    Abstract: A double tongue and groove rail expansion assembly is provided with ancillary equipment to limit dimensional flexing of a railroad track caused by instabilities in the underlying earthen surface, or variable work loads, or temperature changes effecting the longitudinal dimensions of the rails, or any and all combinations of such stresses. The ancillary equipment includes pushover assemblies for control of lateral and vertical forces, tieplate assemblies for control of longitudinal and vertical forces and an electrical bonding system to maintain electrical balance across the area of rail joinment.
