The Main Elevator was found in the Main Sector of the BOTTLE SHIP. It was one elevator with three doors, connecting to the Biosphere, Cryosphere and Pyrosphere. The Biologic Space Laboratories research station in Metroid Fusion also had a Main Elevator leading to numbered sectors.
Following Samus's battle with Ridley, she returns to the Main Sector via this elevator, and spots a lone member of the 07th Platoon. She follows him to the Biosphere, but loses track of him once she reaches the Bioweapon Research Center.
