Track rail fastening mechanism and method

A system for coupling a track rail to a substrate comprising:

• a fastening mechanism including a rail plate, a base plate, and an overmolded coating encasing the rail plate and the base plate, each of the rail plate and the base plate being formed of a metallic material and the overmolded coating being formed of a non-metallic material;
• the rail plate including a lower side structured to face a substrate, and an upper side including a rail support surface extending between a front edge and a back edge of the rail plate, and the rail plate further including an outer perimeter and an inner perimeter defining an opening;
• the base plate including a first lateral end and a second lateral end having a first bore and a second bore formed therein, respectively, and each structured to receive an anchor extending into the substrate;
• and
• the base plate being positioned within the opening such that a gap extends peripherally between the rail plate and the base plate, and the overmolded coating at least partially filling the gap.

A method of fastening a track rail to a substrate comprising:

• attaching a base plate formed of a metallic material to a substrate by way of fasteners extending through bores in opposite lateral ends of the base plate;
• positioning a rail plate formed of a metallic material and surrounding the base plate in a service orientation relative to the substrate by way of the attaching of the base plate;
• and
• clamping a track rail against a rail support surface of the rail plate to establish a load transmission path between the track rail and the substrate by way of a resilient non-metallic material in an overmolded coating encasing the base plate and the rail plate.
