ABSTRACT:
A continuously advancing dynamic track stabilization machine comprises a first cross level measuring element arranged at the machine frame front end and generating reference signals corresponding to the measured cross level at successive points as the machine continuously advances, a second cross level measuring element arranged adjacent a track stabilization assembly spaced from the front end and generating a signal corresponding to the measured cross level, and a control for actuating the drives for applying a vertical load to the track rails and for vibrating the track in a horizontal, transverse direction. The control is arranged to receive the reference signals from the first cross level element, to store the received reference signals until the second cross level element has reached the successive points, to compare the stored reference signals with the signals generated by the second cross level element to obtain a control signal, and to transmit the control signal for actuating the drives.
