Abstract
A method for stabilizing a track having sleepers supported on a track ballast and rails secured to the sleepers, includes using a stabilizing unit which is connected to a machine frame that can be moved on the rails and has a vibration exciter and rollers that can roll on the rails. The vibration exciter generates in particular horizontal vibrations which run transversely to the track longitudinal direction. The course of a force exerted onto the track by the stabilizing unit is recorded over a vibration path during a vibration cycle by sensors. At least one parameter is derived from the course by an evaluation device and is used to evaluate the stabilizing procedure and/or the quality of the track ballast. A device for implementing the method is also provided.
