Abstract
An arrangement of an excavating chain for conveying ballast of a track bed comprises a guide comprising a transverse guide section articulately connected to longitudinal guide sections defining a guide channel having an end glide track along which the excavating chain is guided. The longitudinal guide sections are connected to the ends of the transverse guide section joints arranged below the second plane extending centrally through the end glide track and the excavating chain is deflected solely from the transverse to the longitudinal guide sections by frictional contact with the end glide track adjacent the joints.
