A track structure for a toy construction set. A box-like structure is formed by a plurality of closely spaced, generally X-shaped track braces, which support elongated tubular flexible track. elements by track supports at the upper extremities of the "X". The track elements have longitudinally extending slots therein to tightly receive the track supports. The track braces are supported and positioned by means of longitudinally extending rods, arranged in parallel relation to the track elements and secured to the track braces by a snap-in engagement of the rods with open-ended gripping sockets formed by the lower extremities of the X-shaped track braces. A plurality of track braces may be mounted on a single pair of rods, and rods may be connected together end to end to make a track assembly of any length. The flexible track elements may be of more or less continuous length. A rugged track structure is formed, which may be shaped in a variety of vertically and/or laterally varying contours by adjustment of the track braces with respect to the rods and track elements. The track structure may also be arranged in a twist configuration by rotationally displacing adjacent track braces. The structure is particularly advantageous for constructing a toy roller coaster or ball track, for example.
