Digital interlocking (DSTW: Digitales Stellwerk) Meitingen-Mertingen
The Meitingen-Mertingen digital interlocking is an important Deutsche Bahn project for a high-speed line in regional and long-distance traffic with line speeds of up to 200 km/h. In the process, two relay interlockings in Meitingen-Mertingen were replaced by modern technology.

Technology fields
Digital interlocking Meitingen-Mertingen
The Meitingen-Mertingen digital interlocking (DSTW) is the first of its kind on a Deutsche Bahn high-speed line for regional and long-distance traffic with line speeds of up to 200 km/h. At the same time, it is one of three pre-series projects for digital control and safety technology (DLST) and is located on the Scandinavia-Mediterranean TEN corridor. This section between Nuremberg, Augsburg and Munich is a central component of the Digital Rail Germany (DSD) infrastructure project.
The double-track line 5300 was equipped with state-of-the-art safety technology (DLST). Construction work began in February 2019.
Implementation
To accommodate the new signaling technology, track concentrators (GFK) were built in the Meitingen and Mertingen stations as well as a data center for the technical and operating site (TSO/BSO). The technical site was newly developed in accordance with industrial standards and offers maximum availability and protection for the signaling technology. In addition, high-performance and high-availability solutions were implemented for the data and power supply of the signals and points in order to maximize the reliability of the signalling technology.
A key component of the project was the development and implementation of a protection concept against cyber attacks. For this purpose, a Security Operations Center (SOC) was set up in Frankfurt, which monitors and analyzes the entire communication on the Meitingen-Mertingen line in 24/7 mode.
When the DSTW in Meitingen-Mertingen was commissioned, the former signaling systems and two relay interlockings were replaced by Hitachi technology from GTS (Ground Transportation Systems). This ensures
- More safety
- Increased reliability
- Increased efficiency
- Improved operating comfort
- Long-term cost savings
InfraGO AG is thus implementing the legal requirements for critical infrastructures and is a pioneer in this field in Europe.
As part of the pre-series projects (VSP), the new digital interlocking - (DSTW) - with modular interchangeable components was tested and prepared for the subsequent series projects.
Benefit:
- Qualified testing of all processes, subsystems and also of the overall system of digital signaling technology (DLST)
- A secure basis for the realisation of series projects
