Interoperable SCWS Safety System with EULYNX Interface is powered by Schweizer Electronic

Schweizer Electronic is Europe’s market leader in automated on‑track protection for busy railways. The company develops SIL4‑certified warning systems for track‑site workers and has expanded its portfolio with non‑SIL geofencing devices. These systems alert workers on or near the track, improving safety on construction and maintenance sites.<br/><br/>To further reduce work interruptions and optimise operations, Schweizer Electronic is developing signalling‑based warning solutions (SCWS) using standardised interfaces such as those between ILTIS and interlocking systems or EULYNX‑compliant connections. The technology is under development and ready for pilot implementation.

Why Automated Track Worker Safety System with Interface-Adapters?

A SIL4 PoC for worksite protection that minimises interruptions and improves maintenance efficiency by using real‑time interlocking data and automated route‑specific warnings. Its adapter‑based architecture ensures backward compatibility, while its EULYNX‑compliant design enables readiness for ETCS Level 2. This protects lifecycle investments, strengthens safety and cybersecurity, and positions operators for a vendor‑independent future.

Benefits

  • Provides timely, track‑specific worker protection warnings, enabling more efficient, coordinated, and safer maintenance activities on and around the track.
  • Delivers a modular, standardized end‑to‑end solution with a flexible digital architecture that meets the high operational demands of maintenance and asset management. Its modularity enables scalability, rapid deployment, and cost efficiency across diverse rail environments
  • Supports existing infrastructure through a modular adapter framework, enabling seamless integration with legacy interlockings — including older generations and ILTIS‑connected systems — without costly redesign or replacement.
  • Simplifies handling of network topology changes, reducing effort in locations where traditional permanent warning systems require repeated engineering updates for every infrastructure modification.
  • Ensures long‑term viability through full digitalization and EULYNX‑compliant interfaces, providing high levels of safety, cybersecurity, and flexibility to meet evolving customer needs, including the integration of train protection functions.
