The purpose of this study is to clear the derailment mechanism and effect of anti-derailing guard rail on large earthquakes because the Shinkansen train was derailed by the Mid Niigata Prefecture Earthquake in October 2004. At first, in 2005, we have designed the 1/5 scale vehicle-track model and excitation device and have introduced these devices in Komaki of JR-Central and until now we have conducted the 5000 cases of excitation experiments in order to complement the result of the full-scale bogie excitation test. As a result, we conclude that the derailment occurred in the excitation frequency range of 0.5-2.0Hz (full-scale corresponding value) is the rocking derailment and that the anti-derailing guard is effective for the rocking derailment.
