WIM – Weigh-in-Motion for Railways
Axle load and load distribution monitoring
Weigh-in-Motion (WIM) systems measure the vertical forces generated by passing vehicles directly during operation and convert them into reliable information on axle loads, wagon weights, total train weight, and load distribution. This enables the early detection of overloading, asymmetrical loading, and critical load conditions.
Why WIM - Weigh in Motion?
Overloaded or unevenly loaded rail vehicles increase the stress on the track, track infrastructure, and structures. They also affect vehicle dynamics, wear and tear, maintenance costs, and, in extreme cases, operational safety. Weigh-in-Motion (WIM) provides transparency through automated, reproducible measurements – without disrupting normal rail operations.
Application areas
Axle load monitoring during operation
Detection of overloading and load imbalances
Monitoring of wagon weight and total train weight
Support for fleet management and maintenance planning
Reliable load data for bridge and infrastructure stress analysis
Integration into Wayside Condition Monitoring and asset management
Advantages
Dynamic load measurement without stopping the train
Measurement of axle loads, wheel loads, wagon weights, and total train weight
Detection of longitudinal and lateral load asymmetries
Early warnings when when limit values are exceeded
Seamless integration with additional wayside monitoring systems
Suitable for freight transport, mixed-traffic networks, and selected passenger transport applications
