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.

A method of operating a tamping unit of a track maintenance machine, which comprises the steps of:
- providing on a track bed the track maintenance machine having a tamping unit;
- displacing the tamping unit relative to the track bed;
- determining a driving force acting on the tamping unit and required for a displacement;
- determining an acceleration acting on the tamping unit;
