1. A movable rail bridge joint arrangement comprising: a. a stationary portion having: a) a first gage side guard plate having a first gage side guard plate interior surface,b) a first field side guard plate having a first field side guard plate interior surface, said first gage side guard plate and first field side guard plate defining a rail channel; andc) a first rail portion disposed in said rail channel and comprising a single machined billet having a gage side and a field side, a lead end, a terminal end, a tread-bearing surface and a lower portion, said lower portion extending substantially the entire distance between said gage side guard plate interior surface and said field side guard plate interior surface, and said first rail portion comprising a flangeway machined alongside said tread-bearing surface;said terminal end of said first rail portion disposed between said first gage side guard plate and said first field side guard plate;b. a movable portion having: a) a second gage side guard plate having a second gage side guard plate interior surface,b) a second field side guard plate having a second field side guard plate interior surface, said second gage side guard plate and second field side guard plate defining a rail channel; andc) a second rail portion disposed in said rail channel and comprising a single machined billet having a gage side and a field side, a lead end, a terminal end, a tread-bearing surface and a lower portion, said lower portion extending substantially the entire distance between said gage side guard plate interior surface and said field side guard plate interior surface, and said second rail portion comprising a flangeway machined alongside said tread-bearing surface;said second guard plate interior surface and said second field plate interior surface defining a space and wherein terminal end of said second rail portion extends outside said space; andwherein said movable portion is adapted to be moved between (1) a raised position and (2) a lowered position adjacent said stationary rail portion, such that said respective tread-bearing surfaces of said first and second portions are in substantial alignment. 2. A movable rail bridge joint arrangement according to claim 1 additionally comprising a base plate supporting said field side guard plate, gage side guard plate, and said rail portion. 3. A movable rail bridge joint arrangement according to claim 1 wherein said flangeway comprises a flangeway floor and wherein said gage side guard plate extends alongside said flangeway floor. 4. A movable rail bridge joint arrangement according to claim 1 wherein said terminal end of said rail portion has a tapered miter joint cut. 5. A movable rail bridge joint arrangement according to claim 4 wherein said terminal end of said rail portion resides between said guard plate interior surface and said field plate interior surface. 6. A movable rail bridge joint arrangement according to claim 4, said guard plate interior surface and said field plate interior surface defining a space and wherein terminal end of said rail portion extends outside said space. 7. A movable rail bridge joint arrangement according to claim 1 wherein said flangeway comprises a flangeway floor, said gage side guard plate has a gage side guard plate top surface, said field side guard plate has a field side guard plate top surface, and wherein said gage side guard plate top surface and said field side guard plate top surface extends above said flangeway floor. 8. A movable rail bridge joint arrangement according to claim 1 wherein said gage side guard plate interior surface defines an insert channel along its top portion, and additionally comprising a top portion insert removably attached into said insert channel. 9. A movable rail bridge joint arrangement according to claim 8 wherein said top portion insert comprises a top portion interior surface, and wherein said top portion interior surface is substantially co-extensive with said gage side guard plate interior surface. 10. A movable rail bridge joint arrangement according to claim 1 wherein said second gage side guard plate interior surface comprises a chamfer cut portion. 11. A movable rail bridge joint arrangement according to claim 1, additionally comprising a stock rail aligned with and attached to each respective said lead ends of said first and second rail portions. 12. A movable rail bridge joint arrangement according to claim 1, wherein said lead ends each have a cross-sectional profile matching that of a stock rail, and additionally comprising a stock rail welded onto each respective said lead ends of said first and second rail portions. 13. A rail bridge comprising a movable rail bridge joint according to claim 1. 14. A movable rail bridge joint arrangement comprising: a) a stationary portion having a first pair of parallel guarded rail sections, each comprising: i. a first gage side guard plate having a first gage side guard plate interior surface,ii. a first field side guard plate having a first field side guard plate interior surface, said first gage side guard plate and first field side guard plate defining a rail channel; andiii. a first rail portion disposed in said rail channel and comprising a single machined billet having a gage side and a field side, a lead end, a terminal end, a tread-bearing surface and a lower portion, said lower portion having flat lateral sides and extending substantially the entire distance between said gage side guard plate interior surface and said field side guard plate interior surface, and said first rail portion comprising a flangeway machined alongside said tread-bearing surface;said terminal end of said first rail portion disposed between said first gage side guard plate and said first field side guard plate;b) a movable portion having a second pair of parallel guarded rail sections, each comprising: i. a second gage side guard plate having a second gage side guard plate interior surface,ii. a second field side guard plate having a second field side guard plate interior surface, said second gage side guard plate and second field side guard plate defining a rail channel; andiii. a second rail portion disposed in said rail channel and comprising a single machined billet having a gage side and a field side, a lead end, a terminal end, a tread-bearing surface and a lower portion, said lower portion extending substantially the entire distance between said gage side guard plate interior surface and said field side guard plate interior surface, and said second rail portion comprising a flangeway machined alongside said tread-bearing surface;said second guard plate interior surface and said second field plate interior surface defining a space and wherein terminal end of said second rail portion extends outside said space; andc) a stock rail aligned with and attached to each respective said lead ends of said first and second rail portions; wherein said movable portion is adapted to be moved between (1) a raised position and (2) a lowered position adjacent said stationary rail portion, such that said respective tread-bearing surfaces of said first rail portions are in substantial alignment with respective tread-bearing surfaces of said second rail portions. 15. A rail bridge comprising a movable rail bridge joint according to claim 14.
