Some cover, as Lapine sees before the full designs go up (a tradition for half the precinct according to Andy), will be real. Might not be the easiest to tell once everything's up and running, but right now there's one 'full room' to memorize if wanted.<br/><br/>The interior, once projected, looks a little more restaurant than rail car. Not that anyone's an expert on old railroad car interiors, but it has that general vibe. Perhaps it's a cheap car? There's a little bit before the exercise is supposed to begin, to simulate being a surprise event, so everyone gets to talk a little and hope that the gunshot and alarm sounds don't interrupt them.
