Embodiment Construction
[0054]FIG. 1 is a prospective view of the preferred embodiment of the improved composite tie 20. The improved composite tie 20 has a top 22, a bottom 24, two opposing ends 26, and two opposing sides 28. The improved composite tie shown in FIG. 1 has three cavities 30 located in the side 28 of the tie 20. The backside 28 (not shown) of the tie 20 also has three cavities 30 which correspond to those shown in the front side 28 shown in FIG. 1. When the tie 20 is installed, the rail is attached to the tie 20 generally in the area indicated 32. The rails are attached to the tie 20 using railroad spikes, screws, brackets and / or other fasteners typically well known in the industry.
[0055] When the tie 20 is in use, the weight and force from the train is transferred through the rails generally into the area indicated as 32, the majority of these forces are in compression. As such, the railroad tie 20 does not need to be a solid rectangular block in order to handle these loads. Therefore, th...
