ABSTRACT:
A tamping tine has a flat inclined tine surface that encloses an acute angle with a front surface of a tine plate at the lower end of a shank. The inclined tine surface is delimited, with regard to a longitudinal direction of the tamping tine, by a bottom edge of the tine plate and by a shank section line defined by an intersection of the inclined tine surface with the entire rear portion of the shank. A reference line on the inclined tine surface is distanced farther from an upper end point—positioned at the maximum distance from the bottom edge of the tine plate—of the inclined tine surface than from a shank end line. This ensures an easier penetration by the tamping tine into the ballast and it provides for an improved attachment of hardened metal plates for providing abrasion resistance.
