This is a WIP model I've been playing around with for a while, Its a Terran Bullet Monorail with 2 deck's.
Its an Automated vehicle so the 'cockpit' is just a viewing area for passangers. The only active Crew on the Bullet Train would be the Trolley Girls and a Technician.
The train is operated by DANA, Gaia station's central AI core. The Monorail track is completely straight from one end of the station to the other so the train doesn't need to bend at all.
