Helian, your's is not a better thought experiment. Yours is just a different thought experiment.

The first thought experiment though speaks to something completely different. Utility is not a factor in this. So the question remains... What prevents a person for pushing that button?
Better at least in that we're more likely to receive honest replies.
I disagree. Your thought experiment is about numbers that can survive and not so much about morality... except that by number crunching, we humans highlight our social context to which utility is applied. Empathy really doesn't play a significant role in this. If it did, then conflict would arise in the decision making. For example... Do I have a right to actively deny the autonomy of one man in order to save five who would be otherwise dead without my acting?
Compare the runaway train to this thought experiment which aims to highlight the lack of moral consideration in your thought experiment.
An otherwise healthy man is deemed brain dead and his organs if harvested could save the lives of five other men who will die without such intervention. The family of the brain dead man refuses to have the body harvested for religious reasons. Do we act anyway to harvest those organs and save the lives of five men? Utility alone would say yes. But utility ignores autonomy and it is autonomy that is the real moral consideration here.
So whilst it is that in situations of immediate emergency, utility serves us well to ensure the greatest number survive, in other matters it is the autonomy of others to which our moral considerations need to be applied.
So, what would prevent us from pressing the button in the initial thought experiment? One would hope that it is the right to autonomy that the person at risk of murder has.
