Train Rider Detection System (TRiDS™)
A large rail company in the western United States (company name cannot be disclosed)
runs freight trains along the border between the U.S. and Mexico. Trains are often comprised of
flat cars hauling metal shipping containers and are extremely vulnerable to stowaways (illegals)
and cargo theft. Distances are vast, authorities overextended, and railroad profitability dependent
upon maintaining train velocity - strict schedules ensure timely intermodal transfer. Stop and
search protocols are ineffective, sporadic, and waste time. The
Train Rider Detection System
(TRiDS™) is Duos’ solution to this critical border security problem.
TRiDS™ automatically captures inspects and processes real time images from freight
trains moving at speeds of up to 70 mph, digitally searching for unauthorized riders and minimizing
the need to stop trains for inspections - with the objective to maintain train velocity throughout
the route. Three levels of technology combine to form TRiDS™, providing highest level of accuracy,
minimizing false alarms, and offering the optimum solution for intrusion detection.
Specialized high speed cameras capture digital still images of each container car
as it passes through a nondescript checkpoint. Images are processed to analyze container wells
for anomalies. For instance, a person hiding in the container well does not fit expected geometry
and is therefore flagged as a suspicious anomaly. Digital images of suspicious anomalies are
transmitted using a custom browser based interface and user-friendly GUI accessible from the
customer network. Slow motion image playback allows operators to quickly review suspect container
cars. Archived images can be downloaded for review as required.
Thermal camera technology provides additional images for analysis. Thermal
technology substantially increases accuracy of unauthorized rider detection, as thermal cameras
illuminate heat sources for anomalies and show them in color.
Container Radio Frequency Identification (RFID) Tag Monitoring - electronic
RFID tags provide container identification and “lock” containers. An RFID reader verifies tag
integrity as trains pass through the checkpoint. Broken or compromised tags generate an alarm,
and rapid analysis enables law enforcement personnel to determine if, when, where, and which
container has been breached, and indicates container location and pinpoint train boarding
locations. Ruggedized handheld RFID readers enable railroad personnel to verify tag status within
a radius of 100 feet.
Remote Viewing provides real time electronic inspections and archived data access
for customer security personnel, the U.S. Border Patrol and other agencies, reducing the need to
deploy field personnel and rendering inspections more efficient and effective through leveraging
the technology. TRiDS™ minimizes the need for interaction in that it cues Border Patrol officers
and/or other law enforcement personnel which rail cars warrant investigation.
