ABSTRACT: The Wear Data Collection Program was a field testing study associated with the Truck Design Optimization Project in which test trucks in unit coal train service were monitored for wear in an effort to develop comparative wear performance data. Seven truck types (one car set of each type) including both standard three-piece trucks in common use in the industry and premium trucks which incorporate design features such as steering in curves were monitored and periodically disassembled at which time a large number of mechanical measurements were made at points which were considered to be potential wear points. This report reviews and evaluates the measurements which were taken and describes the forms in which this data is now available. In addition, recommendations are made both for reducing the number of measurements and for simplifying the problem of storage and retrieval of the data by reducing the number of data points.
