  • Track replacement apparatus of this general type has been described, for instance, in our US. Pat. No. 3,330,219, dated July ll, 1967, and US. Pat. No. 3,521,565, dated July 21, 1970.
  • Such apparatus includes a first train section of cars moving on the old track rails and a second train section of cars moving on the new track rails.
  • various means are arranged for movement in the trackless intermediate section of the right of way independently of the movement of the train sections, which sections also move independently of the each other.
  • the independently movable means include implements for receiving and/or laying track parts, and for working on the ballast.
  • the accuracy and quality of the track replacement also suffer because of varying distance between the point where the old track parts are received and the point where the new track parts are laid correspondingly varies the conditions for the guidance and fixing of the rails.
  • the rails are subjected to flexing as they are lowered from the transport cars to the intermediate section where they are laid or where they are lifted to enable work to be done on the ballast, the flexing load depending on the curvature of flexing which is a function of the distance between the transport cars and the point where the rails are laid.
  • an intermediate train section bridges the trackless intermediate section of the right of way.
  • the intermediate train section is respectively linked, for instance by pivotal couplings, to the first and second train sections to interconnect the same for common movement, and means is provided for maintaining the respective linking means at a predetermined, preferably adjustable, distance in the direction of the right of way.
  • the desired operation of these implements is further facilitated and simplified by selectively operable vehicles arranged to move on the track and to move on the trackless intermediate section of the right of way, preferably including full-track vehicles capable of moving on the ballast in the intermediate section.
  • This feature enables the intermediate train section to start or stop its track renewal work without any change in the structure, and thus to change from a forward movement during renewal to a forward movement from one renewal site to the next.

  • An intermediate train section is shown to comprise a frame 16 which is a connecting part between the first and second train sections, and whose respective ends carry full-track vehicles 17, 17 which are selectively operable for moving on the ballast in the intermediate section of the right of way, an end bracket of the support extending over and being supported on the frame 16.

  • the machine is operated from stand 28.
  • Ballast cleaning machines of this and similar types are known and may include ballast storage containers to supply controlled quantities of ballast to selected portions of the ballast bed.
  • the chute 25 is mounted on a first car 26 of the rear train section.
  • car 26 carries a trolley 4 for transporting the new ties 27 from the cars 2 and to place them in position for laying as the trolleys run forwardly over the flat platforms of these cars.
  • All the cars of the second train sections have running gears 8 moving on the new track rails 10.
  • the pivotal connection of the second train section to the intermediate train section is a mirror image of the above-described connection thereof to the first train section, thus including the support 14 with the vertically adjustable vehicle 15 and a support arm 11.

  • a second conveyor 22 moves the waste ballast laterally away from the ballast bed.
  • a third conveyor 30 moves cleaned ballast towards the input side of the bucket conveyor 19.
  • the distance between the last car 3 of the first train section and the first car 26 of the second train section may be adjustable. This distance is selected in dependence on the working conditions and, more particularly, the flexing load to which the new rails to be laid and the old rails to be taken up is subjected, these loads varying with changing levels of the rails. Excessive loads must be avoided to prevent stresses in the rails which lead to permanent deformations thereof. In this respect, it is also important to note that the rails must be guided and spread without undue friction.
  • the train assembly of the present invention need not include a ballast cleaning machine in the intermediate trackless section of the right of way but have other devices for working on or treating the ballast in this trackless section, as will become evident from the following description of other embodiments of the intermediate train section holding the first and second train sections at a predetermined, preferably adjustable distance.
  • the intermediate train section may consist merely of a spacing rod 16' whose ends are linked respectively to the last car 3 of the first train section and the first car 26 of the second train section.
  • the spacing rod is a telescoped structure enabling the length of the rod, and thus the distance between the first and second train sections, to be adjusted to a selected length.
  • rods may be detachably connected and selectively exchanged.
  • a frame such as 16

  • the ties are securely fixed in position.
  • the laterally extending mounds of ballast seen in FIG. 7 are produced by the ballast moved to the sides of the track by conveyor 24, and this excess ballast may be used to fill the cribs.
