Abstract (en)

[origin: WO2020233934A1] Track-building machine (1) for tamping a ballast bed (8) of a track (5), having a machine frame (3) which can move on rail bogies (2) and having a tamping unit (4) which comprises tamping tools (11) which can be lowered into the ballast bed (8), can be caused to vibrate and can be adjusted relative to one another, wherein a camera (30) for transmitting real-time recordings to an output device (16) is arranged in a working direction (13) upstream of the tamping unit (4). In the working direction (13) upstream of the tamping unit (4) there is arranged a first camera system (14) in order to capture a first surface region (23) of the track (5) as a first image detail (24, 25). In the working direction (13) downstream of the tamping unit (4) there is additionally arranged a second camera system (15) in order to capture a second surface region (26) of the track (5) as a second image detail (27, 28), wherein the captured image details (24, 25, 27, 28) partially overlap and wherein the output device (16) is designed to output the image details (24, 25, 27, 28) in a combined image.
