It is said that Japan is a land of earthquakes and to prevent a run risk of train from earthquakes is of significance for the safety of running trains. An alarm system, called "YUREDASU" was developed and utilized for prevention of derailments. This system can provide an alarm to running trains and stop the operation just after detection of the primary wave of an earthquake before coming the following secondary wave. However, it is known that in an earthquake which occurs at shallow focal center or at short a distance from focal center, the duration between the P-wave and S-wave becomes shorter and it is desirable to equip an auxiliary system to prevent the running trains from derailment till the trains have stopped completely. Thus in this study a new concept of such an auxiliary system is proposed and an conceptual design of the equipment to prevent derailments is developed. Then an excitation test is carried out using a scaled model of the system to verify the effectiveness of the proposed system.
