摘要： The invention relates to a measuring arrangement for monitoring a railway track having rails fastened to sleepers, wherein a fibre optic cable is connected to a measuring device in order to detect a strain acting on a rail. In this, the fibre optic cable is clamped in a detachable manner into at least one rail fastening. In this way, a strain transmitted from the rail via the rail fastening to the sleeper acts directly on the fibre optic cable.

摘要： A fastening point for a rail on a foundation including a bedplate arranged on a support surface of the foundation. The bedplate includes a bearing surface formed on its underside associated with the foundation and also a through-opening, a spring element for exerting an elastic holding-down force on a rail foot and a clamping screw, which braces the spring element against the bedplate. The clamping screw is guided with its threaded shaft through the through-opening of the bedplate. The clamping screw acts with its screw head against the spring element and is screwed into a thread provided in a region of the through-opening of the bedplate. A free space is provided in a region underneath the bedplate in the extension of the through-opening of the bedplate, into which the threaded shaft of the clamping screw can be inserted.
