The most substantial and recent story matching the headline’s description is the May 16 incident at Six Flags Over Texas. I’ll write the article based on that well-documented event, as it’s the story that matches the “mass evacuations” and “park closure” details referenced in the headline source.
Riders aboard the Titan coaster at Six Flags Over Texas were evacuated safely Saturday after the attraction stopped during a broader technical outage that disrupted operations throughout the amusement park.
The incident unfolded on Saturday, May 16, when a park-wide outage caused attractions across the property to lose power.
Riders were forced to evacuate a 245-foot-tall roller coaster at Six Flags Over Texas in Arlington after a park-wide power outage forced the ride to stop.

In a statement obtained by PEOPLE, a spokesperson for Six Flags explained that an external construction crew accidentally struck an underground power line, causing the outage that temporarily disrupted operations throughout the park.

One of the most visible impacts occurred on Titan, the iconic hypercoaster that has operated at the park since 2001.
The ride reportedly stopped mid-course after the outage hit, leaving guests suspended high above the park before evacuation procedures began.
Guests riding the Titan roller coaster at Six Flags Over Texas were safely evacuated after a power outage stopped the attraction mid-course, prompting riders to descend a steep emergency staircase attached to the towering structure.

Videos quickly spread online showing guests slowly climbing down emergency stairs attached to the massive steel structure of Titan, a towering attraction that rises 245 feet into the sky.
Guests were seen taking the terrifying walk down emergency stairs alongside the coaster as onlookers on the ground looked up in fear.
Bystanders captured the tense scene unfolding above them.
Guests are already reacting to the footage across social media, with many commenting on just how intimidating the evacuation appeared from ground level. Others noted that while roller coaster evacuations are rare, seeing them happen on such a massive attraction instantly creates anxiety for parkgoers.

The scale of the coaster added to the drama.
Titan remains one of the most intense rides at the park, featuring a 245-foot drop alongside powerful G-force-heavy turns and speeds reaching up to 85 mph.
Park leadership worked swiftly to restore power and reopen.
Fortunately, no injuries were reported during the incident, according to WFAA, as cited by PEOPLE. Six Flags also said all guests were safely escorted off rides and attractions after the outage.
In the viral moment that caught widespread attention, the power outage knocked out multiple rides and forced evacuations across the 65-acre Arlington park.
A power outage at Six Flags forced multiple rides to shut down, with riders seen walking down roller coaster tracks during evacuations.
A Six Flags spokesperson said the park experienced an internal technical issue Saturday afternoon, causing an interruption in power. “At this time, the park is closed while Oncor Electric Delivery works to restore power,” the spokesperson said to WFAA.
Oncor confirmed to WFAA that they had workers on site to provide support as Six Flags addresses the issue and determined the outage was caused by an issue with the park’s electrical equipment.
Roller coaster evacuations are rare, but they are part of the safety planning that allows parks to respond when unexpected outages happen.
For riders, the biggest takeaway is also the most important one: the situation looked frightening, but everyone was safely brought down.
The park reopened at 11 a.m. May 17, a spokesperson said.
