Abstract
A roller-coaster track includes a vertical loop and terminates in two steep rises, with a loading and unloading station disposed along a horizontal stretch of track between the loop and the lower of the two rises. An endless belt underneath that horizontal stretch entrains a carriage which, when moving along an upper run of that belt, accelerates a passenger train at the station from standstill to a velocity sufficient to let that train pass through the loop in one direction, ascend the higher rise, descend that rise and pass once more through the loop in the opposite direction before ascending and descending the lower rise, eventually coming to rest at the station. The accelerating force is derived, at the start of the ride, from stored potential or kinetic energy such as that of a weight dropping inside a guide tube or a flywheel intermittently coupled with the belt.
