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 LaMarcus Thompson operated Coney Island's first roller coaster. The roller coaster was located on West 10th Street -- the street that today separates Astroland from the Cyclone.
