The System

TBOGI-TR provides transit and metro railways with a unique method for monitoring the condition of wheelsets and bogies to know when – and why – the costliest issues are emerging.

TBOGI-TR is a laser-based system that measures an advanced array of geometry metrics for each wheelset and bogie, to assess their in-service condition. This is a cornerstone of an efficient wheel-rail interface, and a cost-effective railway.

TBOGI-TR can also measure bogie instability (hunting) as an optional extension. It does so accurately, and in physical Standard Units (millimetres) rather than a meaningless index.
TBOGI-TR identifies both subtle and major defects, and then points maintenance at the causal component(s) that may be out of sight.

Identifying causality means that targeted action can be taken, and the cycle of repeat maintenance can be broken. Identifying the underlying causes breaks the most damaging wear cycles, both for rolling stock and rail infrastructure.

The System’s Purpose

TBOGI-TR systems have a proven history of increasing the lifespan of wheels and bogie components, increasing the lifespan of rail infrastructure, improving fuel/energy efficiency, and reducing risk:
Railways using TBOGI-TR report significant increases in the lifespan of wheels and other bogie components (bearings, brakes, suspension, etc.). By using TBOGI-TR data to reduce the wheel wear rate, other bogie components are subsequently under significantly less stress.

TBOGI-TR identifies defects that compromise the wheel-rail interface. This underlies accelerated wear and RCF to the rail as well. By addressing the severe TBOGI-TR defects, railways can significantly reduce the wear rate of the rail, and thereby increase the life of the rails with less grinding needed.

TBOGI-TR identifies which bogies are experiencing much higher rolling resistance. Addressing these specific bogies results in corresponding fuel/energy savings. Railways using TBOGI-TR have significantly reduced their derailment risk. TBOGI-TR identifies many risks that not identified by other monitoring systems. Also, prior to derailment, high-risk defects inflict major RCF and wear at the wheel-rail interface, so the benefits of intervention are two-fold.

System Installation

TBOGI-TR systems are wayside technology, installed next to the track, outside the clearance envelope. They are installed at trunk points of a network (on straight track), where the system can monitor traffic going at speed.

TBOGI-TR is designed to be installed in locations specific to transit/metro railways, such as tunnels, metropolitan areas, and multiple-track main lines.

TBOGI-TR installations do not interfere with track maintenance and can gather measurements at any trains passing speed up to 300 km/h. Measurements are immune to changes in weather, train configuration, and rail lubrication conditions.
