Abstract
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.
