Interlocking Design Automation

A more cost-efficient, safe and reliable concept for interlocking solutions for the future

Current Signaling Solutions

Cost of change

Most interlocking system projects today are developed with the following characteristics:

  • Errors are found late
  • Late changes are costly
  • Schedules to deliver interlocking software are long and unpredictable

Root causes

The root causes for these problems include:

  • Vague and imprecise requirements
  • Design, test and safety assessment is based on repetitive and manual work, and requiring senior skills
  • Lack of standard interfaces

Main principles of interlocking design automation

To deliver the cost-efficiency that future railroads need, a new solution for interlocking design automation is needed, based on useful requirements that need to:

  • Be precise, to enable automated development
  • Separate safety and test principles, to enable 100% coverage proof of safety and automated functional test
  • Use standard interfaces where possible, to make it cost-efficient to replace individual sub systems

The process for interlocking design automation

The modern interlocking design automation process needs to start with the following step:

  • Gather and analyze requirements, applicable standards, interfaces, rules & regulations and scope
  • Determine the system’s principles
  • Determine how configuration of principles is to be done for individual systems

Based on the above, the next step is to define the principles as a formal specification library, with:

  • The object model defining the underlying ideas and objects, along with their properties and relations
  • Separation of design, test and safety principles, based on the object model
  • Configuration of individual systems, to apply the principles

With the above two steps completed, the concept of interlocking design automation can be realized using modern software tools:

  • Automated generation of design and revenue service code based on (reusable) principles
  • 100% coverage proof of safety and automated functional test of each system developed
  • Efficient support for change in principles and requirements

Our Solutions

Meeting the higher demands for capacity is a major challenge for the railway industry. The ability to deliver rail infrastructure both fast and cost-efficiently is a critical success factor. Our solutions are developed for today’s complex digital train control.
