DerailGUARD

High-Visibility Derail Status

DerailGUARD makes derail status unmistakable at a glance, providing multi-layered confirmation of derail status with activation of emergency braking as needed. A clear yard-side status signal paired with an on-screen alert on the YardGUARD in-cab display helps teams confirm conditions before a move — reducing preventable damage, delays, and disruption.

Part of YardGUARD’s real-time safety intelligence system – helping teams verify conditions and proceed with confidence.
