Tumble Bug

A Tumble Bug is an amusement park ride with a circular track.

The ride has a central axis and a circular track. The track has changes in elevation in it, and the cars, each attached by a rod to a central pivotal attachment point and connected to one another, are propelled around the track via motors between the cars. Power is carried to the motors via slip ring brushes at the center and cables.

Only one full-sized Tumble Bug remains in operation today at Kennywood in West Mifflin, Pennsylvania. There are multiple kiddie versions of the ride still in operation. All full-size instances were made by Traver Engineering, and its successor, R.E.Chambers. The ride also exists in a miniature children's form. A full-sized Tumble Bug is 100 feet in diameter, and operates with five or six cars, while the kiddie version has three or four cars.
