Top Thrill Dragster is a steel accelerator roller coaster built by Intamin at Cedar Point in Sandusky, Ohio, United States. It was the sixteenth roller coaster built at the park since the Blue Streak in 1964. When built in 2003, it was the first full circuit roller coaster to exceed 400 feet (120 m) in height, and was the tallest roller coaster in the world, before being surpassed by Kingda Ka in May 2005. Top Thrill Dragster, along with Kingda Ka, are the only strata coasters in existence. It was the second hydraulically launched roller coaster built by Intamin, following Xcelerator at Knott’s Berry Farm. The tagline for Top Thrill Dragster is “Race for the Sky”.
Occasionally, a train is launched with not enough speed to clear the crest. This typically happens in cool, wet, or breezy weather, or when the wind is working against it. In these conditions, the launch often does not provide it with enough speed to climb over the hill, which causes it to stop short of the top, and roll back down the hill in reverse, hence the term “rollback”. The launch track is equipped with retractable magnetic braking fins which are raised after the train is launched in order to slow one that did not crest the hill.
On very rare occasions a combination of the weight distribution of the train, the force of the launch, and the wind can stall a train on the top of the tower. When this happens, a mechanic takes the elevator to the top and pushes the train down the hill. This has only happened three times with passengers on board, June 24, 2005, October 25, 2008, and May 25, 2009
When Top Thrill Dragster first debuted, it set four new records:
World’s tallest complete circuit roller coaster
World’s tallest roller coaster
World’s tallest roller coaster drop
World’s fastest roller coaster
It was the fourth roller coaster to break the 100 miles per hour (160 km/h) speed barrier. It was preceded by Tower of Terror II at Dreamworld, Superman: Escape from Krypton at Six Flags Magic Mountain and Dodonpa at Fuji-Q Highland.
The previous record holder for overall height was Superman: Escape from Krypton at Six Flags Magic Mountain, standing at 415 feet (126 m). Its record was broken in 2005 when Kingda Ka opened at Six Flags Great Adventure, standing 456 feet (139 m) tall.
The previous record holder for speed was Dodonpa, at 107 miles per hour (172 km/h). This record was broken by Top Thrill Dragster, which reaches speeds up to 120 miles per hour (190 km/h), which was later broken by Kingda Ka which reached a top speed of 128 miles per hour (206 km/h). In November 2010, Formula Rossa at Ferrari World broke the record for fastest roller coaster, with a top speed of 149.1 miles per hour (240.0 km/h).
