Presents the initial 18 months of yoke removal data (for foreign cars only) reported to the newly established AAR Mechanized Car Repair Billing Exchange System in Washington, D. C. This computerized system lists the reason the yoke was removed under eight code numbers which interpreted mean, worn out, broken, missing, bent, bent beyond repair, obsolete, account other repairs, and removed in good condition. There were a total of 19,647 yoke removals reported in the initial 18 months. The number of reporting railroads (11 total) participating in the system at the end of the first 18 months accounted for a little over half of the freight car ownership in 1972 and therefore perhaps about half of the yokes removed from foreign cars by railroads (foreign cars are cars not owned by the reporting railroad). Considering this condition combined with other factors it seems reasonable to multiply the total removals reported to the AAR Billing Exchange by about 6 to obtain the total removals by the industry for the entire current service fleet of freight cars.
