The theme park industry thrives on superlatives — tallest, fastest, most inversions. But the pursuit of records has sometimes led to coasters that couldn’t deliver on their promises. Here are the cautionary tales.
Top Thrill Dragster / Top Thrill 2 — Cedar Point
The original Top Thrill Dragster (2003) was revolutionary but plagued by mechanical issues throughout its life. Its replacement, Top Thrill 2, launched in 2024 only to close within weeks due to a defective catch car assembly. It took over a year of redesign work before it could reopen. Total downtime across both versions: over 3 years combined.
Kingda Ka — Six Flags Great Adventure
The world’s tallest coaster at 456 feet has an infamously low reliability rate. High winds frequently shut the ride, and the hydraulic launch system requires extensive maintenance. On busy summer days, Kingda Ka is closed more often than it’s open.
Smiler — Alton Towers
Holding the record for most inversions (14) on opening in 2013, Smiler suffered a devastating crash in 2015 when a loaded train collided with an empty test train. The incident resulted in serious injuries and fundamentally changed how British parks approach ride safety.
Verruckt — Schlitterbahn Kansas City
The world’s tallest water slide at 168 feet was a record that should never have been pursued. Engineering shortcuts and inadequate testing led to a fatal accident in 2016. The slide was demolished, the park closed, and criminal charges were filed. It remains the industry’s darkest chapter.
The Lesson
Records are exciting, but they must never come at the expense of safety and reliability. The best coasters in the world — Iron Gwazi, Fury 325, Velocicoaster — prove that you don’t need to be the tallest or fastest to be the best. You just need to be great.
The industry has learned from these mistakes. Modern engineering and safety standards are more rigorous than ever. But the stories serve as important reminders.
