There are pretty suitable explanations why the guests can't be harmed or how do the hosts work. Though, there is still something I can not figure out.
When the new two guests come into the Westworld in the second episode of the first series, they get to the park by an elevator that leads inside a moving train. How is this possible?
Is the Westworld park a real thing within the TV show? How else could they have gotten inside the moving train?
