Digital Signalling and Control Systems Test Centre (TC dLST)
The Digital Signalling and Control Systems Test Centre (TC dLST) forms part of the reference environment for the development, integration and validation of digital signalling and control systems (dLST). It enables the systematic testing and safeguarding of the technical interaction between all relevant subsystems prior to their deployment on the rail network.

Digital Signalling and Control Systems Test Centre (TC dLST)
The dLST Test Centre was designed and implemented by DB InfraGO AG in order to systematically test digital components of railway infrastructure for functional reliability prior to field deployment and to ensure their technical interoperability within the overall system.
A key task of the Test Centre is the integration of all digital subsystems of the new signalling and control technology into an interoperable overall system. In addition to the actual interlocking and operator interface components, this includes secure transmission systems for cross-site networking as well as management systems through which signals, points and other infrastructure elements are controlled and monitored from digital control centres.
To achieve this, the Test Centre establishes dedicated test and reference environments in which both functional verification of individual subsystems and system integration tests are conducted. In addition, quality assurance procedures, tests of commissioning and maintenance processes, as well as simulation-based analyses for identifying and resolving potential faults during later operational phases of the digital signalling and control systems are carried out.
Project Objectives
The objective is to relieve implementation projects — particularly those involving digital interlockings — through early and systematic technical validation. This approach is intended to accelerate commissioning processes and significantly reduce technical risks and operational disruptions during the rollout phase.
For example, extensive tests of transmission systems for the “Digital Node Stuttgart” project were successfully conducted at the Test Centre, and the results were subsequently incorporated into the project’s implementation.
