Abstract
A mobile track tamper comprises vibratory tamping tools for tamping ballast under the track ties and ballast removing tools associated with the tamping tools for removing at least a portion of the ballast from a region below the ties intermediate the track rails. The track is surfaced by tamping ballast at the points of intersection between the ties and rails and removing the ballast from between the points of intersection.
Claims21
A mobile machine for tamping ballast under ties supporting rails of a track, adjacent ones of the ties defining cribs therebetween and the rails intersecting the ties at respective points of intersection, which comprises the combination of
- 1. vibratory ballast tamping tools arranged to tamp ballast under the ties at the points of intersection and
- 2. means for removing at least a portion of the ballast from a region below the ties intermediate the track rails, the ballast removing means including
- a. ballast removing tools associated with the tamping tools,
A method of surfacing a track comprising two rails fastened to ties resting on ballast, each tie intersecting the rails at two points spaced transversely of the track and adjacent ones of the ties defining cribs therebetween, which method comprises the steps of
- 1. tamping ballast under the ties at the points of intersection between the ties and rails, and
- 2. removing ballast from underneath the ties between the points of intersection no later than the tamping of the ballast.
