Abstract: Concrete railroad ties are made having steel plates cast directly into the concrete railroad tie so that the top surface of each steel plate is even with the top surface of the concrete railroad tie. Fasteners for the rails can be welded to anywhere within the steel plate. Additionally, each steel plate can be cast into one of two different positions of the concrete railroad tie thus, creating more flexibility as to the positions of the rail fasteners on the railroad tie and reducing the length of the steel plate needed by half to three inches. By utilizing this assembly, the amount of concrete the patterns needed in a turnout is reduced.

Abstract: The Internally Resilient Railroad Tie consists of two independent booted blocks placed in a tie case, one under each rail. An elastomeric bottom pad is placed under each block inside the boot. The stiffness of the elastomeric bottom pad is varied to compensate for the variations of the overall stiffniess of the track that often involves under-lying materials that are difficult to access for modification or replacement. The mass of the block, suspended between the elastomeric bottom pad and the elastomeric rail pad, provides a damper action that along with the enhanced elasticity of the assembly reduces dynamic impact forces and abates vibrations. The damper system reduces the duration and significance of dynamic peak forces and vibrations. However, variations of any or all of the damper system's components can be used to compensate for the variations of the overall dynamic response of the track where needed.
