Preventing Fatal Railroad Accidents

Reliable and redundant technology for smarter worker protection


A Roadway Worker Protection System
by Miller Ingenuity

ZoneGuard, the most advanced RWP system on the market, provides reliable and accurate protection by leveraging modern technological advances. It is the only worker safety product on the market to utilize diverse and redundant train detection sensors connected to a wireless mesh data radio network. This provides coverage for long protection zones typically required on freight and passenger rail operations and virtually eliminates all false alerts caused by inaccurate detection typically found on other RWP systems on the market. ZoneGuard has also been successfully tested in challenging scenarios including through long curves, high noise urban environments, multi-track detection, and even directly under high power lines.

The system was specifically designed to meet FRA recommendations of adopting electronic protection to coincide with existing worker protection safety rules. ZoneGuard’s goal is not to replace, but to strengthen the standards that are in place for track worker safety.

Adopting ZoneGuard as your secondary worker protection system also increases your available track maintenance time. The RWIC and crew will receive an alert on their personal alert devices from a network of either portable or fixed train detection modules that detect track vehicles over multiple miles of railroad track. Once the train has cleared the zone, the RWIC can quickly return their crew members to the track, allowing for a safer and more efficient work zone as well as increasing train velocity.

This eRWP safety solution can be installed affixed to permanent structures such as a catenary pole or transported to each job-site using Miller’s compact and lightweight portable unit.

While not requiring on-board installation to operate, the system’s on-board component can provide real-time on track vehicle location information to provide precise warnings to train operators and workers when approaching an active work crew, and can allow for PTC integration through future updates.

Additionally, ZoneGuard's cloud-based Web Dashboard provides customers with real-time worker/work zone information, as well as, many key efficiency and safety performance reports to ensure that workers are working in compliance with federal and customer specific safety rules. The dashboard also lets Miller Ingenuity support staff monitor real-time diagnostics and system performance, collect train detection information logs, and provide remote updates to the system for continual system enhancement and quick and seamless system updates.
