ABSTRACT:
A mobile track tamper comprises a tamping tool assembly mounted on a machine frame for vertical movement. Each tamping tool assembly includes two pairs of vibratory tamping tools spaced from each other in the direction of track elongation so that each pair of tools may be immersed in successive cribs and the two units are so spaced that all four pairs are immersible in successive cribs. The tools of each pair are reciprocable in opposite directions towards and away from the elongated edges of adjacent ties wherebetween the cribs are defined. A common drive vertically moves the tamping tools on a carrier.
