Abstract
Authors made an experimental event recorded which can record not only the behavior of a train, but also accurately identify the sites where wheel slides and spins occur. The recorder was installed on a JR Ltd Express EMU operated on conventional lines. They analyzed the date piled up in the recorded, and found several wayside factors which cause the wheel slides. The wheel slide occurrence rate par a 1000 km train running distance was discussed under various weather conditions. Moreover, the results of the investigation were also discussed on the wheel slide occurrence rate in a snow bound area and the relationship between a snow weather condition and wheel slide occurrence rate.
