The Tower of Terror II is a steel shuttle roller coaster located at the Dreamworld amusement park on the Gold Coast, Queensland, Australia. When the Tower of Terror opened on 23 January 1997, it was the first roller coaster in the world to reach 160.9 kilometres per hour (100.0 mph) speeds making it the tallest and fastest roller coaster in the world of its time. The ride is situated on the Dreamworld Tower which also houses the Giant Drop free fall ride. The ride was originally known as the Tower of Terror until it was modified and relaunched in September 2010.
The steel and concrete structure cost A$16 million to construct. The original ride featured a shorter, 80-metre (260 ft) tunnel, a rigid lap bar using a hydraulic locking system and would carry 15 passengers at a time.
The relaunched ride takes 14 passengers. It propels passengers to just under 161 kilometres per hour (100 mph) with a maximum of 4.5Gs and 6.5 seconds of weightlessness. As of 2010, the ride is 4th in the tallest roller coaster rankings, 3rd in the tallest roller coaster drop rankings and 4th in the fastest roller coaster rankings.
