Unfortunately that official information is only correct in theory. Lighters and matches are only allowed (legal or not) if the TSA agents on duty when you pass through say they are. I have lost several allowed lighters and finger nail clippers in airports despite the published policies.

As for those stranded on the train - life is pretty much a come as you are event. I would probably go with life boat rules and try to help kids and women first. Given the very limited amount of stuff I have on me for my commute that wouldn't go very far but I'd feel better about helping out some kids even while I sat around shivering.

Even if I had the tools, I don't think I would consider a fire unless someone was seriously distressed (not just uncomfortable). Fire is a great tool but around the unwary it can help things go from bad to worse very quickly.
