The coaster is located in the Whistlestop Park area of Six Flags Magic Mountain in Valencia, California.

In the 1984-1985 off-season the ride was renamed and rethemed to Wile E. Coyote Coaster to suit the theme of the nearby Bugs Bunny World.

The Thomas Town at Six Flags Magic Mountain has been renamed and rethemed to Whistlestop Park which reopened on March 19, 2011.
