Abstract:
A method of placing, positioning and fastening railroad sections on a number of mutually adjacent and mutually spaced loose railroad sleepers, the sleepers each resting loosely on a railroad bed, comprising the steps of:carrying a store of railroad sections on a first railroad wagon;moving a pulling vehicle along a railroad bed;pulling railroad sections from the first wagon into abutment with loosely placed sleepers on the railroad bed with the pulling vehicle;moving railroad sections pulled by the pulling vehicle at a distance above the loosely placed sleepers and along a number of railroad section fastener devices supported by the loosely placed sleepers and through a path conforming to an orientation of the railroad section fastener devices, the railroad sections being moved so that a rear end surface of a pulled railroad section is positioned adjacent a front end surface of an earlier pulled railroad section;activating at least one of the railroad section fastener devices when one of the railroad sections is moved so that its rear end surface is positioned adjacent a front end surface of an earlier pulled railroad section so as to lower said railroad section onto said rail-adapted fastener devices; andfollowing the first wagon with a mobile unit along ones of the railroad sections positioned on loosely placed railroad sleepers to fasten the railroad sections permanently to each loosely placed railroad sleeper.
