This sounds kind of crazy, and really dangerous. If you are not exaggerating when you say that it would have hit you if LCM hadn't helped you up and the train driver hadn't seen you - there's something not right about this, you should not have been cutting it so fine with the train coming?? And why did you trip? Do you have mobility issues? If you do (for example, a friend of mine has just had surgery to have her wonky hip aligned, and she's only in her twenties) I assume LCM knows about them and should be not rushing across railway tracks?

It sounds like you both got a hell of a fright. I would worry that if things like this happen again, LCM will wonder if you are unconsciously engineering unsafe situations for her to rescue you from?
