The Loram Rail Inspection Vehicle

The Loram Rail Inspection Vehicle (RIV) is equipped with a track profile measurement and reporting package to track quality assurance and planning needs. This package is a proven system in use in North America and Australia, and consists of several integrated components including state-of-the art optical transverse profile measurement systems, proprietary position locator system based on differential global positioning system (DGPS), proprietary profile analysis, grind quality control software, and proprietary data viewing and reporting software.


The Loram Rail Inspection Vehicle (RIV) ensures the most efficient application of the rail grinder to the rail conditions. A state-of-the-art profile measurement system automatically determines optimal grind angles and maximum speeds to ensure the right profile will be achieved. Data collected is mapped to track location to positively match the plan when applying the rail grinder. Quality can be verified with a follow-up inspection after the rail is ground.
