TBOGI-TR: Bogie Condition Monitor and Hunting Detector for transit and metro railways

WID’s TBOGI-TR system combines innovation and expertise to deliver improved wheel life, rail life, and maintenance resourcing.

Train operators

Are any wheels wearing out asymmetrically (thin flanges or hollowing)? Are any wheels wearing out too quickly, either during or at the end of their lifespan? If such conditions exist, then TBOGI can offer significant returns in terms of improved wheel life (case studies have shown up to 50% more wheel lifespan), but also less maintenance required as maintenance interventions can be targeted at the root cause defect(s), even if they are out of sight of any other monitoring, which stops repeat defect cycles. Using TBOGI data has also been shown to result in less fuel/energy consumption required for trains to operate.

Rail infrastructure owners

Does the rail exhibit any rolling contact fatigue, or any gauge corner wear, cracking or shelling, or material flow? If such conditions exist, then TBOGI can offer significant returns in terms of improved rail life (case studies have shown up to 50% more rail lifespan), but also less rail grinding required as each type of defect identified by TBOGI is responsible for specific types of rail wear, and railways can then prioritise interventions based on issues that are most prevalent in their network.

The TBOGI-TR System

Installed next to the tracks, TBOGI-TR is a laser-based system that measures an advanced array of geometry metrics for each wheelset and bogie, and their stability (hunting). With this data, TBOGI-TR enables railways to:

• Assess the in-service condition of wheels and bogies;
• Accurately identify defects, and trend their degradation; and
• Identify the components that need maintenance and gain unique insight into the causal issues that other monitoring approaches cannot see. This stops repeat wear cycles and saves significant resources.

TBOGI-TR is proven to perform in locations with tight clearance envelopes. TBOGI works with any wheelset diameters. TBOGI measurements are immune to changes in weather, train configuration, and rail lubrication conditions. Measurements are accurate for train passes between 1 to 300 km/h. The system complies with all necessary EN, IEC, CE, and FCC certification standards.

WID has helped railways enjoy significant savings and improved efficiency for 25 years.
