We conducted full scale experiment to verify the function of anti-derailing guard rails to prevent the derailments due to large earthquakes. The experiment was arranged to simulate the vehicle/track conditions of Tokaido Shinkansen by using the bolsterless bogie and the track materials both presently in use for Tokaido Shinkansen. Large excitations enough to derail the test vehicle were given in order to make clear the function and effect of anti-derailing guard rails. We obtained the following results. (1) The guard rails worked effectively to prevent rocking derailment by holding the lateral motion of derailing wheel-set. (2) Effective work of guard rails was verified in total 34 test cases of sine wave excitations of the frequency range from 1.1Hz to 1.5Hz. (3) Also effective work of guard rails was verified by using the excitation of Tokai Earthquake. (4) Compared with horizontal ground motion, vertical ground motion of earthquake had smaller influence on the derailment mechanism.
