Data Summary Definitions

Data summary definitions provide detailed information on attributes that appear in individual data summaries, including open and close criteria. Each definition also includes indicators that aid railroads, car owners and others in making maintenance planning and repair decisions.

 

Data summary definitions currently available are:  

 

Acoustic Combined Data Summary: This data summary is used to identify internal wheel bearing defects before reaching an industry condemnable level for the purpose of preventative maintenance planning. The data summary is opened and updated from acoustic bearing detectors from two vendors: RailBAM® and TADS®.
