Rail surface irregularities of the order of microns (0.001mm) in amplitude are important in the generation of wheel/rail rolling noise and vibrations. The O-RCA is a compact and easy to install high precision contactless measuring device to obtain a continuous longitudinal measurement of irregularities such as corrugations on the rail head. The O-RCA can be fitted to trains, hi-rail vehicles and wagons and can be used on various track gauges (standard, narrow or wide gauge).

TECHNOLOGY FROM THE LEADERS IN RAIL MEASUREMENT SYSTEMS

The O-RCA gives reliable measurement results of irregularities on the rail head over the full wavelength range as per EN13231-2:2020 and earlier versions of this standard. The user-friendly reporting software allows for superimposing measuring runs, setting required tolerance limits and showing the % exceedances.
