Abstract
During the tamping of a switch, a switch section delimited by two adjacent sleepers is photographed in a front machine section for producing a reference photo, and the photo is stored. The stored reference photo is automatically made available on a monitor, positioned in a work cabin, for observation by an operator as soon as the tamping tools are situated above the section of the switch shown by the reference photo.
Claims4
A method of tamping a switch by immersion of tamping tools into ballast of a track, the method comprising:
- in a forward machine section with regard to a working direction, photographing a switch section delimited by two adjacent sleepers for producing a reference photo, and storing the reference photo;
- automatically making available the stored reference photo on a monitor, positioned in a work cabin, for observation by an operator when the tamping tools are situated above the switch section of the switch shown by the reference photo;
- superimposing a known position of the tamping tools relative to the track on the reference photo to thereby enable the operator to recognize a position of the tamping tools relative to the track;
- and
- immersing the tamping tools into the ballast and tamping the ballast in the switch section.
