Six Flags Magic Mountain opened north of Los Angeles in 1971 and spent the next half-century building one of the world’s most famous collections of roller coasters.

That strategy made it the “Thrill Capital of the World.”

Now the assets that made it famous are becoming a very expensive problem.

X2 has been closed for more than a month while Cal/OSHA investigates an incident involving the ride.

Emergency crews were called July 5 after a rider was reportedly found unconscious. The rider’s condition still hasn’t been publicly disclosed.

And this isn’t X2’s first serious incident.

In 2022, 22-year-old Christopher Hawley lost consciousness after riding X2 and died the next day from a catastrophic brain injury. His family alleges the ride caused his death; Six Flags disputes liability. That case is headed toward trial.

But zoom out.

Last year, Six Flags took a $533.7 million impairment against Magic Mountain — the largest individual park-level write-down disclosed in that round of impairments. (Securities and Exchange Commission)

Meanwhile, much of the coaster fleet that built the park’s reputation is now 20, 30, even 50+ years old.

Superman was permanently retired after replacement parts became obsolete and further investment stopped making economic sense.

That’s important because Magic Mountain isn’t a marginal amusement park. It is the largest private employer in the Santa Clarita Valley, with roughly 3,000 workers. (SCVEDC)

And Six Flags isn’t abandoning it. The company is rebuilding parts of the park and trying to extract more revenue from the people who come.

So this isn’t simply a story about an unsafe roller coaster.

It’s an aging-infrastructure and business-model problem:

Magic Mountain spent decades turning increasingly elaborate machines into its competitive advantage.

Now Six Flags has to spend enormous amounts maintaining, rebuilding or replacing those same machines while trying to make the economics of the park work.

The rides that made Magic Mountain valuable are increasingly becoming the capital obligation Six Flags has to solve.

The $534 million write-down may be the clearest indication yet of how expensive preserving the “Thrill Capital of the World” is going to be.
