Three hundred and thirty-five "F" couplers removed from service during heavy repair of TTX cars were examined and measured. Selected couplers cast before March of 1970 and which had cracks, were tested at 0ousF and room temperature to determine the strength of the butt in pull. Metallurgical analysis of the selected couplers were made. Conclusions relating miles of service to expected strength are published.
