  • the method for rehabilitating a track 20 in at least two construction phases I, II using at least one work car 1 is described in Fig. 28 outlined and includes, in the first construction phase I, the removal of excavated material 25 that accrues at a rehabilitation site of the track 20 to be renovated.
  • the work car 1 (the work cars 1) are provided at the rehabilitation site on a second track 20 adjacent to the track 20 to be renovated and the trough(s) 4 are loaded with the excavated material 25.
  • step b) the work car 1 (the work cars 1) are moved with the excavated material 25 from the rehabilitation site to an interim or final storage facility, where in step c) the trough(s) 4 are unloaded next to the track 20 by tipping the trough 4 over the first or second tipping axis K1, K2, as in Fig. 5, 6 and also in Figs. 18, 20 can be seen.
  • Step d) refers to the optional repetition of steps a) to c) and comprises the movement of the work car 1 (the work car 1) unloaded at the interim storage facility onto the second track 20 at the rehabilitation site until the excavation work at the rehabilitation site is completed.
  • the work car(s) 1 will be deployed at the rehabilitation site to fill the rehabilitated track 20 with backfill ballast 25.
  • the work car(s) 1 will be provided at a new material storage facility, and the trough(s) 4 will be loaded with backfill ballast 25. Loading equipment such as excavators or wheel loaders will be used for this purpose.
  • the new material storage facility can be located at the same or a different location as the interim storage facility in construction phase I.
  • step B the work car(s) 1 with the backfill ballast 25 will be moved from the new material storage facility to the rehabilitation site, now on the already rehabilitated track 20.
  • step C the trough(s) 4 will be tipped over the third tipping axle K3, and the backfill ballast 25 will be installed into track 20. as in the Fig. 7 to 10 , and using filling devices 10 in Fig. 11 to 16 is shown.
  • the backfill ballast 25 is installed in layers between the sleepers 24, centrally and laterally, up to the standard bedding profile.
  • the backfill ballast 25 falls from above into the so-called track grid and is preferably filled/introduced into both the track side areas 21 and the track center area 22 during forward movement across the track.
  • work car 1 can also be used to transport other new materials such as gravel/roadside material/ballast during track rehabilitation.
  • work car 1 is also loaded with the new material at an intermediate or new material storage facility, but the transport to the rehabilitation site takes place on the adjacent track 20, and unloading is performed by tipping over the first or second tipping axle K1, K2 next to track 20.
  • the Work Car 1 can thus be used for different work steps in various construction projects during different construction phases. This reduces the investment and maintenance costs for a car operator, as well as the direct installation costs on the construction site. Furthermore, the logistical handling of a single car type is easier than when using multiple car types.
