Abstract
The invention concerns a track maintenance machine for tamping a track having sleepers supported in a ballast bed with rails fitted to the same, with a machine frame that is mobile on on-track undercarriages and with a tamping unit. Wherein a camera for transmitting real-time images to an output means is arranged upstream of the tamping unit in a working direction. A first camera system is arranged upstream of the tamping unit in working direction here for recording a first surface area of the track as a first image section. In addition, a second camera system is arranged downstream of the tamping unit in working direction for recording a second surface area of the track as a second image section, wherein the recorded image sections partly overlap and wherein the output means is equipped for issuing the image sections in a merged image.
