This test measures dynamic forces between wheels and rails during actual on-track operation to evaluate vehicle stability, safety, and track loading characteristics. The test uses instrumented wheelsets and track-mounted sensors to quantify vertical, lateral, and longitudinal forces under various speeds and track conditions. Understanding wheel-rail dynamics is essential for preventing derailment, ensuring passenger safety, and predicting track maintenance requirements. Rolling stock manufacturers, railway operators, and infrastructure managers require this testing for vehicle certification and performance validation. ISO 17025 accreditation guarantees measurement accuracy, proper calibration, and adherence to international testing protocols critical for safe railway system operation.
