Rail Profile Measurement


Rail Wear Measurement

KLD Labs offers both automated and portable measurement systems for assessing the rail profile and rail wear conditions. The rail profile output is utilized for for asset optimization, condition based maintenance, wheel rail interface analysis including equivalent conicity and contact patch studies.

Automated

KLD Labs’ ORIAN (Optical Rail Inspection and ANalysis) family of automated high speed rail measurement systems incorporate the latest laser and imaging technology to provide immediate feedback on the rail profile and rail wear condition while traveling at track speeds. The video cameras capture full cross-sectional rail profiles from the base/web fillet area up to the top-of-rail surface to allow comprehensive and accurate rail measurements.

The ORIAN sensor heads are mounted beneath a railway vehicle. The central computer and peripherals are housed inside the vehicle. As the vehicle travels down the track, a laser system illuminates each rail as a high-resolution video camera records the rail profile for processing and storage on the central computer. The computer then shows exactly how much wear the rail has suffered, as well as the overall condition of the track structure. This information is stored internally and is then transferred off the vehicle to enable data playback and analysis.

The ORIAN™ rail profile measurement systems available capabilities include identifying rail types, measuring rail height, vertical wear, rail width, lateral wear, field/gauge metal flow-lip, rail inclination, track gauge, rail cant (rail inclination) and joint bar/fish plate presence as well as other customer defined measurements.  For reasons of performance, reliability and customer service it has become the preferred rail measurement for the largest rail service providers in the world.

Portable

For portable rail measurement the MiniProf Rail instrument is an easy to use, lightweight and handheld tool for monitoring cross sectional profiles of the rail. It is attached magnetically to the rail and references the adjacent rail for gauge measurement and crosslevel. The instrument can be used on many different rail sections and is easily transported. The instruments are normally used with a laptop or rugged handheld computer for data collection. For more information on the MiniProf: http://www.greenwood.dk/miniprofrail.php
