Multipurpose Stoneblower

Multipurpose Stoneblower

Harsco Rail’s Multipurpose Stoneblower is a revolutionary machine developed specifically as an alternative to traditional tamping methods for the restoration of track’s vertical and lateral alignment. The result is a smooth track surface which is immediately available for unrestricted line speeds.


  • Pneumatically injects ballast under the tie to achieve track position accuracy of 1.0 mm without disturbing the pre-existing compacted foundation
  • Track remains in position much longer than track maintained by traditional tamping methods
  • Track immediately opened at line speed after stoneblowing
  • Post maintenance record of quality immediately available
  • On-board crane loads machine completely with stone in less than one hour
