Roller Coaster DataBase (RCDB) is an online database for information about roller coasters and amusement parks. It includes pages for over 5,000 roller coasters and over 2,000 amusement parks. The pages contain most major statistics and photos, but do not include other facts or histories. RCDB also does not log rumors until an official press release. A roller coaster will only appear on the site once the track pieces appear in the park.
