Precise, Reliable Data Exchange Between Trackside Infrastructure and Onboard Control Systems

TrackLink®4 is a SIL2-rated track-to-train communication system designed to deliver precise, reliable data exchange between trackside infrastructure and onboard control systems.

The system comprises a redesigned onboard reader and a passively powered trackside beacon, operating together to provide accurate, location-based control inputs to the Train Control and Management System (TCMS).

Operational Safety, System Performance and Cyber Security

• • SIL2-rated outputs for safe integration with onboard control systems
  • Native Ethernet connectivity as an optional alternative to the serial interface
  • Modular protocol support for integration with a wider range of TCMS architectures
  • Doubled data payload from 6 to 12 bytes
  • Dual-tag beacon configuration for improved read reliability at speeds exceeding 200 km/h

TrackLink®4 is designed for deployment across both heavy rail (mainline) and light rail/metro environments, supporting a broad range of passenger, traction and safety applications. The system is developed in accordance with IEC 62443 security principles and is aligned with the Cyber Resilience Act.
