Content.
Each roller coaster entry includes any of the following information for the ride: current amusement park location, type, status (existing, standing but not operating (SBNO), defunct), opening date, make/model, cost, capacity, length, height, drop, number of inversions, speed, duration, maximum vertical angle, trains, and special notes. Entries may also feature reader-contributed photos and/or press releases.
The site also categorizes the rides into special orders, including a list of the tallest coasters, a list of the fastest coasters, a list of the most inversions on a coaster, a list of the parks with the most inversions, etc., each sortable by steel, wooden, or both. Each roller coaster entry links back to a page which lists all of that park's roller coasters, past and present, and includes a brief history and any links to fan web pages saluting the park.
