Wheelset and track profile for train and rail

Train wheelsets and rail infrastructure are typical wear parts, and have significant effects on passenger comfort and safety as well as noise and ride. Profiles of wheels, brake discs, rails and switches are therefore regulated by recurring measurement operations in demanding operating conditions. The challenge lies in the efficient generation of valid measurement data for the entire wheel-rail system. Efficient wheelset profile measurement can drive timely maintenance actions and help minimise train down time, as well as ensuring a smooth and safe journey for rail passengers.

Hexagon’s NEXTSENSE CALIPRI C42 and CALIPRI Prime optical profile measuring instruments meet the specific demands of the railway industry by delivering accurate and reproducible results, independent of operator influence. These specialised profile measurement devices are widely used for wheel wear inspection, brake disc measurement, wheel back-to-back and diameter measurement and rail wear inspection.
