Wheel-rail force measurement is essential for validating rail vehicle running dynamics and ensuring safe operation. In this application note, TÜV SÜD Rail shows how imc MTP-NT-XS telemetry helps measure wheel-rail forces more efficiently during demanding on-track tests. The standardized, railway-proof housing solution is based on imc MTP-NT telemetry and enables fast installation on instrumented wheelsets without modifying the wheelset itself. Its modular design allows measurement modules to be exchanged quickly, reducing downtime during costly track tests. With robust metal housings, waterproof connectors, IP68 protection, and reliable wireless or inductive data transmission, imc MTP-NT-XS is designed for harsh railway environments, including high rotational speeds, dust, water, ballast impact, and winter conditions. The result is a flexible telemetry system that improves setup efficiency, serviceability, and system availability in rail vehicle validation.
