An improved track assembly for TV, video and motion picture camera dollys. The inventive assembly includes first and second rail sections. The rail sections are connected by first and second spreaders. Each spreader is pivotally connected to the rails at each end of the spreader. The spreaders retain the first and second rails in a parallel offset relation in a first, deployed, position at which the first and second spreaders are disposed at a ninety degree angle relative to the first and second rails. In a particular embodiment, the first spreaders are coupled to one another by a set of fasteners which are connected to one spreader at one end and hooked onto another spreader at the other end. In the illustrative embodiment, the first and second rails include a male connector at a first end and a female connector at a second end, whereby each female connector on each rail is adapted to receive and retain a male connector from an abutting rail. Each of the rails has a uniform circular cross-sectional area. In the preferred embodiment, each rail is constructed of aluminum or other suitable material and is hollow. The assembly collapses to a second, storage and transport, position at which the first and second rails are parallel to each other and the first and second spreaders remain parallel to each other.
