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.
