Abstract
For the controlled lowering of a track, a longitudinal inclination of the track is determined at a rear tracing point of a measuring system and stored. For a length reaching back at least 10 meters, a current vertical profile is formed, and a rear compensation straight line is calculated which is superimposed upon the vertical profile and renders a target track position. The rear tracing point is guided by calculation along the rear compensation straight line, so that a compensation value for the position of the measuring chord ensues at a middle tracing point positioned between the rear tracing point and a front tracing point.
