Abstract
A method for compacting a ballast bed, on which railroad ties and track rails secured thereto are supported, uses a work assembly which is arranged on a track construction machine that can be moved on the track. During a compaction process, a signal is detected and a characteristic variable is derived therefrom by an analysis device in order to evaluate the quality of the ballast bed. The work assembly contains an electric drive, by which the compaction process is at least partly carried out. At least one operating variable of the electric drive is supplied to the analysis device, and a ballast bed characteristic variable is derived from the operating variable by the analysis device.
