I feel so sorry for the passengers and victims onboard. This would be my worst fear being on a train or plain having no control or way out of such a big accident. They must have been so afraid once the train started rocking back and forth. I wonder what actually caused this horrible accident in the first place. They said that a similar one happened earlier so it must be connected. A full investigation should be done to find the cause and fix it. The train should be shut down to avoid loss of life while it is investigated and corrected. It seems to be a totally avoidable way to lose a life and needs to have more security measures put into place.
