TinkerTurf Sci-Fi - Cargo Containers Series 4

Even though they are essentially super-sized crates, do not be afeard. Scattering a few of these sturdy rectangular objects around your MagLev yard will make it feel more visually 'complete', and serve to block out large areas for line-of-sight. Or funnel ground movement into choke points ripe for a massacre. Okay, be afeard. Containers are like super-sized LEGO bricks of death.

And, they're terrific for kit-bashing! Cut a couple linear viewports into one, and you've got yourself a bunker. Place two end-to-end, and they're a mobile-deploy field laboratory. Pile them up and connect them with stairs and walkways from the Elevations set, and they're a residential Stack from a dystopian future.
