.
Within the ERASMUS and project, TUD focuses on control and signalling systems and offers a series of lectures covering both system solutions and their practical implementation on railways in Germany.
The lecture series consists of the following sessions, each of which lasts 90 minutes:
- ETCS (European Train Control System) – Special Problems
- The NeuPro – ESTW (Computer-based interlocking)
- New Operations Management Concept of DB
- Security in Railway Transport
ETCS (European Train Control System) – Special Problems
For the first time in the history of railway traffic, the international train control system ETCS (European Train Control System) enables uniform and interoperable technology in large parts of Europe. In addition to the technical harmonization, the adaptation of the national rules and the
integration into the functions of ETCS defined by the subsets represent the greatest need for development. The lecture “ETCS – special problems” shows, based on the in-depth knowledge about the function of ETCS, the challenges in practical use in Germany. Here, some issues are taken into account, such as:
- Effects of the braking curves on time-critical infrastructure objects,
- Different types of hybrid equipment,
- Application of a train-protecting signal as well as
- Transfer of faulty points
In addition, we use these examples to show the current needs for development when using ETCS.
The NeuPro – ETSW (Computer-based interlocking)
DB Netz AG currently operates around 2,500 interlockings. However, there are many different types of interlockings – from the mechanical lever interlocking from imperial times to the modern digital interlocking (DSTW). In order to increase the reliability, quality and economic efficiency of the train control and safety technology, earlier interlocking types are being replaced by a further development of the electronic interlocking, which is so-called digital interlocking. In the lecture “The NeuPro – ETSW (Computer-based interlocking)”, the knowledge about goals of the NeuPro-ESTW and its system structure at the DB is imparted.
New Operations Management Concept of DB
Since the beginning of the 21st century, operations management for the long-distance and metropolitan network has been carried out at DB (Deutsche Bahn) by seven control centers. The extensive automation and digitization of the train control and safety technology, and others, characterized by the ongoing planning by DSTW, as well as the introduction of ETCS, represent the operational management concept of DB, which has been used so far.
The future is seen in the new operational control strategy (BSS), which provides for decentralized operational management from regional control centers. In the lecture “New Operations Management Concept of DB”, a general overview of the background to the change in strategy is given and the integrated control and operating system of the DB is presented.
Security in Railway Transport
Safety has already been researched in its essential fundamentals in train control and safety technology and there are fundamentals and standards that are consulted and used for practical implementation. Along with the development of advancing digitization, IT-supported systems for control and safety technology are also increasingly being used in the future. In the lecture “Security in Railway Transport”, an overview of IT security and its requirements is given, basic IEC norms and standards are presented, the special problems of IT security for applications of control and safety technology are presented.
