Combines failure data from two sources with fleet population data to obtain a relative failure index which is a measure of the relative failure rates among the coupler and knuckle components currently in freight service on american railroads. Also, includes statistics from the AAR mechanized car repair billing exchange system for couplers and knuckle components currently in freight service on American Railroads. Also, includes statistics from the AAR mechanized car repair billing exchange system for couplers and knuckles removed from service during an eighteen month period.
