X-Ray Train Inspection Scanning System
The Madoors USA Madoorsscan S-5500 is a high-energy X-ray drive-through train inspection system that allows inspection of rail cargo wagons and containers for correspondence to accompanying documents and detection of weapons, explosives, narcotics, smuggled goods, and concealed persons — without cargo unloading or wagon unsealing. Powered by a 6 MeV generator with 300mm steel penetration capability, the S-5500 scans up to 300 containers in 10 minutes at train speeds up to 30 km/h, delivering separate high-resolution side-view X-ray images for each wagon to an ergonomic operator workstation with customizable image processing tools, automatic container code recognition, and Customs EDI network integration for remote analysis, knowledge sharing, and automated cargo verification.
Using no radioactive source — the X-rays are generated electrically — the S-5500 provides a radiation-safe train inspection solution that significantly reduces the necessity of manual inspection and cargo unloading at rail border crossings, customs checkpoints, and freight inspection facilities.
TECHNICAL SPECIFICATIONS
The Madoorsscan S-5500 train drive-through X-ray inspection system consists of an ionizing radiation source generating 6 MeV X-rays, a detection and data transfer system, a signal control and processing unit installed in the scanning portal, an acquisition and analysis workstation, protective rooms for system arrangement, and protective shielding providing radiation safety for all personnel in the vicinity.
The 6 MeV generator provides the X-ray energy level required for penetration of 300mm of steel — confirming imaging capability through the full wall thickness of standard ISO shipping containers, reinforced wagon bodies, and dense metallic cargo loads that would stop lower-energy inspection systems. At the optimal scanning speed of 15 km/h, the system delivers the highest image quality with maximum penetration depth. At the maximum operational speed of 30 km/h, the system maintains effective scanning capability for all standard cargo inspection requirements — allowing trains to pass through the inspection portal at low-speed operational velocity without requiring full stopping.
Throughput is 300 containers in 10 minutes at optimal scanning speed — equivalent to 30 containers per minute or 1,800 containers per hour. This exceptional throughput rate makes the S-5500 the appropriate specification for the highest-volume rail cargo inspection requirements at major international border crossings and port rail terminals where the inspection of each complete train set must be completed within the available time window without creating significant schedule disruption.
The system generates a separate X-ray image for each individual wagon — allowing the operator to review each wagon's cargo independently rather than interpreting a continuous image of the full train length. Automatic container code recognition links each wagon image to its associated customs dataset — providing instant access to the declared manifest for comparison with the X-ray image content.
No radioactive source is used — the X-rays are generated by the electrical accelerator, which can be switched off when not scanning. This non-radioactive source design eliminates the regulatory licensing, safety management, and emergency response requirements associated with permanent radioactive source-based inspection systems.
Customs EDI network integration allows the S-5500 to communicate directly with customs electronic data interchange networks — receiving declared cargo data before the train arrives and transmitting inspection results after the scan. Multiple S-5500 systems can be networked together for remote analysis, comparison, and knowledge sharing across a national or international rail inspection network.
KEY FEATURES
300 Containers in 10 Minutes — Exceptional Rail Throughput
The S-5500 throughput of 300 containers in 10 minutes at optimal scanning speed provides the highest available rail cargo inspection rate — allowing complete inspection of a standard freight train in a single 10-minute pass through the inspection portal without stopping. This throughput rate transforms rail cargo inspection from a manual, time-consuming, wagon-by-wagon operation into an automated, high-speed screening process that does not create significant delays in the rail freight schedule.
No Cargo Unloading — No Wagon Unsealing
The non-intrusive X-ray inspection eliminates the requirement to unload cargo or unseal wagons for inspection — maintaining the integrity of sealed cargo consignments, reducing inspection time from hours to minutes per train, and eliminating the handling damage and contamination risk of manual inspection. This sealed-wagon inspection capability is the primary operational advantage of X-ray train inspection over all conventional manual inspection methods at rail border crossings and customs checkpoints.
6 MeV — 300mm Steel Penetration
The 6 MeV generator provides sufficient X-ray energy to penetrate 300mm of steel at 15 km/h scanning speed — covering the full wall thickness of standard ISO containers, reinforced wagon bodies, and any metallic cargo loading configuration encountered at rail freight checkpoints. This penetration capability ensures that no cargo can be concealed behind a metallic shield within the wagon that would block the X-ray image and create an uninspected volume.
No Radioactive Source — Safe Operation & Simplified Licensing
The electrically generated X-ray source eliminates the regulatory licensing, security, and emergency response requirements associated with radioactive isotope-based inspection systems. The source can be switched off when not scanning — eliminating the continuous radiation management requirements of permanent source systems and simplifying the operational safety procedures for checkpoint staff working in the vicinity of the inspection portal.
Separate Wagon-by-Wagon Images — Ergonomic Operator Interface
The separate image delivery for each individual wagon provides the operator with a focused, manageable image for each inspection unit — rather than a continuous image of the full train length that would require the operator to manually locate wagon boundaries and correlate image positions with wagon identities. The ergonomic operator interface provides customizable image processing tools — colorization, enhancement, comparison, and zoom — for each wagon image, supporting effective interpretation and rapid threat identification across all wagon types and cargo densities.
Automatic Container Code Recognition — Instant Dataset Access
The automatic container code recognition option reads the container identification code from the X-ray image and instantly retrieves the associated customs declaration dataset — providing the operator with the declared cargo manifest for the container being reviewed at the moment the X-ray image is displayed. This instant manifest access allows the operator to compare declared and actual cargo content simultaneously without manual data lookup — directly supporting manifest verification and contraband detection efficiency.
Customs EDI Network Integration — Automated Compliance
Direct integration with Customs Electronic Data Interchange networks allows the S-5500 to receive pre-arrival cargo declarations before the train enters the inspection portal — enabling pre-screening risk assessment — and to transmit inspection results automatically after the scan to the customs management system. This automated two-way data exchange eliminates manual customs data entry at the inspection checkpoint and provides real-time inspection result integration into the national customs compliance management system.
Multi-System Network — Remote Analysis & Knowledge Sharing
Multiple S-5500 systems at different border crossings and rail terminals can be networked together — allowing remote analysis of suspicious cargo images by centralized expert analysts, comparison of cargo images across multiple inspection sites to identify serial smuggling patterns, and knowledge sharing of threat image libraries across the complete national rail inspection network. This network capability transforms individual inspection checkpoints into nodes in an integrated national rail security intelligence system.
Contraband, Weapons & Concealed Persons Detection
The S-5500 detects the full range of rail cargo security threats — explosive materials and IED components through density and shape recognition, narcotics as organic density masses, weapons and firearms as metallic objects, smuggled cigarettes and consumer goods as characteristic stacking patterns inconsistent with declared cargo, and concealed persons as organic density objects within cargo loads. The 6 MeV penetration and organic/inorganic discrimination capability ensure that concealment in dense cargo, behind metallic shields, and in structural wagon compartments does not defeat detection.
Powerful Customizable Software — Image Processing Tools
The powerful operator software provides customizable image treatments, processing options, and comparison tools for effective cargo image interpretation — supporting both real-time inspection and retrospective analysis of recorded images. Platform upgrade capability allows the software to be enhanced with new features and detection algorithms as they become available — protecting the investment in the inspection system infrastructure against obsolescence as threat profiles evolve.
