Abstract: A rail fastening device (100) comprises a lower plate (11) and an upper plate (12) provided with a pair of clips (13) for engaging the rail 16, the upper plate (12) being fastened to the lower plate (11) by a pair of fastening bolts (19) which extend through respective apertures (20) in the upper plate (12), the fastening bolts (19) being slidably mounted to the lower plate (11) for movement in a direction which, in use, extends transverse the rail (16). A jacking bolt (31) is arranged to lift the upper plate away from the lower plate as the bolt (31) is tightened and vice-versa. An alignment bolt extends 33 laterally between the upper and lower plates (11), (12) and is rotatable to displace the upper plate (12) laterally relative to the lower plate (11). A levelling bolt (102) threadably engaged with the lower plate is arranged to lift the lower plate (11) away from the surface on which the device (100) is seated as the bolt (102) is tightened and vice-versa.
