A track section contains guide grooves for guiding model vehicles and electrical contacts for supplying power to the vehicle. The track section includes provision for rapid and positive mechanical and electrical interconnection with like adjacent track sections by registration of mating parts and simple lateral movement between sections. A single hook and a single corresponding opening on each end of the track section engage with mating elements on like adjacent track sections to permit connection therebetween. Enlarged guide areas appear at the ends of the guide grooves proximate the ends of the track section. The guide areas are in at least partial alignment with like guide areas of like adjacent track sections thereby permitting relatively smooth guidance of model vehicles from one of said track sections to another of said like adjacent track sections despite misalignment between the guide grooves of said track sections.
