摘要

The method for levelling a railway track comprises reducing the frost protection layer (3) under the concrete track bed (2) so that the track is lowered and any unevenness is removed. The frost protection material may be removed by inserting a pipe (13) and causing it to vibrate while the material is sucked out.
