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.

A rail temperature expansion joint and a laying and mounting method thereof relate to the technical field of track transit. The rail temperature expansion joint includes a sleeper, the upper surface of the sleeper is symmetrically mounted with two first rails and two second rails, and the first rail and the second rail on one side are arranged on the same straight line; a gap is arranged between end faces of the first rail and the second rail; the adjacent ends of the first rail and the second rail are fastened and positioned by a group of adjustment components, the adjustment components are fixedly mounted on the embedded part, and the embedded part is located at the outer side of the first rail and the second rail.
