TBOGI-TR
What is TBOGI-TR?
Intelligent Bogie Monitoring for Urban Rail Networks
TBOGI-TR is a compact, laser-based bogie geometry monitoring system purpose-built for metro and passenger operations. Installed trackside, it captures critical data on bogie condition and wear rate—transforming maintenance from reactive to predictive.
Measured Metrics:
- Tracking Position (TP)
- Angle of Attack (AoA)
- Hunting (Instability)
- Tracking Error
- Rotation
- Shift
- Inter-Axle Misalignment
How It Works:
Using advanced optics, TBOGI-TR accurately measures bogie alignment—even in tight urban corridors, tunnels, or elevated guideways. With minimal installation requirements and high data reliability, it ensures railways can detect issues before they disrupt service.
Above Rail – Wheels, Bogies & Rolling Stock
Longer Wheel Life, Less Noise, and Smarter Interventions
In metro systems, reliability and quiet operation are everything. TBOGI-TR identifies geometry issues like underlying accelerated flange wear, tread wear, or bogie instability before they result in noise complaints, failures, or unplanned downtime. It delivers actionable insights without relying on force-based systems or image recognition—making TBOGI-TR data reliable, repeatable, and able to identify underlying defects that are otherwise out-of-sight of man or machine.
Key Benefits:
- Extend wheelset life by up to 2×
- Reduce wheel squeal by identifying causal wheelsets
- Fewer unplanned maintenance events
- Pinpoint hard-to-see causes like loose side bearings or suspension asymmetry
- Improve energy efficiency by isolating wheelsets with elevated rolling resistance
Short-Term Gains:
- Less time in the workshop
- Better ride quality
- Enhanced fleet availability
Long-Term Gains:
- Fewer repeat interventions
- Lower total lifecycle cost of wheelsets
- Predictive maintenance mindset
- Lower energy costs
Below Rail – Rail Life & Track Safety
Prevent RCF and Disruptions, Particularly Through Curves and Turnouts
Passenger railways can’t afford track damage that causes speed restrictions or shutdowns, or indeed the track time for regular rail grinding. TBOGI-TR tracks how each bogie behaves and highlights the ones causing RCF—such as flaking, gauge-corner cracking, or head checking. This allows timely, targeted responses that preserves the rail.
Key Benefits:
- 20–50% less RCF and grinding overhead
- Avoid unplanned rail maintenance by identifying root causes early
- Protect turnouts and crossings from geometry-induced damage
- Improve rider experience by reducing noise and vibration
Short-Term Gains:
- Fewer disruptions and speed restrictions
- Reduced rail maintenance workload
Long-Term Gains:
- Extended rail life
- Safer, smoother service across the network
