Automated Train Inspection  – Inspect

Reduce Rolling Stock Maintenance Costs with Our Automated Visual Camera Inspection Technology

Technological systems require regular railway maintenance to ensure that they live up to the strictest safety and performance requirements. Train maintenance is generally performed in regular intervals by specifically trained personnel to ensure a long service life and to keep component wear and tear to a minimum. Visual Inspections are usually carried out by qualified technicians. But people can make mistakes.

PSI Technics offers sophisticated and fully customizable camera solutions that complement or even replace visual and manual tests and inspections.

PSI Technics' industrial image processing solutions use camera technology and laser sensors. They are ideal for automated maintenance workflows, guarantee a safe operation and maximum performance. They significantly increase the inspection quality while drastically reducing maintenance intervals.

How the automated train inspection works:
  1. The Inspect software module records images of the train while the train passes the system.
  2. The system automatically records all required images for all required components.
  3. The Analytics diagnostic software analyzes the recordings and displays the results.
  4. The maintenance crew accesses and reviews the analysis results via an intuitive web interface.
  5. The recorded data are can be harnessed to analyze and optimize maintenance processes.

Maintenance benefits of automated train inspection


The system's automated camera technology optimizes the rolling stock maintenance workflow on an ongoing basis. Visual inspections can be carried out on a regular basis and in significantly less time. During the planning stage, the feasibility of the inspection project is assessed on-site, where processes, workflows and requirements are identified. Specific test components are selected and appropriate diagnostic methods for the railway components are determined before the system is installed and commissioned.

Inspection modules for a variety of inspection and measurement tasks are available. Dirt accumulations on the train do not affect automated the automated inspection.

Examples for recorded potential damages or defects:


Inspection example: Wearing strip inspection

Inspection tasks:


Inspection example: Insulator inspection on the train roof
Bottom left: The color camera clearly reveals a part where the edge has broken off – Center right: 3D scan / line laser inspection – Bottom right: 3D rendering of broken edge

Different sensors monitor any train that passes the system for displaced components, connections or bolts that might have come lose due to vibrations that might affect clearance.


Inspection tasks:


Routine train inspections need to be performed on a regular basis. Trains need to be checked for worn parts where friction heat can lead to component deformations or represent a potential fire hazard.

The inspection robot independently moves along the train on an automated guided vehicle (AGV) and records the required images and data for every single car.


Our mobile inspection robot collects images and data in locations that cannot be covered by a stationary sensor portal.

It uses complex motion sequences to record images and data of difficult-to-access train components – the inspection of wheel truck brake linings is a good example.

Typically, the robot works alongside service personnel during train inspection. To ensure a safe human-machine cooperation, our system permanently monitors the robot's work space, placing particular emphasis on applicable standards and directives for collaborative and cooperative robotics. In addition to traditional scanners for automated guided vehicles (AGV), our solution also includes a safety-scanning feature at the robot's end-of-arm tooling to ensure that no people or obstructive contours are in the robot's range of motion.

Apart from vision sensors, the end-of-arm tooling system can include a variety of different sensors that are best suited for collecting the required data. All recorded data are transmitted to a central data analysis unit where they are analyzed using artificial intelligence.
