An arrangement for optically capturing a railroad track includes a carrier device, a camera, and two light sources. The arrangement is mountable on a carrier vehicle that is movable on rails. The alignment of the two light sources and thus the central axes of the emitted light radiation or waves enclose an acute angle with a longitudinal axis of the rail. The light sources are coupled with the camera via control signal lines. The triggering or activation of the light sources is effected via the control signal lines by a predefined control signal. This achieves detailed, sharp image contours that allow high-precision image evaluation and object recognition at the highest possible working speed.

A tamping assembly for tamping sleepers of a track has a tamping unit with tamping tools. The tamping tools are located opposite one another, are mounted on a height-adjustable tool support, and, by way of drives, can be caused to vibrate and can be fed relative to each other. Each tamping tool includes a pivot lever, which can be rotated about a feed axis, and an inner and an outer tamping pick retainer. Each tamping pick retainer can be laterally pivoted relative to the pivot lever. The outer tamping pick retainer can be pivoted about a first pivot axis and the inner tamping pick retainer can be pivoted about a second pivot axis. The second pivot axis is arranged at an offset to the first pivot axis. Thus, it is no longer necessary to adjacently arrange elements for pivoting the tamping pick retainers.
