Elevated frog and rail crossing track assembly

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 intersecting rails comprising a first intersecting line rail and a second intersecting line rail, each having a crown, and defining a transition zone above the crown;
• and, on either side of said pair of intersecting rails and approaching respective both said first intersecting line rail and said second intersecting line rail, a crossing line rail set comprising:
• i. a pair of crossing line rails, each said crossing line rail having a crossing rail tread bearing surface and a terminal end;
• ii. a plurality of railroad ties adapted to support said of crossing line rails;
• said crossing line rails supported by said ties and each said crossing line rail angled upwardly from the base elevation toward said respective main line rail and terminating such that its tread bearing surface at its terminal end is at a height above said crown of said respective intersecting line rail;
• and
• iii. external frog castings being aligned with and secured to said respective terminal ends of said crossing line rails, each said external frog casting having an external frog tread bearing surface substantially above the level of said first intersecting line rail crown, each said external frog having a flange pathway to engage the flange of a railcar wheel of a train wheel set passing therethrough, such that the flange of said wheel is above the level of said respective intersecting line rail crown;
• and
• b. transitional guide castings disposed between said pair of intersecting rails and respectively aligned with said crossing line rails, said transitional guide castings being substantially horizontal and each having a crown maintained at a height sufficient to maintain said railcar wheel of a train wheel set above said intersecting line rails.
