  • Fig. 13a shows a state without track elevation.
  • the Platform 556 is in a horizontal position parallel to one Floor or frame 572 of the wagon.
  • 13b shows a state with Cant.
  • the floor or frame 572 of the wagon is accordingly inclined to a horizontal plane, but not the platform 556, which continues to assume its desired horizontal position.
  • a track treatment machine or a track treatment train to renew the track substructure or / and proposed the bedding of a track.
  • a reprocessing of the removed, preferably strong, is preferred dirty, track ballast of existing track systems provided.
  • the Track treatment machine or the track treatment train is preferred executed in modular design and can advantageously a module "ballast washer” and a module “water treatment plant” or a module Have "gravel washing system with water treatment system”.
  • the Water treatment system enables water to be reused both within the washing cycle and in the area of responsibility the track treatment machine.
  • the track treatment train made up of individual modules is both for Improvement of the substructure as well as for cleaning the track bed in existing ones Track systems can be used.
  • Substructure material and / or track ballast is made the track, preferably under a rolling wheel, with standard if necessary Excavation chains added and on conveyor belts for loading or to the individual reprocessing modules are promoted for reprocessing, preferably in the working direction.
  • the excavation module preferably leaves a separate loading of substructure material and old gravel too. Both fractions can be in suitable funding Silo wagons are loaded and unloaded separately.
  • Another work module consists, for example, of a two-deck screening machine (Finger sieve / mesh sieve) with which the dismantled and used Reuse suitable crushed stone in both the first and in the second stage separated from loose impurities and simultaneously in two Grit is classified.
  • the sieve residues become the overburden fed and loaded.
  • the work module also has a crusher, who has the task of at least a predetermined gravel stones Grain to undergo a regular treatment to produce the required sharp-edged condition (like new ballast).
  • the smaller fraction can preferably by bypassing the fraction again be fed.
  • the resulting crushed stone fraction is over treated another screening plant again, especially in the case of Screening broken or loosened parts and thus the To further improve the quality of the recycled ballast.
  • the screenings can be added to the other residues.
  • the resulting crushed stone is usually another, having a ballast washer Work module fed.
  • the Ballast with less pollution or / and with minor Track systems bypassed the ballast washing system and immediately for reuse of the built-in part of the track treatment machine can be supplied.
  • the ballast washer enables that for the remanufactured Track ballast achieved a very high quality, up to new ballast quality and accordingly the highest technical delivery conditions enough.
  • the ballast washer can be one or more Have washing screens on which the ballast is created using high-pressure nozzles adhering dirt, which cannot be removed by sieving, is removed from it can be.
  • the at least one washing filter can advantageously at least a washing centrifuge upstream. An if necessary is preferred switchable clay toner provided to be strong even by clay to be able to work up dirty gravel.
  • a further work module is preferably provided, which is a reprocessing of water contaminated during the washing process, so that the Reduce fresh water supply.
  • the polluted water will for example in a so-called clarifier with the addition of vog Flocculant cleaned at least to the extent that it is mixed with fresh water can be used in the car wash.
  • the processed Process water can also be used to moisten subgrade sand or used for the dust-free removal of old ballast.
  • the Fresh water consumption can be reduced by this type of water reuse be greatly reduced, for example by 80 to 90%. Since that If water remains in the working cycle, there is no pollution.
  • the discharge (sludge) can be pumped to the rest of the excavation (overburden) and sieve residues for normal removal.
  • the water treatment module can advantageously be equipped with two inclined clarifiers be executed. Compared to only a longer length oblique clarifier it is advantageous to use two shorter inclined clarifiers, as the Length of the inclined clarifier the cleaning effect becomes less. Further The advantage is that in the event of a malfunction one of the clarifiers, for example, if a sludge discharge belt fails, with accordingly lower performance with the other inclined clarifier can.
  • the installation of two shorter clarifiers is also an example a standard rail car is structurally simpler than installing just one longer clarifier.
  • the work modules mentioned above can also be used as road vehicles Modules for recycling demolition materials.
