Sergeant Jeffords: We're building this for kids! You really think they're gonna enjoy your brown rectangle of dirt with one little house?
Captain Holt: Excuse me, this is an accurate facsimile of a mid-sized switching yard. And it isn't a "little house." It's a work shed where the yardmen get their OSHA-mandated eight hours of rest between shifts. So, yeah, I think the kids are gonna love it.
