Out and back roller coaster

Out and back refers to the layout of a roller coaster. An out and back coaster is one that climbs a lift hill, races out to the far end of the track, performs a 180 degree turn and then races its way back to the station. This particular design is very popular and is easy to design and construct. With an out and back design the hills on the way "out" usually are quite large and gradually decrease in size. The hills on the way "back" are usually "bunny hops", or small hills created to maximize air-time.

Double out-and-back

A variation on the theme is to have the track travel from point A to point B, then back to A twice. Examples of this type of ride include the venerable Comet, which was moved from Crystal Beach in Ontario to The Great Escape & Splashwater Kingdom at Queensbury, New York, and the Phoenix at Knoebels' Amusement Resort in Elysburg, Pennsylvania.

Triple out-and-back

These coasters travel back and forth between A and B thrice; the resulting appearance is often hard to discern from true twisters, which are usually free-form in design. An example of this type of ride is the Coney Island Cyclone.
