Crossing Diamonds

A Solid Manganese-Steel Crossing has a solid manganese-steel frog at each of the four intersections. These solid frogs are cast with some of the necessary running surface. Depending on the AREA design, guard rails and main rails are specially fabricated from standard tee rails. Heat-treated bolts secure these rails to the castings.
