This park entry only contains one of the roller coasters of Coney Island. Coney Island has always been made up of many amusement vendors. Then name Coney Island referrers to an area, not a single park. For example the classic Coney Island Cyclone is located at "Astroland" and the famous Wonder Wheel is located at "Deno's Wonder Wheel Amusement Park". Currently these are the only two named parks, while the rest of the rides operate under the umbrella of the Coney Island name.
The entry is for the area on which George Moran operated the Thunderbolt. George was an independent ride operator and never operated the rides under any specific park name.
