REPORT ON THE CHARACTERISTICS OF STEELS AT LOW TEMPERATURES--COUPLER INVESTIGATION

The report discusses problems in finding a basis for coupler failures between geographic areas. The parameter for comparison was the number of failures per freight car miles travelled. Conclusions are that more couplers fail during cold than hot months. The critical temperature for failure occurs a few degrees below freezing.
