I doubt its that Cedar Fair can't afford to design a new station, or else why would they be shelling out a few million dollars for the coaster?
All three are the same type of coaster, made by the same manufacturer, same number of trains, Talon and Silver Bullet have same number of cars and they are all under the Cedar Fair umbrella. It seems logical to me that they are reusing the station designs with only minor alterations, much cheaper than designing 3 seperate stations.
