Since 2007, Bolliger & Mabillard have used floorless trains on their Dive Coasters, such as Griffon and SheiKra.

[1] In 1999, the world's first Floorless Coaster opened at Six Flags Great Adventure as Medusa.

B&M has built 13 Floorless Coasters from the ground up, with Dominator at Kings Dominion being the only one relocated to another park.

Once all the over-the-shoulder restraints are locked, the floor separates into several pieces and retracts underneath the station.

When the train returns to the station, the floor is brought back up and the gate is closed for the next group of riders to load and unload.
