In the works of our Government Kailwny Department, there has been spent much cost for repairing springs, and many improvements have been made in this field, but it seems that there are still more things to be considered. To keep the springs in the better conditions means the safety of the railway rolling stocks, and so we must exert ourselves to investigate the conditions of the springs which are in work on the rolling stocks at present. For this reason, decrease of thickness, depth of decarburization and carbon content of the spring leaves used in our goods cars were studied, and we found that a spring leaf which contain less than 0.6% of carbon and can not be hardened in oil quenching, amounts 30% of all spring leaves, and a spring leaf which thickness is decreased more than 10%, amounts 5% of all spring leaves, but the latter will be contained in the former. From this result, we obtained an improving rule to keep the springs in the better conditions.
