ARiS: The Integrated Platform for the Digital Railway of Tomorrow

The demands placed on modern rail vehicles continue to increase. Digitalization, cybersecurity, functional safety, and long-term availability must be considered today to meet future market and regulatory requirements.

With ARiS (Automated Railway integrated System), Selectron introduces its new product generation for rail vehicle automation. ARiS combines control, networking, and automation in a modular platform and provides the foundation for future Train Control and Management Systems (TCMS), networking, and automation solutions. Functional safety and cybersecurity are considered at the platform level from the outset.

From Individual Components to an Integrated Platform

Unlike conventional approaches, where individual components and functions have to be integrated later, ARiS was designed from the outset as an overall system encompassing hardware, software, tooling, and functional safety and cybersecurity requirements. The MOS operating system and engineering tools support development, programming, configuration, testing, and commissioning. This platform approach reduces interfaces, minimizes integration effort, and lays the foundation for more efficient engineering processes.

Secure by Design

Functional safety and cybersecurity are integral to the ARiS platform approach from the outset. ARiS also takes the requirements of the Cyber Resilience Act (CRA) into account. The successful IEC 62443-4-2 SL-C 2 certification of the CPUs and expansion modules underscores the high priority placed on cybersecurity within the platform and helps reduce development and approval risks.

One Platform for Different Applications in Initial Pilot Projects

Thanks to its modular architecture, ARiS is suitable both for comprehensive Train Control and Management Systems (TCMS) and for individual subsystems such as HVAC or door control, as well as retrofit projects and decentralized automation concepts. Local and distributed I/O modules allow the system to be expanded step by step. The platform is complemented by services such as technical support, retrofit solutions, and long-term availability services.

The platform is already being used in initial customer and pilot projects and is continuously being enhanced based on real-world requirements from the rail market. Close collaboration with vehicle manufacturers and operators ensures that new functions and technologies are incorporated into the platform with a strong focus on practical application. We will soon share more about these initial applications and the success stories emerging from them.

Designed for Long Life Cycles

Another key focus is long-term investment protection. With a life cycle of up to 30 years, a stable architecture, and continuous development, ARiS supports the sustainable modernization of vehicle fleets across multiple vehicle generations. ARiS will be available for new development and modernization projects starting in 2027.

Developed in Switzerland and based on decades of experience in rail technology, ARiS combines Swiss engineering expertise with the requirements of modern, safety-relevant rail vehicle systems. The result is a platform that reduces complexity, provides long-term future readiness, and opens up new possibilities for the digital railway.
