ABSTRACT:
A fabric insertion system for placing fabric in the rock ballast roadbed of an existing railroad track at a predetermined depth beneath the ties of the track includes a car for supporting a roll of fabric which is to be inserted into the ballast. A fabric insertion sled is secured to the car in position beneath the car in the ballast at a predetermined depth beneath the ties. The sled receives fabric from the car and the fabric is diverted within the sled such that it emerges therefrom at the depth of the sled. Fabric is continuously inserted into the ballast as the car and sled are moved along the track.
