摘要： A railroad grade crossing is provided with elastomeric decking pads presenting an upper, vehicular crossway substantially coplanar with the tops of the metallic rails, in turn, secured to the spaced cross ties therebeneath which rest on the roadbed of the roadway. Deck-supporting grillage structure, supported by the cross ties includes a series of spaced cross beams of metallic material arranged to preclude the transmission of electrical currents across the rails. The grill is also provided with spaced, non-metallic, longitudinal beams between the I-shaped cross beams and the deck. The longitudinal beams, to which the deck is attached, rest on the cross ties and are tied to the cross beams. Because of the unique suspension principle which the crossing employs, no drilling of holes in the cross ties is required, nor is any type of fastening to the cross ties required.
