Abstract
A railroad crossing signal foundation 10 comprises a base 11 having a lower concrete slab 15' to which a set of upright guide rods 18 is mounted and upper concrete slabs 15 supported upon the lower slab through which the guide rods extend. A pillar 12 is mounted upon the base that has concrete blocks 16 through which the guide rods extend. The pillar blocks have a support area size substantially less than the support area size of the base slabs such that the pillar may be erected with workers standing upon the base. A concrete crown 13 is mounted upon the pillar through which the guide rods extend. The weight of the foundation components is such that the center of gravity of the foundation is located in the base.
