- "Why do we have to travel by subtram? Wouldn't it be easier just to land at our destination?"
"You'd think so. The atmosphere of our planet is completely pressurized, leaving all aerial travel impossible. If we attempted to land on the planet's surface, our ship would immediately implode."
"Subtram it is, then."
- ―Boba Fett and Major Rigosso
The subtram were repulsorcraft trains utilized on the subterranean planet Quarzite. On Quarzite, the subtrams flew through suspended hoops that formed an underground network linking the fortresses of the planet's dominant species, the Belugans. Coruscant also had a subtram system.
