Visitors to Universal’s Epic Universe may have noticed something unusual today: a section of the Stardust Racers track visibly swaying. Videos shared online quickly drew attention, prompting both concern and curiosity among theme park fans. But despite the dramatic footage, engineers and experts say the movement is entirely normal—and an essential part of the coaster’s design.
Video Sparks Online Buzz
Wobbly track section

A video posted to Reddit by user u/xfilesvault has been circulating among theme park communities. The clip shows a section of the roller coaster track shifting back and forth after the train passes over the ride’s “golden arch.” In their post titled “wobbly track section,” u/xfilesvault commented:
“This section of [the] track is extremely wobbly. It looks way worse in person. If you’re in the outdoor section of the queue, look back behind you. This golden arch is constantly wobbling. Not just after the ride cart goes by. Constantly. It’s like it matches the resonant frequency of the entire structure.”
The video, while alarming at first glance, illustrates a common engineering principle: tracks flex slightly to absorb the enormous forces created by high-speed coaster cars. Coaster 101 recently published an in-depth explanation titled “Why Roller Coasters Sway,” which breaks down why movement like this is built into every major coaster design.
Reddit Users Weigh In
The post sparked a lively conversation among coaster enthusiasts and theme park fans. One Redditor reassured others:
“If it doesn’t shake, it’s going to break. I saw this on another coaster and learned coaster tracks have to wobble and sway to absorb the force from the ride. If it were completely rigid it would eventually crack. Probably what’s happening here! (Hopefully)”
Other fans questioned the duration of the sway:
“My main question is… how long should it be shaking like this? This section of track will continue to shake like this a full minute after the ride car passes. The rest of the track only flexes a bit as the ride car passes. It’s very unnerving to watch it continue to move so much for so long after the ride car passes. I probably should have posted a video without the ride car passing.”
Engineering-savvy commenters chimed in, pointing out that movement is expected and designed into large structures:
“In a lot of cases, movement like this is actually part of the design of a structure. Skyscrapers often are built to allow a certain amount of ‘sway’ to prevent high winds from causing more serious damage to the structure.”
Others reassured fans that the ride had been inspected recently:
“This ride has recently been examined by several agencies due to the incident. They have all stated it is operating as designed.”
And one fan offered perspective by comparing it to another well-known ride:
“Go watch Test Track at Epcot. This is nothing.”
Background: A Tragic Incident Earlier This Year
The scrutiny comes on the heels of a tragic incident earlier in 2025. On September 17, 32-year-old Kevin Zavala of Kissimmee was found unresponsive after riding Stardust Racers and was later pronounced dead at a nearby hospital. Authorities attributed the cause of death to “multiple blunt impact injuries,” noting Zavala had a pre-existing spinal condition. Family members described him as a roller coaster enthusiast who enjoyed rides independently.
Following the incident, Stardust Racers was closed for two weeks. Universal conducted an internal review, concluding the ride “functioned as intended” and that “equipment was intact” throughout Zavala’s ride. Florida authorities, including the Department of Agriculture and Consumer Services and the Orange County Sheriff’s Office, conducted their own investigations and confirmed Universal’s findings.
Attorney Ben Crump, representing the Zavala family, has called for additional oversight of ride safety, noting multiple prior complaints about Stardust Racers’ restraints. “These firsthand accounts confirm that Kevin’s tragedy was not an isolated incident,” Crump stated.
Universal Confirms Safety and Updates Procedures
Despite the video and the ongoing discussions, Universal officials have reassured guests that Stardust Racers is safe. A letter sent to employees emphasized safety as the park’s top priority and highlighted updates to operational procedures.
“We are updating operational procedures and attraction signage to reinforce existing ride warnings and physical eligibility requirements at Stardust Racers and other rides,” the company stated.
Track sway is a normal part of roller coaster engineering, designed to absorb stress and extend the life of the ride. For thrill-seekers visiting Epic Universe, the message is clear: the coaster is operating safely, and the visible flexing is intentional.
What Guests Should Know
The sight of a moving coaster track may be unsettling for some, but engineers assure guests that Stardust Racers is functioning as intended. Slight track movement is an expected result of the physics of high-speed rides, and it helps protect both riders and the structure itself.
For fans watching online, the combination of video footage, Reddit discussion, and official statements helps demystify what can appear alarming at first glance. Roller coaster design is as much about engineering precision as it is about thrill—every sway, twist, and flex is carefully calculated to ensure both safety and excitement.
