Abstract
In a method of operating a tamping unit of a track maintenance machine, the track maintenance machine having the tamping unit is first provided on a track bed. The tamping unit is displaced relative to the track bed. A driving force, acting on the tamping unit and required for the displacement, and acceleration acting on the tamping unit are determined. A ballast force acting between the tamping unit and the track bed is determined by way of the driving force and the acceleration, and is evaluated.
