ABSTRACT:
A railroad crossing structure for providing an improved devil strip. In particular, the invention proposes to bridge the span between adjacent sets of tracks with bridge members of steel or other like material of sufficient strength and rigidity. These bridge members preferably correspond in number to the ties supporting the rails in the area of the crossing, and are secured to them in any suitable fashion. The bridge members may be leveled to provide a flat horizontal surface by notching the ties to receive the ends of the bridge members. The space between the ends of the bridge members and the rails are filled with shims. Thereafter, an elastomeric surface is provided atop the bridge members, using elastomeric pads preferably of the type disclosed in the above-mentioned U.S. Pat. No. 4,093,120. Elastomeric pads of the type disclosed in this patent are preferred since the pads can be easily affixed atop the bridge members because no spikes are required. When the area between the rails is provided with similar elastomeric pads as disclosed in this patent, the resulting railroad crossing structure is entirely covered with an elastomeric surface.
