Transport Station Four of Pinyumb was a specific place found in the capital city of Pinyumb on the planet of Sullust. This station utilized a cargo lift that began on its higher floors to move people from the cavern that held Pinyumb up to the planet's surface. During 3 ABY, Thara Nyende, a stormtrooper, was working in the security office at Pinyumb Transport Station Four and had taken off her helmet during her shift. After the CR90 corvette Thunderstrike got to Sullust to pick up the Rebel Alliance's 61st Mobile Infantry, she was called to the upper levels, and she used the cargo lift to reach the surface and witness the corvette's destruction.
The 2015 novel Battlefront: Twilight Company by Alexander Freed featured Pinyumb Transport Station Four.
