"Well, apparently kicking it isn't doing anything."

Because all Inigo is getting for his efforts here is a sore foot. And it doesn't even seem that the train noticed them, because it sure isn't opening the doors, nor is it giving absolutely any other sign that it actually knows they're out here.

"And I have absolutely no idea how else to grab its attention. If it doesn't even notice something hitting it, then what does it notice?" After all, Inigo sure would notice it if someone kicked him, thanks. Why can't the train do the same? How dumb is it?
