Systems Engineering – from an idea to its implementation

Support at every phase of your project.

SIGNON has a multi-disciplinary team from the Systems Engineering Department on hand to assist you at all times. Whether you are right at the start of a pioneering digitisation project or are in the crucial implementation phases of a train control system roll-out, you can rely on us.

Digital control and safety technology

In order to make rail traffic future-proof and high-performing, several companies have started implementing programmes to digitise the railway infrastructure.
There are various programmes in Europe alone, such as “Digitale Schiene Deutschland” (DB Netz) and EULYNX (DB Netz and 11 other European operators), with the aim of digitising and automating the systems in place to schedule and control rail traffic.

Train control

Train control systems play a key role in the smooth interaction between all components in the overall rail system: They ensure the secure monitoring of all trains travelling within a rail network and, in doing so, make a significant contribution to improving rail traffic safety.
There have been different forms of train control systems in place for many decades, brought about by different standards between the countries or even within a particular country. In addition to the different forms of monitoring, there are also differences in the development status of the respective technology in use. These technical differences pose regular challenges to the responsible persons for operating the existing systems or migrating to new systems.
The Systems Engineering solutions from SIGNON provide the right support at this point, from the concept creation through to the system integration and commissioning.

Our services in Systems Engineering

Concept creation and requirements management

  • Creation of concepts for the use of novel technical systems (e.g. systems for automated rail operation)
  • Specification of requirements documents (e.g. functional and non-functional requirements)
  • Model-based specification with SysML / UML or ARCADIA, for example (e.g. digital signal boxes, light signals, free track detectors)
  • Further development of requirements (change management)
  • Assessment of requirements

Impact and conformity analyses

  • Drafting of impact analyses (e.g. safety, operations)
  • Drafting of conformity analysis (e.g. functional specifications for specifications, requirements for TSI specifications)

System integration and test supervision

  • Specification and implementation of test cases for the subsystem test, system integration and acceptance of control and safety technology systems
  • Planning and supervision of test runs
  • Evaluation of test runs
  • Analysis and evaluation of test anomalies
  • Concepts and assessments for the integration of subsystems into overall systems
  • Drafting of migration concepts

Commissioning

  • Drafting of commissioning concepts
  • Supervision of commissioning

Verification and validation

  • Verification of requirements
  • Verification of processes
  • Validation of requirements
  • Simulation: Creation of executable system logic models to test out and validate system behaviour
