History

Historical Context

Alton Towers opened The Smiler in 2013, a Gerstlauer steel coaster with a world-record 14 inversions. On 2 June 2015 a fully loaded train collided with a stalled test train, injuring five riders and prompting a £5 million HSE fine and a months-long closure. The later 2026 X2 incident at Six Flags Magic Mountain reflects the same heightened safety scrutiny of high-g rides.
