A method for tamping a track and a tamping machine and a machine group for performing the method.

摘要

In a method for tamping a track track irregularities are identified and thus for optimal Gleiseinschotterung calculated correlating amounts of gravel to be supplied anew and stored by the respective track point location-dependent as ballast requirement value. The stored value is retrieved ballast requirement for release of the corresponding amount of new ballast as soon as a - with respect to the working direction of the measuring device (13) following - has reached the point belonging track Einschottervorrichtung (9). The invention further relates to a tamping machine and a machine group for performing the method.
