Abstract

Abstract A track section for model vehicles adapted to be interconnected with like adjacent track sections includes a longitudinally extending body having a top wall, first and second end faces and first and second sides. First and second teeth extend transversely from the body proximate the sides and the end faces in transversely opposite directions away from the centers of the end faces. First and second receiving members are fixed relative to the body proximate the sides and the end faces, each receiving member defining a recess adapted to receive a corresponding tooth of a like adjacent track section. First and second transverse flexion stabilizing members project longitudinally outward relative to the respective first and second receiving members. First and second lugs are mounted to the sides of the body proximate the teeth, each lug defining a cavity adapted to receive a corresponding transverse flexion stabilizing member of a like adjacent track section. Holding elements are mounted to each of the end faces for releaseable inter-engagement with holding elements of a like adjacent track section to resist lateral movement between the track sections upon the track sections being laterally engaged, with a tooth of each track section being received by a recess of a like adjacent track section.
