Abstract (en)
[origin: US2004045473A1] A tamping tine for tamping ballast underneath a railroad track has a tine shank and a tine pad attached to the shank. For increasing its abrasion resistance, the tine pad is formed with a pad casing of wear-resistant material. The pad casing is formed with an opening and it is filled with core material. The core material is suitable for welding to the tine shank and it is attached thereto by way of a welding seam.
