PURPOSE: To improve the durability by forming a cloth track floor stabilizing bag arranged under a sleeper, in a track floor or on the lower face of the track floor in such a manner that, at least, the inside face of the bag is the pile-formed face of a pile cloth.
CONSTITUTION: A basic cloth 2 is formed of polyester with a density of 250-750g/m2. A pile 3 is formed of polyester filaments with a density of 200-1500g/m2 and a unit length of 2-20mm. The pile 3 is fitted to the basic cloth 2 to form a pile cloth 1. The pile cloth 1 is sewed in such a manner that, at least. the inside face of a bag is the pile-formed face to form a track floor stabilizing bag A. In this way, a track floor which is releaved from friction and impulse due to load variation with the passing of a vehicle and subjected to almost no mechanical damage shows excellent durability and good stabilization, with no breakage for a long time.
