A tamping machine is provided with tamping tools for tamping open track and track adjacent switch gear. Each tool is mounted on an oscillating and pivoting lever which is articulated to a frame mounted for vertical movement in a gantry suspended from the chassis of the tamping machine and movable in both transverse and longitudinal directions with respect to the track. Each tool has two picks with blades of unequal length radially separated from each other and rotationally mounted on the lever in a plane transverse to the track. The two picks on each tool are interchangeable and can be locked into working position. |
