World’s tallest and fastest rollercoaster

This is the world’s tallest (310 feet) and fastest (92 mph) rollercoaster, and is supported by 226 footers using 9,400 yards of concrete. It took 175 truckloads of steel make up the frame. One train weighs 19 tons.
This coaster is not only a tribute to its engineers for being the world’s largest, but engineers employed a host of new technologies. For example, the elevator cable system--used for first time on a roller coaster--ensures a smooth trip up the hill, and a magnetic braking system replaces the traditional friction approach.
