Welcome to Wayside Inspection Devices
Proven Technology. Smarter Railways.
At Wayside Inspection Devices (WID), we pioneer monitoring systems that help railways work smarter, safer, and more cost-effectively. Our flagship TBOGI technology gives railways the clarity to realize longer asset lifespans and improved cost efficiencies.
Smarter Insights for Stronger Performance
Our advanced laser-based TBOGI systems measure the complex behavior of wheelsets and bogies as they pass, without disrupting operations. From freight to metro networks, TBOGI delivers precision insights that translate into real-world advantages:
- Longer wheel and rail life through early defect detection
- Lower maintenance costs by identifying root causes, not just symptoms
- Improved safety and reliability with predictive alerts and clear diagnostics
- Reduced energy and fuel use by spotting rolling stock with elevated rolling resistance
Built on Experience
With over 30 years in the industry and installations across five continents, WID has earned a global reputation for accuracy, dependability, and innovation. Our systems are trusted by railways around the world to keep assets in top condition and reduce operational risk.
