This test was continued up to the running distance nearly equal to the one until truck overhauling. From the data of wheel shape, the wear characteristics were analyzed, and its quantitative effects to the running vibrations were researched. As the result, following matters were made clear. (1) During the running distance until truck overhauling, the Riding Quality Level of lateral vibration grows 2\uff5e3 dB, because of the increased play between the flange and rail which is caused by the flange wear. (2) In case of the tested truck, that is the same type with one of commercial trains, the tread wear does not affect much to the running vibration. And it is indicated as one cause that the effective conicity \u03b3_e differs little from the design value of 1/40 by the moving of contact point between the tread and rail.",
