A monitoring apparatus for mechanical joints of railway rails is provided. The monitoring apparatus has a tubular shaped body, two terminations disposed at ends of the tubular shaped body, and a strain gauge placed inside the tubular shaped body between the two terminations, stabilized to and integral with an end of a railway rail. The strain gauge is configured to be blocked and tensioned so that a variation of length and mechanical tension of the strain gauge, caused by a relative movement of the two terminations, is matched by a variation of a wavelength of an optical signal passing through the strain gauge. A railway track and a kit for a railway mechanical joint including the monitoring apparatus are also provided.
