Descripition of what I wondered

I would like to write down my experience and what I have been wondering through it. When I was caught in a train accident on Saikyo-Line, accompanying my friends, on our way to Higashi-Koshigaya-Lake Town, a big shopping centre, I first wondred why the train had stopped. Looking at the landscape out of the window of the train, there were no places on which to land. Soon, I heard the announcement made that the train had been rendered due to make a sudden braking due to having run over a person. But fortunately, it was not our train but another train up to Shinjuku Station that had run over him. Ours was not into but from Shinjuku Station. As soon as the announcement was made, everyone around me started to finger his or her mobile phone and complain. I understand it.But is it the usual case in Tokyo that the death on the railroad is treated that way because it is the death of only one person? Also I cannot understand why no one did not recognise the person who had killed himself. If someone had been the shoulder for him to rely on, he would have known better than to commit suicide.
