What is it about?
Railway track defects can lead to serious safety risks if they are not detected early. This study investigates how advanced artificial intelligence can automatically identify ten different types of rail defects using images collected from real railway tracks in India. It compares three state-of-the-art AI models (YOLOv11, YOLO-NAS, and Roboflow 3.0) and introduces a targeted data augmentation strategy to overcome class imbalance, improving the detection of rare but safety-critical defects. The results show that AI can deliver fast, accurate, and practical railway inspections, supporting safer, more reliable, and cost-effective maintenance.

Why is it important?
Railway track defects are a major cause of infrastructure failures and can lead to accidents, service disruptions, and high maintenance costs if not detected early. Traditional inspection methods are time-consuming and may miss small or rare defects. This research demonstrates that advanced AI can improve the speed, accuracy, and reliability of railway inspections, enabling earlier detection of multiple defect types and supporting safer, more efficient, and more cost-effective railway maintenance.
Perspectives
This research demonstrates the potential of AI to transform railway track inspection by making defect detection faster, more accurate, and more consistent. Future work will focus on validating the models across different railway networks and environmental conditions, integrating vision-based AI with non-destructive testing techniques, and developing lightweight real-time systems for continuous railway infrastructure monitoring. These advances could further improve railway safety, reduce maintenance costs, and support smarter, more reliable transportation networks.
