Abstract:
1. A crossing panel for accommodating rolling of wheels of a railcar wheel set of a train, each wheel having a flange and a tread surface, across a crossing point of crossing line rails over an intersecting pair of rails, where the crossing line is at a base elevation, said crossing panel comprising: a. a pair of crossing line rails, each said crossing line rail having a crossing rail tread bearing surface and a terminal end; b. a pair of main line rails intersecting said crossing line rails and comprising a first main line rail and a second main line rail, each having a crown, and defining a transition zone thereabove; c. a plurality of railroad ties adapted to support said crossing line rails; said crossing line rails supported by said ties and angled upwardly from the base elevation toward said first main line rail and terminating such that their tread bearing surfaces at their respective terminal ends are at a height above said crown of said first main line rail; and d. an external frog, being aligned with and secured to each said respective terminal end of said crossing line rails, each said external frog having an external frog tread bearing surface at substantially above said first main line rail crown, each said external frog having a flange pathway having a transitional flangeway adapted to engage the flange of a railcar wheel of a train wheel set passing therethrough, such that the tread of said wheel is substantially above the level of said first main line rail crown and contacts said external frog tread bearing surface; and e. an internal casting disposed between said pair of main line rails and respectively aligned with each of said crossing line rails, said internal castings each having a crown maintained at a height sufficient to maintain said railcar wheel of a train wheel set above said main line rails.
