From 1946 until 1970 this coaster operated at Beverly Park in Los Angeles, California, USA.
It was sold to Six Flags Magic Mountain and opened at the beginning of the park's inaugural season in May 1971, where it was known as Clown Coaster. In 1985, the ride was given the name Wile E. Coyote Coaster which lasted until 1998. Next, it was renamed "Goliath Jr." after the park's new hyper coaster in 2001. In 2008, it was again renamed to Percy's Railway with Percy as the front car & his Troublesome Trucks as bonus cars. When the park re-themed that section of the park in 2011 as Whistlestop Park due to Six Flags filing for bankruptcy, it was again renamed Magic Flyer.
