Patent ID: 8870129

Claim:
A full flange bearing rail crossing frog and rail arrangement comprising: a. a first frog casting comprising: i. a main line body portion having a main line top surface and a main line flange way, the main line flange way comprising: 1. a main line flange way floor and 2. a main line internal lateral wall portion; and 3. a main line open external lateral side; and ii. a crossing line body portion having a crossing line top surface and a crossing line flange way, the crossing line flange way comprising: 1. a crossing line flange way floor and 2. a crossing line internal lateral wall portion; and 3. a crossing line open external lateral side; the main line flange way floor and the crossing line flange way floor forming an intersection at an intersection level; and b. a first crossing rail having a crossing rail tread bearing surface, the crossing rail disposed along the open crossing line external lateral side, and adjacent the crossing line body portion top surface, such that the crossing rail tread bearing surface is vertically aligned with the crossing line body portion top surface; and c. a first main rail having a main rail tread bearing surface, the main rail disposed along the open main line external lateral side, and adjacent the main line body portion top surface, such that the main rail tread bearing surface is vertically aligned with the main line body portion top surface; d. a second frog casting comprising: i. a main line body portion having a main line top surface and a main line flange way, the main line flange way comprising: 1. a main line flange way floor and 2. a main line internal lateral wall portion; and 3. a main line open external lateral side; and ii. a crossing line body portion having a crossing line top surface and a crossing line flange way, the crossing line flange way comprising: 1. a crossing line flange way floor and 2. a crossing line internal lateral wall portion; and 3. a crossing line open external lateral side; the main line flange way floor and the crossing line flange way floor forming an intersection at an intersection level; and e. a second crossing rail having a crossing rail tread bearing surface, the crossing rail disposed along the open crossing line external lateral side, and adjacent the crossing line body portion top surface, such that the crossing rail tread bearing surface is vertically aligned with the crossing line body portion top surface; and f. a second main rail having a main rail tread bearing surface, the main rail disposed along the open main line external lateral side, and adjacent the main line body portion top surface, such that the main rail tread bearing surface is vertically aligned with the main line body portion top surface, the first frog casting and the second frog casting arranged so as to form a continuous main line flange way floor and continuous crossing line flange way floor.
