A track for a toy vehicle and such vehicle are provided. Each track segment has an upper layer and a spaced apart lower layer. A pivot pin is vertically disposed on a forwardly projecting tongue attached to one of the upper and lower layers, and a rearwardly disposed crossbar is adapted to receive the pivot pin of an adjacent segment. By repeating this pivotable angled structure with a number of segments, the curvature of the track can be altered to the taste and specifications of the user. A pair of flanges project from the top side and form a channel. A toy vehicle engageable with the track includes a retaining knob on its base that is forcibly disposable in the channel. When the retaining knob is forcibly disposed in the channel, the vehicle is retained on the track substantially regardless of angle of inclination or curvature of the track.
