Time Machine, Steel roller coaster in Hạ Long, Vietnam

Dragon's Run is a steel roller coaster built by Bolliger & Mabillard, now at Dragon Park Ha Long in Vietnam. Its 1,139-metre track climbs a 47-metre lift hill and reaches 105 km/h through six inversions, including two vertical loops, a cobra roll, a zero-g roll and a corkscrew. Trains seat 32 riders in eight rows of four.

Built by Bolliger & Mabillard, the coaster opened on April 15, 2008 as Led Zeppelin – The Ride, a flagship of Hard Rock Park in Myrtle Beach. After the park's bankruptcy, new owner FPI MB Entertainment renamed it The Time Machine for Freestyle Music Park's May 23, 2009 reopening. That park closed in September 2009, and the dismantled ride reopened on January 25, 2017 as Dragon's Run at Dragon Park Ha Long, Vietnam.

The coaster's soundtrack changed with its name: as Led Zeppelin – The Ride it played the band's "Whole Lotta Love" through onboard speakers, and as The Time Machine it carried a selection of songs from the 1960s to the 2000s. Trains have eight single-row cars seating four across, 32 riders in all.

The ride stands at Dragon Park Ha Long in Quảng Ninh province, Vietnam, where it reopened on 25 January 2017. Riders are seated four across in eight single-row cars, 32 per train, and must clear the 155-foot (47 m) lift hill and 150-foot (46 m) first drop. The circuit runs 3,738 feet (1,139 m) through six inversions at up to 65 mph (105 km/h).

The trains have eight single-row cars seating four riders across, for 32 seats per train. When the coaster ran as Time Machine, passengers could choose from five different soundtracks played through speakers built into the trains, a change from the single Led Zeppelin song used at Hard Rock Park.
