Railroad VACIS® Imaging System

Rugged, around-the-clock nonintrusive imaging for rail applications.

The Railroad VACIS® imaging system helps trained operators see the contents of closed, moving railcars, assisting them in intercepting weapons, contraband, and other items of interest and verifying shipping manifests. The system's rugged design resists corrosion, humidity, rain, and wind, making it an ideal choice for around-the-clock scanning in challenging environments such as remote border crossings.


Featuring rugged gamma-ray imaging technology proven in hundreds of VACIS systems installed around the globe, the Railroad VACIS system is an ideal imaging solution for border crossings or wherever nonintrusive imaging of rail equipment is required.


The Railroad VACIS imaging system scans trains of any length. As the railcars move through the system without stopping, their images are individually saved along with a high-resolution digital video snapshot of the car identification number. Coupling sensors automatically identify the beginning and end of each railcar, allowing segmentation of the train into individual railcar images. Speed sensors mounted on tracks allow for constant aspect ratio in images despite changes in train speed.

Our patented detector technology allows trained inspectors see the contents of closed railcars through more than five inches of steel. The system's direct radiation dose per scan to cargo is extremely low, and the scatter dose to locomotive occupants, operators, and bystanders (who are never scanned directly) is even lower.


Leidos is a world leader in nonintrusive imaging technology, with hundreds of systems installed for government and commercial clients around the world. Every VACIS system is backed by our dedicated installation, training, maintenance and technical support.
