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.

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 b...
In a railroad track including rails and ties extending transversely of and connected to the rails, the ties having end portions and portions extending between the rails the end portions of the ties placed on a rigid substructure, sound-insulating intermediate layers placed between the ties and the substructure, and solid loading members of concrete placed on the portions of the ties extending between the rails for reducing sound emission, the improvement which comprises that the loading members have an essentially T-shaped cross-section defining outwardl...
