Next-generation Rail Weigh In Motion system

Improve the safety and cost-effectiveness of your freight transport business using real-time data relating to weight and uneven weight distribution.

Smart management of rolling stock and infrastructure with one system: the new Rail Weigh In Motion (WIM) system from Kistler provides accurate and reliable weight measurements from wheel load to train weight – and, based on integrated algorithms, a full range of additional traffic and train condition data.

Thanks to scientific field research and physical modeling, the new system makes use of an optimized sensor layout that combines high precision with easy installation – only minimal track closures are required, or none at all. As well as measuring weight-related parameters, Rail WIM from Kistler collects and calculates data about rail vehicle safety and track usage.

Multi-purpose comprehensive WIM solution

Applications include Safety in Operation (derailment prevention, verification of train weight, spacing between trains, speed monitoring and bridge protection, etc.), Preventive Maintenance (infrastructure wear and tear, rolling stock condition monitoring) and Compliance (overload, wheel defects, incorrect weight declaration and incorrect train length).

Rail Weigh In Motion from Kistler includes these functions:

Measurement of vehicle and train weight
Vehicle identification, classification and statistics
Accurate speed measurement
Detection of unbalanced vehicle loading
Detection of axle parallelism
Condition monitoring of wheels and bogies (flat spots, spring defects, axle/wheel distance)
Self-monitoring with frequently used and known vehicles

Benefits

Excellent system accuracy at operational speed, based on piezoelectric force measurement
Outstanding long-term and temperature stability
Additional functionalities, e.g. flat spot detection
Simple and fast installation
Site assessment and adaptive system layout to reduce influence of vehicle dynamics
Generation of comprehensive train reports and flexible data protocols
Negligible ageing effects and minimal maintenance effort
