Abstract (en)
A rail fastening device for flat bottom rails laid on a concrete slab-type track comprises a pair of identical gauge adjustment collars (4, 5) each having an aperture (6) such as to pass over a respective one of a pair of mounting blocks (1, 2) embedded in or secured to the track on either side of a rail (3) the aperture (6) being eccentric to provide at least two walls (e.g. a, d) of different thickness for lateral adjustment of the position of the rail (3) with respect to the mounting blocks (1, 2). A further pair of collars (12, 13) each with a concentric aperture (14) are in one embodiment of the invention located over the respective lateral adjustment collars (4, 5). A securing device (15) such as a spring clip is located between each mounting block (4, 5) and the respective height adjustment collar (12, 13) to exert clamping pressure on the rail.
