ABSTRACT:
A light rail and wheel carriage system (11) includes first and second rail assemblies (10, 12) held in spaced parallel disposition by a plurality of support members (14), and cooperating wheel carriage assemblies (42) that mount rail cars onto the rail assemblies. Each rail assembly includes upper and lower elongate tubular rail members (16, 18), vertically spaced by a vertical flange (20). In a preferred embodiment, each rail member has a circular configuration and is bifurcated internally by a received longitudinal edge of the vertical flange. Each wheel carriage assembly includes a carriage frame (48), first and second elongate pivot shafts (52, 54), a set of upper and lower rollers (66, 68, 74, 76), and a compressible strut (82). In a preferred embodiment, a set of upper and lower rollers is pivotally secured to opposite ends of the first pivot shaft. A second set of upper and lower rollers is also pivotally secured to opposite ends of the second pivot shaft. The compressible strut interconnects the upper roller of the first pivot shaft to the lower roller of the second pivot shaft.
