Abstract:
1. A method of manufacturing railroad cross ties, each of the cross ties having a longitudinal length, said method comprising: providing a plurality of longitudinally extending inner cores for manufacturing a corresponding number of cross ties; securing two adjacent inner cores together in an end-to-end configuration by attaching a connecting member to each of the adjacent inner cores and wherein the connecting member is capable of imparting both compressive and tensile longitudinal forces between the two adjacent inner cores when the two adjacent inner cores are secured together by the connecting member; forming an outer casing on the exterior of the adjacent inner cores; separating the adjacent inner cores to form first and second cross ties by separating the connecting member into a first part and a second part wherein the first part of the separated connecting member forms a portion of the first cross tie and the second part of the separated connecting member forms a portion of the second cross tie.
