Abstract (en)
[origin: US4728032A] A railroad track including rails and transversely extending ties. The end portions of the ties are placed on a rigid substructure. For reducing the sound emission, loading members are placed on the ties between the rails. These loading members have an essentially T-shaped cross-section, wherein the horizontally projecting portions are placed on adjacent ties. Sound-insulating elastic inserts may be provided between the ties and the loading members. Consequently, no fittings for fastening the loading members are required. In addition, the space existing between the ties is utilized in an optimum manner by filling it with sound-insulating material.
