car/locomotive numbers, axle numbers and wheel positions. IEM responded by developing and installing the first machine visionbased wayside wheel profile measurement systems in 2006. This technology produced measurements of rim thickness, flange thickness, flange height, back-to-back measurements, and flange angle, which were all transmitted to a central server linking the measurements to the specific car, wheel and axle number.
and defects such as spalling and rim folloever. With ten years of experience developing, installing and refining the technology, IEM has now developed an instrumented tie box design which, by providing a single platform for multiple measurements and by “floating� with the rail, has proven to minimise maintenance and calibration issues.
These technologies are all integrated through the WISEtm (Wheel Inspection System Since the original wheel profile Environment). The WISE data measurement system, IEM has management capabilities transmit embarked on a path of developing defect data to system managers and adding new measurement so that wagons and locomotives components including wheel with identified defects or diameter, brake shoe condition, conditions approaching a defect disk brake conditions, sliding level can be automatically routed wheel detection, stuck brake to a service shop where the detection, thermal and acoustic problem can be fixed, avoiding detection of faulty bearings, flat costly unscheduled downtime in spot detection, out-of-round the field. wheel detection, bogey dynamics (hunting), dragging equipment WISE installations can be located detection and wheel flaw on main lines, in classification detection including surface cracks yards, and in shop environments.

By providing a comprehensive integrated family of inspection services all with common data links and operating system software, the WISE family provides efficiencies in the areas of data management, system integration, and system maintenance. While the maximum benefit is derived from the integrated system, customers always have the option of starting small and adding components over time as needs change and funding opportunities arise.
