With a shift duration of, for example, 12 hours, around 8,400 m 3 of new materials are required, which have to be transported over the work track to the track construction site (construction supervisor), since an existing service track is still required for rail traffic.

  • washing water treatment can be avoided or the effort for washing water treatment can at least be kept small if one is used Wash water for moistening the substructure material to be installed or used to moisten the gravel to be excavated or excavated. Fresh water carried in the track treatment train is then primarily for washing the ballast, but not for moistening it of the substructure material or the ballast.
