Key Facts
- Dual Independent Train Detection. SPAS simultaneously uses railway signaling system data and GNSS-based locomotive positioning. This dual-source architecture ensures high reliability even if one data channel becomes unavailable.
- Virtual Safety Perimeter with Personnel Behavior Monitoring. Unlike conventional alerting systems, SPAS does more than issue warnings: • it establishes a virtual safety perimeter, • tracks the real-time movement of each worker, • automatically escalates alarms if personnel remain in the danger zone.
- Simultaneous Alerts for Crews and Locomotive Drivers. SPAS is one of the few systems that alerts maintenance crews and locomotive drivers at the same time, including on adjacent tracks.

Product information
SPAS — Safety Perimeter & Alerting System An intelligent embedded system for safer and more efficient railway operations CTRL+N is an international engineering startup developing embedded solutions for mission-critical infrastructure. Our flagship product, SPAS (Safety Perimeter & Alerting System), is designed to significantly improve safety during railway maintenance and diagnostic works without track closure.
The Challenge Railway maintenance operations involve inherently high risks. Traditional approaches relying on human signalers, limited situational awareness, and the lack of objective monitoring expose personnel to danger while reducing operational efficiency and transparency.
