Abstract
The compression of ballast for a rail track takes place after two-stage cleaning by a cleaning machine. For this purpose, cleaned ballast is dispensed and a first ballast layer is thereby formed. The rail track which is laid on the first ballast layer has lateral oscillations imparted to it by a front stabilization unit, and the first ballast layer is thereby compressed. The formation of a second ballast layer takes place by a second chute, which second ballast layer is subsequently compressed by a rear stabilization unit.
