The Propulsion Systems station on the Enterprise-D
Propulsion Systems was one of the console stations on the bridges of Starfleet starships, used to control and monitor the various propulsion systems aboard ship.
On Excelsior-class starships such as the USS Enterprise-B, the station encompassed a large section of the port side of the bridge. (Star Trek Generations)
On Galaxy-class starships such as the USS Enterprise-D, it stood center of the rear bridge console suite, between the Science II and Emergency Manual Override stations. (TNG: "Encounter at Farpoint", "The Naked Now").
By 2365, it was replaced by a Mission Ops station. (TNG Season 2)
