1. A joint connector bar for connecting adjoining end portions of rails of different height in a track structure, the adjoining end portions of the rails each having oblique surfaces, the oblique surfaces of the adjoining end portions of the rails including: an upper arcuate oblique surface formed below a head portion of the rails extending arcuately inwardly towards a web portion of the rails, and a lower planar oblique surface formed sloping upwardly on a foot portion and extending inwardly towards the web portion of the rails, the leveling joint connector bar comprising: a joint body member to span the adjoining end portions of the rails to be joined and having a number of connector holes formed therein aligned with connector holes in the web portions of the adjoining end portions of the rails to be joined;the joint body member having an arcuate oblique upper surface formed with and extending along the length of the joint body, the arcuate oblique upper surface of the joint body member being machined to conform to and engage along its extent with the arcuate inwardly extending upper oblique surfaces beginning at a lower end of a side wall below the head portions along their inward extent towards the web portions of the adjoining end portions of the rails to be joined;the joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a first segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a first of the two rails to be joined;the joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a second segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a second of the two rails to be joined;the arcuate oblique upper surface of the joint body member and the upwardly sloping planar oblique lower surface of the first segment of the joint body member being spaced from each other along the first segment of the joint body member a distance corresponding to the height of the web portion of the first of the two rails to be joined; andthe arcuate oblique upper surface of the joint body member and the upwardly sloping planar oblique lower surface of the second segment of the joint body member being spaced from each other along the second segment of the joint body member a distance corresponding to the height of the web portion of the second of the two rails to be joined. 2. The joint connector bar of claim 1, wherein the joint body member has a support segment extending outwardly from the lower end of the side wall surface of the head portions of the adjoining end portions of the rails to be joined to provide additional strength to the assembled joint. 3. A rail track structure formed at adjoining end portions of rails have differing characteristics, comprising: a first track portion and a second track portion, each having a web portion, a base portion and a head portion, the web portions of the first and second track portions having a number of connector holes formed therein for the passage of connectors at their end portions, the first and second track portions being of different height from each other;the first and second track portions each having upper arcuate oblique surfaces formed below the head portions thereof, the upper arcuate oblique surfaces extending inwardly towards the web portions of the track portions;the first and second track portions each further having a lower planar oblique surface formed sloping upwardly on a foot portion and extending inwardly towards the web portion thereof;a joint body member to span the adjoining end portions of the first and second track segments to be joined and having a number of connector holes formed therein aligned with connector holes in web portions of the adjoining end portions of the first and second track segments;the joint body member having an arcuate oblique upper surface formed with and extending along the length of the joint body, the arcuate oblique upper surface of the joint body member being machined to conform to and engage along its extent with the arcuate inwardly extending upper oblique surfaces beginning at a lower end of a side wall below the head portions along their inward extent towards the web portions of the adjoining end portions of the rails;the joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a first segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a first of the two rails;the joint body member further having an upwardly sloping planar oblique lower surface formed with and extending along the length of a second segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a second of the two rails;the arcuate oblique upper surface of the joint body member and the lower planar oblique surface of the first segment of the joint body member being spaced from each a distance corresponding to the height of the web portion of the first of the two rails; andthe arcuate oblique upper surface of the joint body member and the lower planar oblique surface of the second segment of the joint body member being spaced from each a distance corresponding to the height of the web portion of the second of the two rails. 4. The rail track structure of claim 3, wherein the joint body has a support segment extending outwardly from the lower end of the side wall surface of the head portions of the adjoining end portions of the rails to be joined to provide additional strength to the assembled joint. 5. The rail track structure of claim 3, wherein the joint body member is located on a first side of the adjoining end portions of the first and second track segments, and further including: a second joint body member bar mounted on an opposite side of the adjoining end portions of the first and second track portions from the first side to span the adjoining end portions of the first and second track segments to be joined and having a number of connector holes formed therein aligned with connector holes in the web portions of the adjoining end portions of the first and second track segments to be joined;the second joint body member bar having an arcuate oblique upper surface formed with and extending along the length of the joint body, the arcuate oblique upper surface of the second joint body member being machined to conform to and engage along its extent with the arcuate inwardly extending upper oblique surfaces beginning at a lower end of a side wall below the head portions along their inward extent towards the web portions of the adjoining end portions of the rails;the second joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a first segment of the second joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface on the base portion of the first of the two rails;the second joint body member further having an upwardly sloping planar oblique lower surface formed with and extending along the length of a second segment of the second joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of the second of the two rails;the arcuate oblique upper surface of the second joint body member and the lower planar oblique surface of the first segment of the joint body member being spaced from each a distance corresponding to the height of the web portion of the first of the two rails; andthe arcuate oblique upper surface of the second joint body member and the lower planar oblique surface of the second segment of the joint body member being spaced from each a distance corresponding to the height of the web portion of the second of the two rails.
