However, in the 'Toki 325 train' case, the train could not stop before having been damaged, although the brake was applied immediately after a preliminary tremor (an earthquake wave) was detected, because the earthquake occurred just under the train.
しかし、「とき325号」のケースでは通過地点でほぼ直下型の地震であったため、初期微動（地震波）検知後にブレーキをかけたものの地震の被害を受ける前に停車する事はできなかった。
