Vehicle-to-Rail Sidelink for Zero-Accident Railway Grade Crossings

V2Rail bridges rail Positive Train Control (PTC) systems with automotive C-V2X transceivers, delivering direct train-to-car collision warnings up to 2 kilometers before rural and urban grade crossings.

Stopping Trains and Cars from Crossing the Same Point in Time

Railway grade crossings are high-fatality intersections where heavy freight trains require miles to stop. V2Rail broadcasts locomotive speeds, braking curves, and estimated crossing arrival times directly into approaching car displays.

Core Engineering Areas

• Grade Crossing Collision Preemption Systems — Delivering early auditory and visual warnings to drivers approaching blind railroad crossings.
• Positive Train Control (PTC) Sidelink Bridge — Translating heavy rail safety protocols into standardized automotive Cooperative Awareness Messages.
• Low-Latency Train Tracking Telemetry Over RF — Ensuring continuous sidelink connectivity through deep railway rock cuts and canyons.
