Advance Warning System for Track Workers
100% accurate train detection with radar + LiDAR, millisecond alerts up to 10 km — built for tunnels, forests, and valleys.
The Problem — Unsafe Track Work Environments
Track maintenance, doubling, and electrification often occur while trains are active. Manual communication via walkie-talkies is slow, unreliable, and leads to tragic accidents and delays.
- ❌ Manual, people-dependent alert chains
- ❌ Delayed or missed warnings
- ❌ Multi-track ambiguity
- ❌ Harsh terrain and weather constraints
The Solution — Rugged IoT-Based Radar + LiDAR System
A portable IoT-powered radar + LiDAR system that detects trains and instantly alerts work crews via smart hooters and LED indicators — even 10 km away.
Immediate Alerts
Worker safety ensured through smart hooters & LEDs.
Millisecond Detection
Edge-processed alerts with no network dependency.
Reliable Power
Built-in rechargeable battery for remote operation.
All Terrain Operation
Performs in tunnels, forests, cuttings, and bridges.

Frequently Asked Questions
Does it work without network?
Yes — local detection and hooter alerts continue even offline. Data syncs automatically when network restores.
Can it handle multiple tracks?
Yes — it distinguishes between directions and multiple tracks using dual radar mapping.
Can we host the system on-premises?
Absolutely. Both cloud and on-premises deployments are supported with full RBAC and white labeling.
