Live Coverage: “Roaring Dragon” Roller Coaster’s First Manned Test – Reporters Follow and Film the Entire Journey
At 6 a.m., inspectors used flashlights to check the rail welds.
Before dawn, two inspectors had already climbed the 30-meter-high rails. One used a powerful flashlight to inspect the welds inch by inch, while the other took photos with a tablet computer for record-keeping. The rails gleamed coldly in the morning light, and the headlamps on their safety helmets looked like two stars.
- At 9 a.m., a test was conducted on dummies: eight 120-pound sandbags were launched.
The first round of testing used lifelike dummies, with 60-kilogram sandbags strapped to each seat. The moment the start button was pressed, the train surged forward at 22 meters per second, the wind whipping the dummies' hair straight. Staff closely monitored the acceleration curves on the screens; no abnormalities were observed throughout the entire process.
At noon, the first batch of volunteers experienced...
Ten volunteers boarded the train, one of whom, a young woman, gripped the handrail so tightly her knuckles turned white with nervousness. The train was silent as it climbed, but screams erupted as it plunged. Back at the destination, everyone was laughing.
On-site key：
- At the highest point of the track, in the inverted section, tourists will pause headfirst for 3 seconds as the train passes.
- Four sets of electromagnetic reducers are installed in the braking area, and the red indicator lights illuminate sequentially.
- There are high-speed cameras at the finish line, capturing 500 frames per second for analysis.
At 3 PM, engineers adjusted the brakes, conducting 20 repeated tests. The braking system is crucial for safety, and engineers adjusted it 20 times that day. Each time the train entered the braking zone, the four sets of electromagnetic reducers engaged sequentially, emitting a regular "humming" sound. Test data showed that the stopping position error was no more than 5 centimeters each time.
At 6 PM, the tracks under the setting sun became a popular backdrop for tourists to take photos. Although not officially open yet, many tourists were already taking pictures through the fence outside the park. The sunset bathed the steel tracks in gold, and the curves of the tracks formed a beautiful composition against the sky. One photography enthusiast said, "I'll definitely be the first to come and take the night view photos when it opens."
