I say travel well prepaired,, I don't trust the train, or plain companies to tend to my needs I expect me to be there for me and those with me. YES I over pack!!
I think that most of the population at large are aways expecting someone to tend to them and take care of there needs. Those of us here on this site think difrently, we see this news report and think, "how can I prevent that happening to me," or, "what would I have done in that situation," the average person who sees that thinks, "what a tragidy!"
I look at that as a reson to carry playing cards in my Man bag now so that I could at least play some card games with those around me and get to know people. Heck, you could make friends for life during that ordeal.
