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.

Digitalisation of control and safety technology

To assure the future viability and performance of the rail network, various initiatives and programmes to digitalise railway infrastructure have been launched in Europe.

This includes programmes such as EULYNX, RCA (Reference CCS Architecture) and Europe’s Rail Joint Undertaking (with system pillar and innovation pillar), which aim to automate systems to secure, schedule and control railway traffic. National programmes such as Digital Rails Germany from DB Netz AG have comparable aims too.

The systems engineering solutions from SIGNON actively support these aims, particularly in the areas of concept creation and specifications.

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.

Due to different standards between countries or within a single country, train control system have existed in different forms for decades. In addition to different forms of monitoring, the stage of development of the respective technology used also differs. These technical differences regularly pose challenges for the workers involved when operating existing systems or for migration 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


  • 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
