The Power of Intelligent Simplicity
Traditional detonators and manual fog-signaling have now evolved into a GPS-based digital aid. FogSafe® accurately identifies the train’s position and gives timely pre-warnings for signals, level crossings, and critical landmarks
through audio-visual alerts, allowing the Loco Pilot to focus on safe driving. Its simplified display and human voice
prompts minimize distraction and ensure total situational awareness.
