1. A fastening system for track rail comprising:
a molded support block including a lower side having a base face extending to a lower perimetric edge, an upper side having an upper perimetric edge, and a plurality of outer sides each extending between the lower side and the upper side;
at least two of the outer sides each including a respective planar side face extending continuously from the upper perimetric edge to the lower perimetric edge, and being oriented obliquely to the upper side so as to form a taper that opens in a direction of the lower side;
the molded support block further including retention elements positioned within bores opening at the upper side;
a direct fixation fastener positioned upon the upper side and including a metallic frame having an upper rail plate, and a non-metallic overmolded jacket encasing the metallic frame;
a clearance extends in lateral directions from the direct fixation fastener to the upper perimetric edge, such that the direct fixation fastener is positionable at a range of lateral positions upon the upper side of the support block;
a plurality of clamping fasteners structured to engage with the retention elements to clamp the direct fixation fastener to the upper side within the range of lateral positions; and
reinforcements situated entirely within the molded support block such that the plurality of outer sides are entirely unobstructed from the upper perimetric edge to the lower perimetric edge.
