A rail joint arrangement comprises two rails. The rails have adjacent rail ends separated and thereby forming a gap. The rails have a top end containing a rail head and a bottom end. The gap is defined between the top end and the bottom end of the rails, and the width of the gap is non-uniform throughout its entire length. In addition, the rail joint arrangement comprises at least one electric insulator positioned within the gap. The rail joint arrangement is fastened together by a rail joint bar attaching the two rails together.

1. A rail, comprising: a rail body having a first end having a first rail end surface and a second end having a second rail end surface, the rail body having a head portion, a web portion, and a base portion, the first rail end surface having a height and a length, the height of the first rail end s
1. A rail, comprising: a rail body having a first end having a first rail end surface and a second end having a second rail end surface, the rail body having a head portion, a web portion, and a base portion, the first rail end surface having a height and a length, the height of the first rail end surface extending from a top end of the rail body to a bottom end of the rail body, the first rail end surface defined by the head portion, web portion, and base portion is generally Z-shaped having transverse portions extending in a lateral transverse direction relative to a longitudinal axis of the rail body and an angled portion extending between the respective transverse portions, the transverse portions are spaced from each other in the transverse direction and in a direction that extends parallel to the longitudinal axis of the rail body,wherein the first rail end surface at the head portion of the rail body defines a profile that extends the entire length of the first rail end surface and extends from a top surface of the top end of the rail body towards the bottom end of the rail body, the profile being recessed relative to a portion of the first end surface corresponding to the web portion of the rail body. 2. The rail of claim 1, wherein the profile is configured to define a U-shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 3. The rail of claim 1, wherein the profile is configured to define a rectangular shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 4. The rail of claim 1, wherein the first rail end surface at the base portion of the rail body defines a profile configured to define a frusto-triangular shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 5. The rail of claim 1, wherein the profile is configured to define a trapezoidal shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 6. The rail of claim 1, wherein the first rail end surface at the base portion of the rail body defines a profile configured to define a keystone shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 7. A rail, comprising: a rail body having a first end having a first rail end surface and a second end having a second rail end surface, the rail body having a head portion, a web portion, and a base portion, the first rail end surface having a height and a length, the height of the first rail end surface extending from a top end of the rail body to a bottom end of the rail body,wherein the first rail end surface at the head portion of the rail body defines a profile that extends the entire length of the first rail end surface and extends from a top surface of the top end of the rail body towards the bottom end of the rail body, the profile being recessed relative to a portion of the first end surface corresponding to the web portion of the rail body, a dimension of said profile measured in a lateral transverse direction of the rail and the height, is less than a corresponding dimension of said rail head portion measured in a transverse direction of the rail, andwherein the profile is configured to define a U-shaped cross-sectional profile along the entire length of the first end surface when the first rail end surface is positioned adjacent to a corresponding end surface of a second rail. 8. The rail of claim 7, wherein the first rail end surface defined by the head portion, web portion, and base portion is generally Z-shaped having transverse portions extending in a lateral transverse direction relative to a longitudinal axis of the rail body and an angled portion extending between the respective transverse portions, the transverse portions are spaced from each other in the transverse direction and in a direction that extends parallel to the longitudinal axis of the rail body. 9. The rail of claim 7, wherein the first rail end surface defined by the head portion, web portion, and base portion is generally S-shaped.
