The brush shaft is rotatable by a drive (17) along a axis of rotation (18), and a hollow shaft (19) is rotatably supported on a line extending in the interior of a control shaft (20). The longitudinal axis (21) of the control shaft is parallel to cross-track direction (14) defined by sleepers (3). The rotation axis (25) of the brush shaft is positionable at an angle to the longitudinal axis or to track plane (22). |
