Railways are a critical part of modern infrastructure, but maintaining them safely and efficiently is usually a big challenge. Traditional inspection methods often require on-site visits, manual checks, and quite a lot of time and cost. But today, AI-powered rail inspection systems are changing that.
These systems use video data, sensors, and machine learning to monitor railway infrastructure remotely – no site visits required. They help detect faults earlier, improve safety, and reduce the need for physical inspections.
In this article, we’ll be taking a look at three AI-powered rail inspection solutions: One Big Circle, SNC-Lavalin, and Wabtec Corporation.
What Are AI Rail Inspection Systems?
AI-powered rail inspection systems use technologies like cameras, sensors, and machine learning to monitor tracks, trains, and surrounding infrastructure.
They typically offer:
- Remote inspection using video data
- Automated fault detection
- Real-time monitoring
- Predictive maintenance insights
- Digital tools for planning and analysis
These systems help rail operators reduce downtime, improve safety, and make better decisions using data.

One Big Circle (AIVR Platform)
One Big Circle developed AIVR (Automated Intelligent Video Review), an AI-powered remote monitoring solution designed for remote railway monitoring using AI and video data.
Key Features
- Browser-based platform
AIVR is fully browser-based, meaning users can access it from anywhere without having to install software. This makes it very easy for teams to review rail data remotely.
- Large rail video data library
The platform includes over 500,000 miles of video footage, which allows users to inspect railway infrastructure without visiting the site.
- Remote inspection capabilities
AIVR also enables engineers to carry out inspections remotely. Reviewing just one hour of video footage can replace several hours of travel and on-site work.
- AI-powered fault detection
Machine learning models automatically identify issues such as hotspots, faults, and asset defects. This helps teams prioritize maintenance and reduce risks.
- Thermal and high-speed imaging
One Big Circle’s system also uses high-resolution and thermal cameras to capture more detailed track data, supporting advanced inspection and monitoring.
- Wide range of inspection tools
AIVR supports multiple use cases, including:
- Conductor rail inspection
- Track geometry analysis
- Railhead contamination monitoring
- Signal sighting
- Vegetation management
- Level crossing monitoring
- Real-time data and integration
Data is transmitted in real time using 4G/5G networks and can be integrated with other systems, giving teams a unified view of operations.
Pros
- Strong focus on remote inspection
- Large volume of rail video data
- AI-based issue detection
- Easy access through browser
- Supports many inspection use cases
Limitations
- Relies heavily on video-based data
SNC-Lavalin (Digital Rail Solutions)
SNC-Lavalin (now part of AtkinsRéalis branding) provides digital rail and infrastructure solutions that include AI-driven inspection and asset management tools.
Key Features
- Digital asset management
SNC-Lavalin offers systems that help rail operators monitor and manage infrastructure assets using digital tools and data.
- Use of AI and analytics
The company also applies data analytics and AI to improve maintenance planning and identify potential risks earlier.
- Integration with rail operations
Their solutions are designed to work alongside existing rail systems, supporting planning, maintenance, and operations.
- Focus on large-scale infrastructure
These tools are typically used on major rail networks, where managing large volumes of data and assets can be critical.
Pros
- Strong experience in rail infrastructure
- Focus on large-scale projects
- Combines engineering with digital tools
Limitations
- Less focused on a single dedicated inspection platform
- Solutions may be more complex and enterprise-oriented
Wabtec Corporation (Inspection & Monitoring Technologies)
Wabtec Corporation provides a range of rail inspection and monitoring technologies, including systems that use AI and sensors.
Key Features
- Automated inspection systems
Wabtec offers systems that monitor rail infrastructure and rolling stock using sensors and imaging technologies.
- AI-driven analytics
Their platforms also use AI to analyze data and detect issues such as component wear or faults.
- Wayside and onboard monitoring
Wabtec provides both trackside (wayside) and onboard inspection systems, offering broader coverage across rail operations.
- Predictive maintenance support
Wabtec’s system can help identify problems early, which allows operators to plan maintenance before failures occur.
Pros
- Wide range of rail technologies
- Combines hardware and software solutions
- Strong focus on predictive maintenance
Limitations
- Less centralized platform compared to AIVR
- May require multiple systems working together
Key Differences Between These Systems
Each solution takes a slightly different approach to AI-powered rail inspection:
- One Big Circle (AIVR) focuses on video-based remote inspection and easy access through a browser platform
- SNC-Lavalin focuses on broader digital infrastructure and asset management solutions
- Wabtec combines hardware and AI analytics for inspection across trains and tracks
Conclusion
AI-powered rail inspection systems are changing how railways are monitored and maintained.
One Big Circle stands out with its AIVR platform, offering strong remote inspection capabilities, a large video data library, and easy browser-based access.
SNC-Lavalin provides broader digital rail solutions, making it a good fit for large infrastructure projects.
And Wabtec Corporation offers a mix of hardware and AI-driven monitoring systems, ideal for predictive maintenance and full-system coverage.
Each solution has its strengths, and the best choice depends on the specific needs of the railway operator. However, all three show how AI is helping make railways safer, more efficient, and easier to manage.
