Standardization of product in any industry is of paramount importance in promoting management efficiency. This is especially true of rolling stock parts. In other words, if the cost of production is to be cut down and the method of maintenance work rationalized, it would be imperative to minimize the number of parts and direct every effort toward that end. The JNR uses about 80 kinds of cast-iron brake shoes for its rolling stock, and annually produces as much as 50,000 tons of them (Ref. Table 1). This enormity in diversity not only is a great deterrent to our efforts to rationalize the casting operations through mechanization, but also involves a number of operational disadvantages. To do away with these disadvantages, the research and development committee for rolling stock has conducted a detailed study of its past findings and worked out a plan for the standardization of brake shoes for JNR.
