Abstract:
1. A method of making a special track assembly for supporting a train, the special track assembly being at least partially supportable by supporting material, the method comprising: (a) providing a special track segment comprising: the special track segment being at least partially defined by a plurality of exterior surfaces and the top surfaces thereof; (b) attaching a plurality of ribs comprising a resilient material to the exterior surfaces, adjacent ones of the ribs being spaced apart from each other by predetermined distances to define gaps therebetween respectively; (c) attaching at least one wall portion of the resilient material to the ribs, for bridging each said gap to at least partially define a plurality of cavities between said adjacent ribs respectively, said at least one wall portion being deflectable for dissipating energy transmitted by movement of the special track segment relative to the supporting material; and (d) curing the ribs and said at least one wall portion, to form the ribs and said at least one wall portion into a unitary covering, including curing the unitary covering to adhere to the exterior surfaces for engagement with the supporting material.
