Amtrak Philadelphia train crashed at May 12. 8 people were died and more than 200 people were injured. At that time, the train was at twice the speed limit, and it kept increasing speed immediately in front of a curve. Moreover, the rail has became too old to use. In my opinion, the contempt of safety led this accident. Publick transportations must be the existanse of safety for users. In Japan, such accident is incredible. I hope it remains so.
