2. The rail joint assembly of claim 1 , wherein at least the first surface of the body is peened.

3. The rail joint assembly of claim 1 , wherein the peripheral edge of the body defines a substantially rectangular shape.

4. The rail joint assembly of claim 1 , wherein the peripheral edge of the upper end and the peripheral edge of the lower end of the body have a cutout.

5. The rail joint assembly of claim 1 , wherein the electrically-insulating spacer is porous.

6. The rail joint assembly of claim 1 , wherein the electrically-insulating spacer is mesh.

7. The rail joint assembly of claim 1 , wherein the electrically-insulating spacer is a washer.

8. The rail joint assembly of claim 1 , wherein the first epoxy has a higher durometer reading than the second epoxy.

9. The rail joint assembly of claim 1 , wherein the second epoxy is capable of creating a bond of at least 2000 psi tensile strength and at least 0.003 inch per inch elasticity.

10. The rail joint assembly of claim 1 , comprising a plurality of fasteners passing through the holes of the rail joint bar for securing the rail joint bar to the two abutting railroad rails.

11. A rail joint assembly as claimed in claim 1 , wherein the peripheral edge of the rail joint bar has a recessed portion on an intermediate section of one of the upper end and the lower end, wherein a width, as defined between the upper end and the lower end, is less at the portion of the body containing the intermediate section of the one of the upper end and the lower end than the remainder of the body.

12. The rail joint assembly of claim 11 , wherein the central portion of the first surface of each rail joint bar between the lateral portions of the first surface contains the recessed portion, the recessed portion receiving the second epoxy.

13. A rail joint assembly, comprising:

two abutting railroad rails;

a rail joint bar, the rail joint bar including a body having a first surface, a second surface, an upper end, a lower end and a defining peripheral edge; the rail joint bar having a plurality of holes defined on the body, wherein the holes are adapted to receive fasteners for securing a rail joint between two railroad rails; and

an adhesive sandwiched between the body and the two abutting railroad rails securing the rail joint bar to the railroad rails; the adhesive is dispersed across the first surface of the body and includes a first epoxy on lateral portions of the first surface and a second epoxy on a central portion of the first surface between the lateral portions of the first surface, wherein the first epoxy has a different durometer reading than the second epoxy.

14. The rail joint assembly of claim 1 , wherein the first epoxy is capable of creating a bond of at least 3500 psi tensile strength and at least 0.0012 inch per inch elasticity.

15. The rail joint assembly of claim 14 , wherein the second epoxy is capable of creating a bond of at least 2000 psi tensile strength and at least 0.003 inch per inch elasticity.

16. The rail joint assembly of claim 13 , wherein a peripheral edge of the rail joint bar has a recessed portion on at least an upper surface.

17. A rail joint assembly, comprising:

a pair of abutting railroad rails;

a compressible gasket positioned between the pair of abutting railroad rails; and

a first rail joint bar and a second rail joint bar, each including a body, the first rail joint bar and the second rail joint bar are secured to the abutting railroad rails with a plurality of fasteners passing through the plurality of holes, wherein the adhesive is dispersed across the first surface of the body and includes a first epoxy on lateral portions of the first surface and a second epoxy on a central portion of the first surface between the lateral portions of the first surface, and wherein the first epoxy has a different durometer reading than the second epoxy.

18. The rail joint assembly of claim 17 , wherein the gasket is comprised of a compressible, electrically-insulating material, the gasket having a T-shaped design corresponding with the end profile of a railroad rail.

19. A rail joint assembly as claimed in claim 17 , wherein the compressible gasket comprises a spacer and compressible electrically-insulating material attached to the spacer.

20. A rail joint assembly as claimed in claim 19 , wherein the spacer includes a first face and a second face, wherein compressible electrically-insulating material is provided on each face of the spacer, the compressible electrically-insulating material is compressed by the abutting railroad rails.

21. A rail joint assembly as claimed in claim 20 , wherein the spacer defines grooves into which the respective compressible electrically-insulating material is received.

22. A rail joint assembly as claimed in claim 21 , wherein at least a portion of the electrically-insulating material is arcuate shaped.

23. A rail joint assembly as claimed in claim 22 , wherein the spacer defines a web and the electrically-insulating material is positioned above the web.
