KINGS ISLAND, Ohio – A train on the new record-breaking Banshee roller coaster at Kings Island goes through a loop encircling the lift hill during a test run.

The world's longest inverted roller coaster at 4,124 feet will send riders screaming through seven stomach-churning inversions at speeds up to 68 mph.
