Abrégé

A clamp (10) to secure adjacent rails (50) suitable for carrying a train or the like together is disclosed, the rail being joined by a fish plate (51a, 51b). The clamp comprises a base plate (11) to support either or both rails. The clamp comprises a jaw block (12) which is releasably secured to a first end of the base plate (11), the jaw block having a pressure surface to engage a fish plate. The base plate further includes a locating aperture (17) defined by the base plate to partially house a second jaw block (13), the second jaw block being movable between a first non-engaging position and a second position engaging a fish plate on the opposite side of the rail. Moving means are provided to urge the second jaw block from the non-engaging to the rail-engaging position.

Abrégé

A rail clamp comprising two clamp elements (30a, 30b) securable together in clamping arrangement about a railway rail, wherein at least one of the clamp elements (30a, 30b) can include sensor retaining means to hold a sensor to make measurements relating to the rail. A first of said two clamp elements (30b) has a clamp head to engage a fish plate (14b) or a web-side of a railway rail. A clamp foot (34b) engages the underside of a railway rail foot (13). A second of said two clamp elements (30a) having a clamp head to engage the opposite fish plate or web-side of a railway rail and a clamp foot (34a) to engage the underside of the clamp foot (34b) of the first clamp element (34b). The first and second clamp elements (30a, 30b) are secured together by a connector (35), optionally a bolt, to a railway rail.
