Abstract
The present disclosure generally relates to an improved tamping operation where a rail tamping machine advances at different speeds during different stages of tamping and workhead assembly operation. The workhead assembly is also capable of moving longitudinally relative to the rail tamping machine frame when it is detected that the rail tamping machine is at an appropriate distance from a reference point. Related methods of tamping are also described.
