I get what you're saying, based on the idea that the BBS works in a similar fashion to an airplane. There have indeed been records of people surviving falls from aircraft at much higher altitudes than 400 feet, so the BBS sporting stuff like emergency exits and those inflatable slides aren't out of the question at all...
However, I think that placing hammers next to the emergency exits so that survivors can break through the windows is a bit of a stretch, from a structural point of view at the very least, considering that most subways use multiple layers of glass on the cars' windows to prevent the outside elements (cold, heat, etc.) from leaking inside. No doubt the spider thing could bust through these windows, but I think that even Lock would have a hard time busting one. (Just my opinion, though. I could be very wrong.)
Aight, first off, I'm asking the GM, Gummy. Second, even if he can't shatter the window, there should be some form of emergency exit he could force open given that not installing something like that would probably violate all kinds of safety rules.
The hammer question was a bit of a dumb idea, but it's based on how public transport in my are has hammers with a special tip that can shatter the windows with some mild force put behind it, including some of the older trains. Granted, those windows were also made to break if specifically hit with those hammers because of the way the glass is made.
Should at least be a hatch or something that connects to the outside, if nothing else.
