The Tube Rats

A large and loosely-connected “family” of vagrant kids, mostly in their teens or early twenties, who hang out in unsensored areas underground and free-ride in the wakes of maglev trains, both for transportation and as a lifestyle. The rigs used to accomplish this feat are called Plunger Suits, and they are as dangerous as they are illegal.

K8T is one of the more well-known Tube Rats.

Excerpt:"Their nest was a series of large residential containers, each wedged down beneath the crosshatch of vactrain intersections. Tucked in a physical industrial blind spot, a place no one in the city ever looked. Here they had access to city system and a sanctuary that neither muncies nor maintenance crew bothered with.  If the heat came down, they could move the containers.  One of them had legal paperwork capable of standing up in court.  The container K8T resided in was old and defunct, the type of model thrown away by wealthy fashionistas every year.  The crew had “borrowed” an antigrav rig from a construction site and moved the whole thing out of a scrapyard in the middle of the night.  They hardlined into city system and blinded intersection sensors to look around their blind spots, keeping them off-grid."
