It is, for example, on the supply of track construction sites with track construction materials, for example with gravel material, on the one hand, and PSS material (for example in shape a mixture of round grain material and sand), on the other hand.

If you want to achieve an hourly output of 100 meters of track in accordance with an ambitious goal, you will need, for example, 250 m 3 of ballast and 450m 3 PSS material per hour of new substances. With a shift duration of, for example, 12 hours, approximately 8,400 m 3 of new substances are needed, which must be transported via the working track to the track construction site (construction tip), since an existing operating track for rail traffic is still needed.
