Abstract
A toy vehicle trackset includes a base supporting a vertically extending tower. A toy vehicle trackway includes a vertically rising portion supported by the tower which transitions to a vertical loop and a plurality of helically arranged downwardly spiraling track loop portions. The track loop portion form intersections with the vertically rising portion of the track. Each intersection is covered by a shroud to prevent injury to a child user in the event of collisions within a given intersection. The trackway includes a return which is coupled to a toy vehicle accelerator whereby toy vehicles repeatedly cycle through the trackway set.
