Through two excitation devices, the WD-320 track dynamic stabilizer causes the track skeleton and ballast bed to produce transverse level vibration and transmit the vertical static pressure to the ballast bed. In this way, the ballast flows and re-arranges to fill each other to make the track sink evenly under control and in the vibration state without changing the original geometry and accuracy, so as to increase the horizontal resistance of operating railway and improve the overall stability of ballast bed. The limit speed conditions after the maintenance operation can be effectively loosened.

After being modified, the stabilizer can be used to stabilize turnouts.
