I'm not sure how those two questions are related, but Batman's very knowledgeable in pretty much all sciences, and extremely technologically talented, so I don't see how he could not stop a runaway monorail.
Only if he could find an anchor of some sort.
No he's not, and yes he could
He employs scientists. He’s just a billionaire pretending to have skills because he owns the people that do.
Sound familiar?
I wouldn't be too surprised if Musk and Bezos dressed up to beat up mentally ill people at night.
How much prep time does the monorail get?
