Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from provisional U.S. Patent Application Ser. No. 60 / 468,096, which was filed on May 6, 2003.FIELD OF THE INVENTION

[0002] The present invention relates generally to the field of railway tracks, and more specifically to cross-ties that are used with railway tracks. BACKGROUND OF THE INVENTION

[0003] Railway vehicles that use linear induction motors (LIM) as their primary source of propulsion are known in the art. In general, linear induction motors (LIM) used by railway vehicles consist of a primary portion that is supported under the railway vehicle, and a reaction rail that is supported on the railway track. As such, railway tracks built for LIM railway vehicles include a pair of running rails for supporting the wheels of the railway vehicle, and a reaction rail for interfacing with the primary portion of the linear induction motor. In addition, railway tracks for LIM railway vehicles include at least ...
