Abstract: A rail splice plate kit comprising first and third rap holes that align with first and third rail holes on a first rail to be spliced, second and fourth rsp holes that align with second and fourth rail holes on a second rail to be spliced, and the first, second, third, and fourth rsp holes are substantially circular. The rail splice plate kit comprises four rail bolts which have a cross section that is within 1/16 of an inch of a diameter of the first, second, third, and fourth rsp holes. The diameter of the first, second, third, and fourth rsp holes may be no more than 3/64 larger than the cross section of the rail bolts. The rail splice plate and the bolts are formed of steel. Adjacent rsp holes are spaced 5 inches from center from one another and a cross section of the rail splice plate is arcuate.

Abstract: A rail fastening device comprises a clip (10) having a base (11) and a nose (12) for engaging a rail flange (F). The base (11) comprises circular aperture (14) in which a circular cam (13) is rotatably mounted, the cam (13) being provided with an eccentric aperture (24) for receiving a ground anchor (25), the cam aperture (24) being radially offset from the rotational centre of the cam (13) to define a cam lobe (15). The cam (13) may comprise a ramped circumferential shoulder (18) to engage a complementary shoulder (21) inside the base aperture (14) such that any rotation of the cam (13) under the applied load of the rail causes the cam (13) to move axially of the base aperture (14) thereby tightening the engagement of the anchor (25) on the cam (13) and preventing movement of the clip (10). The degree of rotation of the cam (13) may be limited so that it can only turn in the tightening direction under load.
