The Gatekeeper Intelligent Train Undercarriage Scanner (ITUS) keeps trains and cargo moving quickly and safely. Gatekeeper ITUS's industry-leading, railcar undercarriage inspection scanner generates clear, consistent, high-resolution imagery, becoming the "digital fingerprint" of the railcars, which is the foundation for railcar undercarriage inspection and Foreign Object Detection (FOD).


  • Creates a "digital fingerprint" of the train's undercarriage, supporting Foreign Object Detection (FOD)

  • Generates two high-resolution digital images, from two different vantage points, improving visibility in hard to see locations

  • Produces clear, consistent, high-resolution imagery

Multi-Factor Security

Gatekeeper ITUS system provides an extra layer of security when paired with X-ray inspection, radiation detection, or additional Gatekeeper optical inspection systems, including:

  • Enhances data analytics, adding container numbers to the inspection record, when used with Gatekeeper ISCD container code reader
  • Validates the train and its cargo using RFID tag data gathered using Gatekeeper IRID RFID reader
  • Enables better decisions using multi-factor, real-time, actionable intelligence, aggregated by GEMS enterprise software


Gatekeeper ITUS frequently protects passenger and cargo trains, rail loading and unloading points, bridges and tunnels, event security, key industrial facilities, ports of entry, and border crossings.
