초록

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 utiliz...
