Revolutionizing Railcar Tracking with SMRTag™

​

For nearly two decades, we have led the way in North American industrial logistics solutions. Now, we are redefining railcar inventory management with our cutting-edge SMRTag™ system, a fully automated solution designed to streamline railcar tracking for industrial railyards. Utilizing advanced IoT-based location and asset management technology, SMRTag™ enables seamless, single-point collection of multiple railcars, improving efficiency for industrial shipping and storage operations.

We continue to expand SMRTag™ capabilities for in-transit train monitoring, delivering real-time railcar consist and health data. This innovation allows onboard consolidation of car-specific and consist-wide telemetry, providing greater visibility and control over rail assets.

Smarter, Safer, and More Efficient Railcar Inventory

​

Traditionally, railcar inventory tracking has relied on manual record-keeping or individual scanning—time-consuming, labor-intensive, and potentially hazardous processes. Our SMRTag™ system transforms this approach with our proprietary SMRTMesh™ network, which uses strategically placed, battery-operated, ground-mounted anchors to pinpoint each SMRTag™-equipped railcar’s exact position. This automation dramatically improves inventory speed and accuracy, reduces manual workload, and enhances worker safety.

​

Seamless Integration with Industry Standards

​

SMRTag™ is fully compatible with AAR railroad standards, enabling real-time train location and sequence tracking. Our system processes millions of data points per second, ensuring robust and resilient communication while dynamically understanding and monitoring railcar organization within any consist.

Additionally, the SMRTag™ Open API integrates seamlessly with sensors to track critical conditions such as impact, pressure, load status, and temperature, enhancing safety and optimizing rail asset and cargo management.

At INet, we are committed to continuous innovation, delivering smarter, safer, and more connected solutions that transform industrial rail logistics.
