This is a Fast Travel/ Respawn station from currently Borderlands 2 and Borderlands The Pre-Sequel. One is orange for more of a prototype which is now more of the final. the yellow Fast travel just has a curved top instead of of more accurate flat top. The Fast Travel station in mainly used for Traveling to destinations without walking or driving, so you can just teleport to the place you want to go to, otherwise it is used for a check point and a place to respawn when your character Gets killed by an enemy. I hope you like it! Like It If You want to see more! Thanks Everyone!
