Once a nuclear coolant replenishment and service station, it now sits abandoned and uninhabited.
The Quincy filling station is a Red Rocket located just outside of town, between the main entrance and Quincy Quarries. The station's layout is identical to that of other large Red Rocket gas stations, with the exception of Gunners milling around the exterior. An orange Cherry Bomb sits in front near a power armor station. At the front door of the station beside the Cherry Bomb there is a railroad safe house sign.
This Red Rocket station appears only in Fallout 4.
