Instrumented wheelsets are railway wheelsets that have been instrumented and calibrated so that they are capable of accurately measuring the dynamic contact forces between the wheel and rail.

Typically, they are capable of measuring these forces in the vertical and lateral direction. SNC-Lavalin’s IWT4 technology can also measure forces in the longitudinal direction.

This video shows how our innovative IWT4 technology can brings benefits to your business.
