ABSTRACT:
A railroad track mounting arrangement for mounting a detecting device in proximate relation to a rail head portion of a section of rail includes first and second V-shaped rail clamp member which exhibit inner contours substantially equivalent to the outer contour of the rail base such that a tight fit is achieved therebetween. A side mounting portion extends from the rail clamp members at a point where, upon installation of the rail clamps, the side mounting portions are in close proximity to the rail base. A mounting bracket secures to the side mounting portion and has a base portion for holding in a secure manner the detecting device. A nut and bolt arrangement secures the rail clamps together and, in the event of overtightening, fractures, thereby insuring positive detection of a faulty installation.
