This record-breaking new 2.5 mile roller coaster will go 150 mph

In 2023, Six Flags Qiddiya will open near Riyadh, Saudi Arabia with the centerpiece attraction of Falcon's Flight, a 2.5 mile-long rollercoaster that speeds along at 150+ mph. From CNN:

Riders will experience the thrill of diving over a vertical cliff into a 160-meter-deep valley (525 feet) thanks to the use of magnetic motor acceleration (LSM technology), and "achieve unprecedented speeds of 250-plus km/h" — about 155 miles per hour.
